Enhanced for loop in 2D Array - JavaScript

Question

I created the following 2D array in Javascript

// Create basic linear array
var ImgArray = new Array(4);

// Do the 2D array for each or the linear array slo         


        

Answer 1

That's not an "enhanced for loop". You should not be iterating through Array instances that way anyway, at least not when you're treating them semantically as integer-indexed arrays.

Use your original

for (var i = 0; i < 4; ++i)

approach (and don't forget var). Also don't bother with

var ImgArray = new Array(4);

Just write

var ImgArray = [];
