Declare multiple variables in JavaScript

Question

I want to declare multiple variables in a function:

function foo() {
    var src_arr     = new Array();
    var caption_arr = new Array();
    var fav_arr     =          


        

Answer 1

No, your second statement will create four references to the same array. You want:

var src_arr     = [],
    caption_arr = [],
    fav_arr     = [],
    hidden_arr  = [];
