Let's take a deeper dive into the primitive data types because they'll be crucial to our work in JavaScript. We not only need to know what we're using, but the why is also important. Our primitives are the building blocks of the rest of the language: Booleans, numbers, and strings. The rest of JavaScript is built upon these primitive data types. We'll start with Booleans.
Booleans
The Boolean is possibly the simplest and most universal data type since it's inherently tied to the 1s and 0s of binary logic. In JavaScript, a Boolean is written simply as true or false. It's not recommended to use 1 or 0 for Boolean values, as they'll be interpreted as numbers and thus fail strict equality. Boolean values are a specific data type, as opposed to in Python, where, at the core of the language, Boolean inherits from a number.
Remember in Chapter 3, Nitty-Gritty Grammar, where we learned that almost everything in JavaScript is an object? The...
