JavaScript equivalent of PHP’s die

Question

Is there something like "die" in JavaScript? I've tried with "break", but doesn't work :)

Answer 1

throw new Error("my error message"); 

Answer 2

You can only break a block scope if you label it. For example:

myBlock: {   var a = 0;   break myBlock;   a = 1; // this is never run }; a === 0; 

You cannot break a block scope from within a function in the scope. This means you can't do stuff like:

foo: { // this doesn't work   (function() {     break foo;   }()); } 

You can do something similar though with functions:

function myFunction() {myFunction:{   // you can now use break myFunction; instead of return; }}
