Question

Currently I check if sed object already exists as to not wipe it if it does, then create the object.

if (typeof result === 'undefined') {
    results = {};
}

It’s just that I come from using PHP where you don’t really have to declare things as much as you do in JS.

Though I tend to use JS objects as I use arrays in PHP, as a way to temporarily store information which I need to access further down in a script.

This wouldn’t work if certain values (e.g., 0, null, or false) should not be overwritten, but:

results = results || {};

This works because || returns the first value if it is truthy or the second otherwise. undefined, along with some other values partially listed above, are falsy, but objects are truthy.
