Object key quotations: best practice?

Given that JSON objects list object keys with quotations, does it help in any way to do this in your normal JavaScript code? Or is the rule of thumb always to write your JavaScript objects without quotations around the keys as Andrew suggests in the video?

:point_right: Objects can contain many things, JSON only contains strings.

In JSON, both the keys and values are always strings. But JavaScript object literals have identifier names and values which can either or both be strings or other things. So the components of your JavaScript object literals would not be enclosed in quotes unless they happened to be string literals.
