{{{jsc}}} is a command-line utility that allows you to run JavaScript programs outside of the context of a web browser.  It is primarily used as part of the test harness for validating the JavaScript portions of WebKit, but can also be used as a scripting tool.

{{{jsc}}} can be run in an interactive mode to test out JavaScript expressions, or it can be passed one or more files to run similar to invoking a Perl or Python script.

== Usage ==
=== Command Line Flags ===
{{{
Usage: jsc [options] [files] [-- arguments]
  -d         Dumps bytecode (debug builds only)
  -e         Evaluate argument as script code
  -f         Specifies a source file (deprecated)
  -h|--help  Prints this help message
  -i         Enables interactive mode (default if no files are specified)
  -s         Installs signal handlers that exit on a crash (Unix platforms only)
}}}

=== Built-In Functions ===
* {{{quit()}}} Quit the interpreter


== Examples ==
You can use {{{jsc}}} as a calculator:
{{{
$ ./jsc
> "hello"
hello
> 1 + 3
4
> 2 * Math.sin(32)
1.1028533624833812
> 2 * Math.floor(1.2)
2
> 2 * Math.ceil(1.2)
4
> 15.3 / 18 * 27.1 * (Math.ceil(1.3) * Math.exp(2.3) * Math.log (1.223) * Math.sin(32.22))

You can also test more complicated expressions:
{{{
> var add3 = function(arg) { return arg + 3; }
undefined
> add3(3)
6
> 
}}}
