Associative array in javascript
There are multiple programming supports array and arrays is having different types i.e

Javascript only use numbered indexes in arrays.

studentDetail[0] = "Code";
studentDetail[1] = "Grepper";

studentDetail[3] = 'Mumbai';
var x = studentDetail.length;     // studentDetail.length will return 4
var y = studentDetail[1];         // studentDetail[0] will return "Grepper"
