TypeScript

In TypeScript, enums, or enumerated types, are data structures of constant length that hold a set of constant values. Each of these constant values is known as a member of the enum. Enums are useful when setting properties or values that can only be a certain number of possible values. This tutorial will explain the syntax used to create enum types, the JavaScript code that the TypeScript compiler creates under the hood, and a use case for enums in game development.

TypeScript fully supports the existing JavaScript syntax for functions, while also adding type information and function overloading as new features. Besides providing extra documentation to the function, type information will also decrease the chances of having bugs. In this tutorial, you will start by creating the most basic functions with type information, then move on to more complex scenarios, like using rest parameters and function overloading.

Generics are a fundamental feature of statically-typed languages, allowing developers to pass types as parameters to a type, function, or other structure. TypeScript fully supports generics as a way to introduce type-safety into components that accept arguments and return values whose type will be indeterminate until they are consumed later in your code. In this tutorial, you will try out real-world examples of TypeScript generics to make your code more re-usable.
