First, let’s define what are primitive types.Primitive types in JavaScript arestrings numbers (Number and BigInt) booleans (true or false) undefined Symbol valuesnull is a special primitive type. If you run typeof null you’ll get 'object' back, but it’s actually a primitive type....

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 ...

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 ...
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 ...
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...

JavaScript has five primitive types: Undefined, Null, Boolean, Number, and String. Each of the primitive types defines a range of values as well as literal representations of that type. To determine if a value is in the range of values for a particular type, JavaScript provides the typeof ...
