JavaScript Tutorial – Get Or Remove Random Array Elements




Lesson Code: http://www.developphp.com/video/JavaScript/Get-or-Remove-Random-Array-Elements-Tutorial
Since JavaScript does not have built in methods for selecting or removing array elements randomly, we will demonstrate how to extend the Array object to supply it with those types of methods. The first example shows how to get a random array element without affecting the original array, the second example shows how to randomly splice an element from an array which removes the target item from the array. We also show how to extend the JavaScript Array object with these custom methods.

  1. I learned something productive in this video I had no idea how to do. Thank's Adam, continue the good work. Btw can you touch on a JS that would change an main image (such as a logo) though hover over or gallery slide shows? I would appreciate something like that because I feel my code is sloppy when making something like that.
