Functions and their types

In TypeScript, functions are an essential part of the language. They allow developers to encapsulate code into reusable blocks, making it easier to write maintainable and scalable code. This tutorial will cover TypeScript functions and their types, including how to create functions with different parameters, return types, and more.

Introduction to TypeScript Functions

Functions in TypeScript are similar to those in JavaScript, but with the added benefit of being strongly typed. This means that you can specify the type of the parameters and the return value of a function.

Creating Functions in TypeScript

To create a function in TypeScript, you use the function keyword, followed by the function name, and then the parameters in parentheses. You can also specify the return type of the function after the parameter list and before the opening brace.
