Numbers and booleans are primitive types in JavaScriptprimitive because they consist of nothing more than a small, fixed number of bytes that are easily manipulated at the low levels of the JavaScript interpreter. Objects, on the other hand, are reference types. Arrays and functions, which are ...

JavaScript and TypeScript have two primitive values used to signal absent or uninitialized value:nullandundefined. These types are most useful in the context of functions, so we'll discuss them in more detail in a later module. Next unit: Exercise - enums ...
TypeScriptprovides some useful primitive types that you’ll be using every day. In this article, I’ll explain them, what they’re for, and the TypeScript-specific primitives. number The number type works as you expect in TypeScript, covering all the ways JavaScript allows you to represent ...

A primitive type has a fixed size in memory. For example, a number occupies eight bytes of memory, and a boolean value can be represented with only one bit. The number type is the largest of the primitive types. If each JavaScript variable reserves eight bytes of memory, the variable can...

looked at objects as something that could extend what could be expressed in JavaScript. With primitive objects, that’s what I’m trying to explore. There are still things we cannot add, like new operators or literal syntax, but still, with primitive objects, we could define new types of ...
