Call setTimeout without delay

Question

Quite often see in JavaScript libraries code like this:

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

I would like to know why use such a wrapper

Answer 1

There are a couple of reasons why you would do this

• There is an action you don't want to run immediately but do want to run at some near future time period.
• You want to allow other previously registered handlers from a setTimeout or setInterval to run
