# jsc(1)

command-line JavaScript interpreter.

## NAME

jsc - command-line JavaScript interpreter.

## SYNOPSIS

**jsc** \[*options*\] \[*files*\] \[*-- arguments*\]

## DESCRIPTION

This manual page documents briefly the **jsc** command.

**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.

  Evaluate argument as script code.

- **-f**

  Specifies a source file (deprecated).

- **-h, --help**

- **-i**

  Enables interactive mode (default if no files are specified).

- **-p** *file*

  Outputs profiling data to a file.

- **-s**

  Installs signal handlers that exit on a crash.

- **-x**

  Output exit code before terminating.

- **--options**

  Dumps all JSC VM options and exits.

- **--dumpOptions**

  Dumps all JSC VM options before continuing.

- **--\<jsc VM option\>=\<value\>**
