How much of JavaScript do you really think you know? You probably know how to write functions, understand simple algorithms, and can even write a class. But do you know what a typed array is?
You don't need to know all of these concepts right now, but you will eventually need them later in your career. That’s why I recommend bookmarking this list, because chances are, you’ll encounter one of these topics, and then you’re gonna want a tutorial to fully understand it.
It’s important to note that this list was inspired from the following repository: https://github.com/leonardomso/33-js-concepts

2. Primitive Types
All types except objects define immutable values (that is, values which can't be changed). For example (and unlike in C), Strings are immutable. We refer to values of these types as "primitive values". —Source
