as part of an expression in CoffeeScript, are converted into expressions
by wrapping them in a closure. This lets you do useful things, like assign

<p>
<span id="operators" class="bookmark"></span>
<b class="header">Operators and Aliases</b>
Because the <tt>==</tt> operator frequently causes undesirable coercion,
is intransitive, and has a different meaning than in other languages,
CoffeeScript compiles <tt>==</tt> into <tt>===</tt>, and <tt>!=</tt> into
<tt>!==</tt>.
In addition, <tt>is</tt> compiles into <tt>===</tt>,
and <tt>isnt</tt> into <tt>!==</tt>.
</p>
<p>
You can use <tt>not</tt> as an alias for <tt>!</tt>.
</p>
<p>
For logic, <tt>and</tt> compiles to <tt>&amp;&amp;</tt>, and <tt>or</tt>
into <tt>||</tt>.
</p>
<p>
Instead of a newline or semicolon, <tt>then</tt> can be used to separate
conditions from expressions, in <b>while</b>,
<b>if</b>/<b>else</b>, and <b>switch</b>/<b>when</b> statements.
</p>
<p>
As in <a href="http://yaml.org/">YAML</a>, <tt>on</tt> and <tt>yes</tt>
are the same as boolean <tt>true</tt>, while <tt>off</tt> and <tt>no</tt> are boolean <tt>false</tt>.

As a shortcut for <tt>this.property</tt>, you can use <tt>@property</tt>.

It's a little difficult to check for the existence of a variable in
JavaScript. <tt>if (variable) ...</tt> comes close, but fails for zero,
the empty string, and false. CoffeeScript's existential operator <tt>?</tt> returns true unless
a variable is <b>null</b> or <b>undefined</b>, which makes it analogous
to Ruby's <tt>nil?</tt>

It can also be used for safer conditional assignment than <tt>||=</tt>

The accessor variant of the existential operator <tt>?.</tt> can be used to soak
up null references in a chain of properties. Use it instead
of the dot accessor <tt>.</tt> in cases where the base value may be <b>null</b>
or <b>undefined</b>. If all of the properties exist then you'll get the expected
result, if the chain is broken, <b>undefined</b> is returned instead of
the <b>TypeError</b> that would be raised otherwise.

JavaScript's prototypal inheritance has always been a bit of a
brain-bender, with a whole family tree of libraries that provide a cleaner
syntax for classical inheritance on top of JavaScript's prototypes:

Instead of repetitively attaching functions to a prototype, CoffeeScript
provides a basic <tt>class</tt> structure that allows you to name your class,
set the superclass, assign prototypal properties, and define the constructor,
in a single assignable expression.

Heredocs can be used to hold formatted or indentation-sensitive text
(or, if you just don't feel like escaping quotes and apostrophes). The
indentation level that begins the heredoc is maintained throughout, so
you can keep it all aligned with the body of your code.

<b class="header">Extended Regular Expressions</b>
Similar to "heredocs" and "herecomments", CoffeeScript supports "heregexes" &mdash;
extended regular expressions that ignore internal whitespace and can contain
comments, after Perl's <tt>/x</tt> modifier, but delimited by <tt>///</tt>.
They go a long way towards making complex regular expressions readable.

<ul>
<li>
Ahh, whitespace. CoffeeScript's compiled JS now tries to space things
out and keep it readable, as you can see in the examples on this page.
</li>
<li>
You can now call <tt>super</tt> in class level methods in class bodies,
and bound class methods now preserve their correct context.
</li>
<li>
JavaScript has always supported octal numbers <tt>010 is 8</tt>,
and hexadecimal numbers <tt>0xf is 15</tt>, but CoffeeScript now
also supports binary numbers: <tt>0b10 is 2</tt>.
</li>
<li>
The CoffeeScript module has been nested under a subdirectory to make
it easier to <tt>require</tt> individual components separately, without
having to use <b>npm</b>. For example, after adding the CoffeeScript
folder to your path: <tt>require('coffee-script/lexer')</tt>
</li>
<li>
There's a new "link" feature in Try CoffeeScript on this webpage. Use
it to get a shareable permalink for your example script.
</li>
<li>
The <tt>coffee --watch</tt> feature now only works on Node.js 0.6.0
and higher, but now also works properly on Windows.

The CoffeeScript <b>0.9</b> series is considered to be a release candidate
for <b>1.0</b>; let's give her a shakedown cruise. <b>0.9.0</b> introduces a massive
backwards-incompatible change: Assignment now uses <tt>=</tt>, and object
literals use <tt>:</tt>, as in JavaScript. This allows us to have implicit
object literals, and YAML-style object definitions. Half assignments are
removed, in favor of <tt>+=</tt>, <tt>or=</tt>, and friends.

Downwards range comprehensions are now safe again, and are optimized to
straight for loops when created with integer endpoints.
A fast, unguarded form of object comprehension was added:
<tt>for all key, value of object</tt>. Mentioning the <tt>super</tt> keyword
with no arguments now forwards all arguments passed to the function,
as in Ruby. If you extend class <tt>B</tt> from parent class <tt>A</tt>, if
<tt>A</tt> has an <tt>extended</tt> method defined, it will be called, passing in <tt>B</tt> &mdash;
this enables static inheritance, among other things. Cleaner output for
functions bound with the fat arrow. <tt>@variables</tt> can now be used
in parameter lists, with the parameter being automatically set as a property
on the object &mdash; useful in constructors and setter functions.
Constructor functions can now take splats.

CoffeeScript now has a syntax for defining classes. Many of the core
