Create a custom callback in JavaScript

Question

All I need to do is to execute a callback function when my current function execution ends.

function LoadData() 
{
    alert(\'The data has been loaded\');
          


        

Answer 1

Try:

function LoadData (callback)
{
    // ... Process whatever data
    callback (loadedData, currentObject);
}

Functions are first class in JavaScript; you can just pass them around.
