Access non-numeric Object properties by index?

Question

If I have an array like this:

var arr = [\'one\',\'two\',\'three\'];

I can access different parts by doing this:

console.lo

I went ahead and made a function for you:

 Object.prototype.getValueByIndex = function (index) {
     /*
         Object.getOwnPropertyNames() takes in a parameter of the object, 
         and returns an array of all the properties.
         In this case it would return: ["something","evenmore"].
         So, this[Object.getOwnPropertyNames(this)[index]]; is really just the same thing as:
         this[propertyName]
    */
    return this[Object.getOwnPropertyNames(this)[index]];
};

let obj = {
    'something' : 'awesome',
    'evenmore'  : 'crazy'
};

console.log(obj.getValueByIndex(0)); // Expected output: "awesome"
