debugging - Programmatically stop JavaScript execution in Firebug

Question

I am currently debugging complex JavaScript code with Firebug. I am looking for a way to stop the JavaScript execution as if it was a breakpoint programmatically.

Example:

instructions ...
degugger.breakpoint(); // the execution stops here as if a breakpoint was
                       // manually set
other instructions ...

Answer 1

You can use the debugger statement:

// your JS code
...
// break here
debugger;

It works in all major browsers.
