Exploring Primitive Types
Explore TypeScript's primitive types such as number, string, boolean, undefined, and null. Understand their differences and how to handle them effectively in your code to improve type safety and clarity.
We'll cover the following...
Primitive types
What are primitive types? In programming, a primitive is a data type that is not derived from any other type and is not an object. They are the most basic types available in a programming language and are typically the building blocks for more complex data structures.
A few of the basic or primitive types that are available in TypeScript are numbers, strings, and booleans. While these represent some of the most basic and widely used types in the language, there are quite a few more, including undefined, null, unknown, and never.
Related to these primitive types, we also have some language features, such as conditional expressions and optional chaining, that provide a convenient shorthand method of writing otherwise rather long-winded code.
Undefined
There are a range of circumstances where the value of something in JavaScript is undefined.
