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 ...

You can use the debugger statement:
// your JS code
...
// break here
debugger;
It works in all major browsers.
