JavaScript Objects: The Basics uses an unfamiliar term for Braces/Curly Brackets

In JavaScript Objects the term "figure brackets" is used repeatedly. The term results in zero relevant searches online. Formally, these are called "braces", informally they are referred to as "curly brackets". My suggestion is that one of these terms be used in place.

I would like to work on this and replace “figure brackets” with “curly braces” across the relevant sections. Will open a PR shortly.
