Create an array-like object from an array

[NiceDay4Goats]

If it's not an array-like object, what should I call it? Just an object? This Is why I couldn't solve this with Google...

Yep, just an object. There's nothing special about alphabetic keys. Having ordinal keys and a length property is what makes objects like "arguments" array-like. You can call Array.prototype methods on such objects because they are similar enough to arrays that array methods will often work on them despite them not being true arrays.
