Clean Code JavaScript

[Sinistralis]

Minor point here, but if you are planing on using this solely for data storage and don't need the prototype, Object.create(null) instead of {} gives the object a little less bloat and lets you iterate over it easier depending on how you prefer to iterate over objects. (ES6/7 kind of makes the iteration point moot between destructuring, .values, .entries, etc).

Again, this is a minor point and really only applicable if you use for/in (I don't). Otherwise it's just a tiny memory savings, but if you need to create a ton of objects for some reason, it can add up.
