Consider the following code snippet function f(o) { if (o === undefined) debugger; } What could be the task of the statement debugger?

It does nothing but a simple breakpoint
It debugs the error in that statement and restarts the statement’s execution
It is used as a keyword that debugs the entire program at once
All of the mentioned

Answer: Option 1

The debugger statement normally does nothing. If, however, a debugger program is available and is running, then an implementation may (but is not required to) perform some kind of debugging action. In practice, this statement acts like a breakpoint: execution of JavaScript code stops and you can use the debugger to print variable’s values.
