t. JavaScript:The World's Most Misunderstood Programming Language

Douglas Crockfordwww.crockford.com

JavaScript, aka Mocha, aka LiveScript, aka JScript, aka ECMAScript, is one of the world's most popular programming languages.Virtually every personal computer in the world has at least one JavaScript interpreter installed on it and in active use. JavaScript'spopularity is due entirely to its role as the scripting language of the WWW.

Despite its popularity, few know that JavaScript is a very nice dynamic object-oriented general-purpose programming language. Howcan this be a secret? Why is this language so misunderstood?

The NameThe Java- prefix suggests that JavaScript is somehow related to Java, that it is a subset or less capable version of Java. It seems thatthe name was intentionally selected to create confusion, and from confusion comes misunderstanding. JavaScript is not interpretedJava. Java is interpreted Java. JavaScript is a different language.

JavaScript has a syntactic similarity to Java, much as Java has to C. But it is no more a subset of Java than Java is a subset of C. It isbetter than Java in the applications that Java (fka Oak) was originally intended for.

JavaScript was not developed at Sun Microsystems, the home of Java. JavaScript was developed at Netscape. It was originally calledLiveScript, but that name wasn't confusing enough.

The -Script suffix suggests that it is not a real programming language, that a scripting language is less than a programming language.But it is really a matter of specialization. Compared to C, JavaScript trades performance for expressive power and dynamism.

Lisp in C's ClothingJavaScript's C-like syntax, including curly braces and the clunky for statement, makes it appear to be an ordinary procedurallanguage. This is misleading because JavaScript has more in common with functional languages like Lisp or Scheme than with C orJava. It has arrays instead of lists and objects instead of property lists. Functions are first class. It has closures. You get lambdaswithout having to balance all those parens.

„[Microsoft] did not want to deal with Sun about the trademark issue, and so they called their implementation JScript. A lot of people think that JScript and JavaScript are different but similar languages. That's not the case. They are just different names for the same language, and the reason the names are different was to get around trademark issues.“ (Douglas Crockford)

JavaScript > Excerpts >

This excerpt is from JavaScript: The Good Parts . This authoritative book scrapes away these bad features toreveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole-asubset you can use to create truly extensible and efficient code.

Bad Parts: Appendix B - JavaScript: The Good Partsby Douglas Crockford

And, I pray thee now, tell me for which of my bad parts didst thou first fall in love with me?

--William Shakespeare, Much Ado About Nothing

In this appendix, I present some of the problematic features of JavaScript that are easily avoided. By simply avoiding these features,you make JavaScript a better language, and yourself a better programmer.

==JavaScript has two sets of equality operators: === and !==, and their evil twins == and !=. The good ones work the way you wouldexpect. If the two operands are of the same type and have the same value, then === produces true and !== produces false. The eviltwins do the right thing when the operands are of the same type, but if they are of different types, they attempt to coerce the values.The rules by which they do that are complicated and unmemorable. These are some of the interesting cases:

'' == '0' // false0 == '' // true0 == '0' // true

false == 'false' // falsefalse == '0' // true

false == undefined // falsefalse == null // falsenull == undefined // true

' \t\r\n ' == 0 // true

The lack of transitivity is alarming. My advice is to never use the evil twins. Instead, always use === and !==. All of the comparisonsjust shown produce false with the === operator.

with StatementJavaScript has a with statement that was intended to provide a shorthand when accessing the properties of an object. Unfortunately,its results can sometimes be unpredictable, so it should be avoided.

The statement:

with (obj) { a = b;}

does the same thing as:

if (obj.a === undefined) { a = obj.b === undefined ? b : obj.b;} else { obj.a = obj.b === undefined ? b : obj.b;}

So, it is the same as one of these statements:

a = b;a = obj.b;obj.a = b;obj.a = obj.b;

It is not possible to tell from reading the program which of those statements you will get. It can vary from one running of the programto the next. It can even vary while the program is running. If you can't read a program and understand what it is going to do, it isimpossible to have confidence that it will correctly do what you want.

Simply by being in the language, the with statement significantly slows down JavaScript processors because it frustrates the lexicalbinding of variable names. It was well intentioned, but the language would be better if it didn't have it.

evalThe eval function passes a string to the JavaScript compiler and executes the result. It is the single most misused feature ofJavaScript. It is most commonly used by people who have an incomplete understanding of the language. For example, if you knowabout the dot notation, but are ignorant of the subscript notation, you might write:

eval("myValue = myObject." + myKey + ";");

instead of:

myvalue = myObject[myKey];

The eval form is much harder to read. This form will be significantly slower because it needs to run the compiler just to execute atrivial assignment statement. It also frustrates JSLint (see Appendix�C, JSLint), so the tool's ability to detect problems is significantlyreduced.

The eval function also compromises the security of your application because it grants too much authority to the eval'd text. And itcompromises the performance of the language as a whole in the same way that the with statement does.

The Function constructor is another form of eval, and should similarly be avoided.

The browser provides setTimeout and setInterval functions that can take string arguments or function arguments. When givenstring arguments, setTimeout and setInterval act as eval. The string argument form also should be avoided.

continue StatementThe continue statement jumps to the top of the loop. I have never seen a piece of code that was not improved by refactoring it toremove the continue statement.

switch Fall ThroughThe switch statement was modeled after the FORTRAN IV computed go to statement. Each case falls through into the next caseunless you explicitly disrupt the flow.

Someone wrote to me once suggesting that JSLint should give a warning when a case falls through into another case. He pointed outthat this is a very common source of errors, and it is a difficult error to see in the code. I answered that that was all true, but that thebenefit of compactness obtained by falling through more than compensated for the chance of error.

The next day, he reported that there was an error in JSLint. It was misidentifying an error. I investigated, and it turned out that I hada case that was falling through. In that moment, I achieved enlightenment. I no longer use intentional fall throughs. That disciplinemakes it much easier to find the unintentional fall throughs.

The worst features of a language aren't the features that are obviously dangerous or useless. Those are easily avoided. The worstfeatures are the attractive nuisances, the features that are both useful and dangerous.

Block-less StatementsAn if or while or do or for statement can take a block or a single statement. The single statement form is another attractivenuisance. It offers the advantage of saving two characters, a dubious advantage. It obscures the program's structure so thatsubsequent manipulators of the code can easily insert bugs. For example:

if (ok) t = true;

can become:

if (ok) t = true; advance( );

which looks like:

if (ok) { t = true; advance( );}

but which actually means:

if (ok) { t = true;}advance( );

Programs that appear to do one thing but actually do another are much harder to get right. A disciplined and consistent use of blocksmakes it easier to get it right.

++ −−The increment and decrement operators make it possible to write in an extremely terse style. In languages such as C, they made itpossible to write one-liners that could do string copies:

for (p = src, q = dest; !*p; p++, q++) *q = *p;

They also encourage a programming style that, as it turns out, is reckless. Most of the buffer overrun bugs that created terriblesecurity vulnerabilities were due to code like this.

In my own practice, I observed that when I used ++ and --, my code tended to be too tight, too tricky, too cryptic. So, as a matter ofdiscipline, I don't use them any more. I think that as a result, my coding style has become cleaner.

Bitwise OperatorsJavaScript has the same set of bitwise operators as Java:

& and| or^ xor˜ not>> signed right shift>>> unsigned right shift<< left shift

In Java, the bitwise operators work with integers. JavaScript doesn't have integers. It only has double precision floating-pointnumbers. So, the bitwise operators convert their number operands into integers, do their business, and then convert them back. Inmost languages, these operators are very close to the hardware and very fast. In JavaScript, they are very far from the hardware andvery slow. JavaScript is rarely used for doing bit manipulation.

As a result, in JavaScript programs, it is more likely that & is a mistyped && operator. The presence of the bitwise operators reducessome of the language's redundancy, making it easier for bugs to hide.

The function Statement Versus the function ExpressionJavaScript has a function statement as well as a function expression. This is confusing because they can look exactly the same. Afunction statement is shorthand for a var statement with a function value.

The statement:

function foo( ) {}

means about the same thing as:

var foo = function foo( ) {};

Throughout this book, I have been using the second form because it makes it clear that foo is a variable containing a function value.To use the language well, it is important to understand that functions are values.

function statements are subject to hoisting. This means that regardless of where a function is placed, it is moved to the top of thescope in which it is defined. This relaxes the requirement that functions should be declared before used, which I think leads tosloppiness. It also prohibits the use of function statements in if statements. It turns out that most browsers allow functionstatements in if statements, but they vary in how that should be interpreted. That creates portability problems.

The first thing in a statement cannot be a function expression because the official grammar assumes that a statement that startswith the word function is a function statement. The workaround is to wrap the function expression in parentheses:

(function ( ) { var hidden_variable;

// This function can have some impact on // the environment, but introduces no new // global variables.})( );

Typed WrappersJavaScript has a set of typed wrappers. For example:

new Boolean(false)

produces an object that has a valueOf method that returns the wrapped value. This turns out to be completely unnecessary andoccasionally confusing. Don't use new Boolean or new Number or new String.

Also avoid new Object and new Array. Use {} and [] instead.

newJavaScript's new operator creates a new object that inherits from the operand's prototype member, and then calls the operand,binding the new object to this. This gives the operand (which had better be a constructor function) a chance to customize the newobject before it is returned to the requestor.

If you forget to use the new operator, you instead get an ordinary function call, and this is bound to the global object instead of to anew object. That means that your function will be clobbering global variables when it attempts to initialize the new members. That is avery bad thing. There is no compile-time warning. There is no runtime warning.

By convention, functions that are intended to be used with new should be given names with initial capital letters, and names withinitial capital letters should be used only with constructor functions that take the new prefix. This convention gives us a visual cue thatcan help spot expensive mistakes that the language itself is keen to overlook.

An even better coping strategy is to not use new at all.

voidIn many languages, void is a type that has no values. In JavaScript, void is an operator that takes an operand and returnsundefined. This is not useful, and it is very confusing. Avoid void.

Node's goal is to provide an easy way to buildscalable network programs

In the "hello world" web server example below, many client connections

can be handled concurrently. Node tells the operating system (through

epoll, kqueue, /dev/poll, or select) that it should be notified when a new

connection is made, and then it goes to sleep. If someone new connects,

then it executes the callback. Each connection is only a small heap

allocation.

var http = require('http');

http.createServer(function (req, res) {

res.writeHead(200, {'Content-Type': 'text/plain'});

res.end('Hello World\n');

}).listen(1337, "127.0.0.1");

console.log('Server running at http://127.0.0.1:1337/');

This is in contrast to today's more common concurrency model where OS threads areemployed. Thread-based networking is relatively inefficient and very difficult to use.See: this and this . Node will show much better memory efficiency under high-loadsthan systems which allocate 2mb thread stacks for each connection. Furthermore, usersof Node are free from worries of dead-locking the process—there are no locks. Almost

Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If youuse jQuery, you already know how to use Zepto.

While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. Thegoal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatileAPI, so you can concentrate on getting stuff done.

Zepto is open source software and is released under the developer and business-friendly MIT license.

Code Conventions for the JavaScript Programming LanguageThis is a set of coding conventions and rules for use in JavaScript programming. It is inspired by the Sun document Code Conventionsfor the Java Programming Language. It is heavily modified of course because JavaScript is not Java.

The long-term value of software to an organization is in direct proportion to the quality of the codebase. Over its lifetime, a programwill be handled by many pairs of hands and eyes. If a program is able to clearly communicate its structure and characteristics, it is lesslikely that it will break when modified in the never-too-distant future.

Code conventions can help in reducing the brittleness of programs.

All of our JavaScript code is sent directly to the public. It should always be of publication quality.

Neatness counts.

JavaScript FilesJavaScript programs should be stored in and delivered as .js files.

JavaScript code should not be embedded in HTML files unless the code is specific to a single session. Code in HTML addssignificantly to pageweight with no opportunity for mitigation by caching and compression.

<script src=filename.js> tags should be placed as late in the body as possible. This reduces the effects of delays imposed by scriptloading on other page components. There is no need to use the language or type attributes. It is the server, not the script tag, thatdetermines the MIME type.

IndentationThe unit of indentation is four spaces. Use of tabs should be avoided because (as of this writing in the 21st Century) there still is not astandard for the placement of tabstops. The use of spaces can produce a larger filesize, but the size is not significant over localnetworks, and the difference is eliminated by minification.

Line LengthAvoid lines longer than 80 characters. When a statement will not fit on a single line, it may be necessary to break it. Place the breakafter an operator, ideally after a comma. A break after an operator decreases the likelihood that a copy-paste error will be masked by

The Closure Tools project is an effort by Google engineers to open source the tools used in many of Google's sites and webapplications for use by the wider Web development community.

Web applications have evolved from simple HTML pages into rich, interactive applications that provide a great user experience.Today's web apps pose a challenge for developers, however: how do you create and maintain efficient JavaScript code thatdownloads quickly and works across different browsers?

The Closure tools help developers to build rich web applications with web development tools that are both powerful and efficient.The Closure tools include:

A JavaScript optimizerThe Closure Compiler compiles JavaScript into compact, high-performance code. The compiler removes dead code and rewritesand minimizes what's left so that it downloads and runs quickly. It also checks syntax, variable references, and types, and warnsabout common JavaScript pitfalls. These checks and optimizations help you write apps that are less buggy and easier to maintain.

A comprehensive JavaScript libraryThe Closure Library is a broad, well-tested, modular, and cross-browser JavaScript library. You can pull just what you need from alarge set of reusable UI widgets and controls, and from lower-level utilities for DOM manipulation, server communication, animation,data structures, unit testing, rich-text editing, and more.

The Closure Library is server-agnostic, and is intended for use with the Closure Compiler.

An easy templating system for both Java & JavaScript

YUI Compressor

According to Yahoo!'s Exceptional Performance Team, 40% to 60% of Yahoo!'s users have an empty cache experience andabout 20% of all page views are done with an empty cache (see this article by Tenni Theurer on the YUIBlog for moreinformation on browser cache usage). This fact outlines the importance of keeping web pages as lightweight as possible.Improving the engineering design of a page or a web application usually yields the biggest savings and that should always be aprimary strategy. With the right design in place, there are many secondary strategies for improving performance such asminification of the code, HTTP compression, using CSS sprites, etc.

In terms of code minification, the most widely used tools to minify JavaScript code are Douglas Crockford's JSMIN, the Dojocompressor and Dean Edwards' Packer. Each of these tools, however, has drawbacks. JSMIN, for example, does not yieldoptimal savings (due to its simple algorithm, it must leave many line feed characters in the code in order not to introduce anynew bugs).

The goal of JavaScript and CSS minification is always to preserve the operational qualities of the code while reducing itsoverall byte footprint (both in raw terms and after gzipping, as most JavaScript and CSS served from production web servers isgzipped as part of the HTTP protocol). The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a highercompression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin(becoming 10% after HTTP compression). The YUI Compressor is also able to compress CSS files by using a port of IsaacSchlueter's regular-expression-based CSS minifier.

CoffeeScript is a little language that compiles into JavaScript. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to exposethe good parts of JavaScript in a simple way.

The golden rule of CoffeeScript is: "It's just JavaScript". The code compiles one-to-one into theequivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript libraryseamlessly from CoffeeScript (and vice-versa). The compiled output is readable and pretty-printed,passes through JavaScript Lint without warnings, will work in every JavaScript runtime, and tendsto run as fast or faster than the equivalent handwritten JavaScript.

Latest Version: 1.6.2

sudo npm install -g coffee-script

Overview

CoffeeScript on the left, compiled JavaScript output on the right.

# Assignment:number = 42opposite = true

# Conditions:number = -42 if opposite

# Functions:square = (x) -> x * x

# Arrays:list = [1, 2, 3, 4, 5]

# Objects:math = root: Math.sqrt

var cubes, list, math, num, number, opposite, race, square, __slice = [].slice;

number = 42;

opposite = true;

if (opposite) { number = -42;}

square = function(x) { return x * x;};

list = [1, 2, 3, 4, 5];

Classes

Dart supports classes as a fundamental structural building block for

libraries and apps. Classes define the structure of an object, and

you can extend them to create more specialized definitions. New

features such as implicit interfaces and named constructors make it

easier to say more while typing less. Learn more about classes in

Dart.

Dart addresses issues with traditional web development languages while remaining easy to learn. Thanks to optional static types, Dart

scales from simple scripts to large apps. Learn more with the language tour, or read the language spec.
