How can I 'fire and forget' a JS function? (do not wait for return)

Question

I want to set a JS function running, but not wait for the response. The only way I can think to do it is:

setTimeout(function() {
    myFunc(); 
},0);

But that seems... inefficient at best. Any ideas?

Answer 1

You might want to look at webworkers

Answer 2

Why is that inefficient?

Also, don't forget that browser javascript is single-threaded. So, while your function runs, you will implicitly wait for it to return.

(async ajax calls may be an exception here)
