Examples
The following example shows code where a debugger statement has been inserted, to invoke a debugger (if one exists) when the function is called.
function potentiallyBuggyCode() { debugger; // do potentially buggy stuff to examine, step through, etc. }
When the debugger is invoked, execution is paused at the debugger statement. It is like a breakpoint in the script source.
