# About the JavaScript debugger [edit]

The Aptana JavaScript debugger provides you with numerous tools to help you closely examine and troubleshoot your JavaScript code. The JavaScript debugger uses its own Debug perspective (see About the Aptana Debug perspective) so that debugging tasks are separated from development tasks.

Before you can use the debugger, you will need to install it into your web browser. (See Installing the JavaScript debugger.) Currently, the debugger only works with Firefox, although it will be compatible with other browsers in the future.

Some of the features that can help you with your debugging are listed below:

- Use the Debug View to suspend a JavaScript thread.
- Add a breakpoint to your JavaScript code.
- Step into or over functions to navigate your code.
- Examine or change the value of a variable.
