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.

-e

Evaluate argument as script code.

-f

Specifies a source file (deprecated).

-i

-p file

-x

Output exit code before terminating.

--options
