exit - How to terminate the script in JavaScript?

Question

How can I exit the JavaScript script much like PHP's exit or die? I know it's not the best programming practice but I need to.

Answer 1

"exit" functions usually quit the program or script along with an error message as paramete. For example die(...) in php

die("sorry my fault, didn't mean to but now I am in byte nirvana")

The equivalent in JS is to signal an error with the throw keyword like this:

throw new Error();

You can easily test this:

var m = 100;
throw '';
var x = 100;

x
>>>undefined
m
>>>100
