Purpose of if(0){ //code }?

Question

Quick question. I just came across the following in a JS file:

if (0) {
    // code
}

What's the purpose of this if statement? Which cases would the code execute? It currently doesn't run the code in the if clause.

Answer 1

It looks like an artifact of the development process. Wrapping code like that gives you a quick, 1-character way to effectively comment out a block of code. It's quicker to toggle than a typical multi-line comment.
