Question

I don’t know why this isn’t working. I thought I’ve seen this in use a dozen times but it appears that I looked at it the wrong way judging from this:

var array = ["dog", "cat"];
console.log(array["dog"]); // undefined, why?

Answer 1

var array = {dog: "dog", cat: "cat"};
console.log(array["dog"]); // defined, why?

What you have is not an associative array, it does not act as such. A JavaScript object acts as such. The object’s literals are {}, not [].
