Accessing JS array object using string

Question

var arr ={count:12,total:110};
console.log(arr.count,'',arr.total)   //12 110

but how to use like this

var c='count';
console.log(arr.c) //it's not similar to arr.count is there is any way to use this

How to access the array object by referring to the string?

Use bracket notation. `console.log(arr[c]) ` – Kavindra May 23 '18 at 07:58 — Kavindra, May 23 '18 at 07:58
Just a note: `arr` is not an array, it's an object. – Diasiare May 23 '18 at 07:59 — Diasiare, May 23 '18 at 07:59
