TypeScript vs JavaScript

Explore the differences between TypeScript and JavaScript to understand why TypeScript's static typing and class-based syntax improve code scalability and reduce bugs. Learn how TypeScript addresses JavaScript's flexibility issues, making it a better fit for complex Ionic applications.

We'll cover the following...

For the novice JavaScript developer who might not be familiar with higher-level programming concepts such as classes and static typing, the benefits of TypeScript might not be immediately apparent.

To explain its benefits, we first have to realize that part of JavaScript’s strength, as well as its appeal and popularity, has always been its flexibility.

JavaScript’s flexibility

Let’s explore JavaScript’s flexibility through a simple example. If we wanted to define and create an object in JavaScript, we could choose any of the following approaches:

Approach 1: Using an Object() constructor

Javascript (babel-node)
var myObj = new Object();
