How to create an associative array in JavaScript literal notation

Question

I understand that there are no associative arrays in JavaScript, only objects.

However I can create an array with string keys using bracket

Answer 1

You can use Map:

var arr = new Map([
   ['key1', 'User'],
   ['key2', 'Guest'],
   ['key3', 'Admin'],
]);

var res = arr.get('key2');
console.log(res); // The value is 'Guest'
