Question

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

Options:

A . It does nothing but a simple breakpoint

B . It debugs the error in that statement and restarts the statement's execution

C . It is used as a keyword that debugs the entire program at once

D . All of the mentioned

Answer: Option A

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.
