how to wait until Array is filled (asynchronous)

Question

I have an array which is filled asynchronous and contains 28 items. I want to wait until the array is filled with all items.

function checkIfFinished(){
             


        

Answer 1

Try:

var timeout = setInterval(function() {
    if(checkIfFinished()) {
        clearInterval(timeout); 
        isFinished = true;
    }
}, 100);

This will call your check-function every 100 ms until checkIfFinished() gives true back to you.
