Create an associative array with integer keys

Question

I need to create an associative array in javascript with an integer key as follows;

a["10"] = "ten";

but when i create an array, it puts the value to the 10th index of the array and it creates an array with the length 11. I want it to be a key value pair. I know this can be done by using objects but i need an array only.

Answer 1

JavaScript does not have associative arrays. The only way to do this in JavaScript is to use objects:

var a = {
    '10': 'ten'
};
