Question

How can I correct the following code?

var arr = [];
var name = "name";
var val = 2;
arr.push(val); //works , but not associative
arr[name] = val; //does not work
console.log(arr);

Answer 1

To make something like associative array in JavaScript you have to use objects.
​

var obj = {}; // {} will create an object
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);
