Last Updated on March 9, 2024 by Nasir Hanif

Scripting languages are essential for implementing any type of functional User Interface design. The two most popular languages in this category are Javascript and TypeScript.

A lot of frontend programmers are glued to the amazing features of JavaScript, and its effectiveness in enhancing a website’s HTML pages. However, there’s confusion in the air as many companies are now beginning to consider the demand for programmers with in-depth knowledge of TypeScript. Let’s take a look at the differences between these two, so we can educate yourself on which is better:

Differences between TypeScript and JavaScript

Even though TypeScript is a subset of JavaScript, there are several differences between them. We won’t talk much about what is javascript to keep the article as succinct as possible. Let’s delve right into the differences:

WeightIt’s a lightweight coding language that uses few system resources.It’s a coding language that’s designed primarily for light applications.
Frontend/BackendIt can be used at both the backend and frontend side of an application.It’s only suitable for the front end.
Extension.tsx and .ts.JS
InterfaceIts interface allows for interconnection with multiple applications. Its code needs to be compiled, and it allows for better code exploration.It does not have an interface for connecting with other applications. It does not need to be compiled.
SyntaxTypescript programs consist of Variables, Comments, Modules, Functions, Statements & Expressions.Statements here must be written in a Script tag before it works.
AnnotationsAnnotations are required to obtain optimum results in TypeScript.It’s not needed in JavaScript codes.
TimeRequires ample time to compileCode is executed immediately.

Now that you know the differences between both languages, you’ll likely have a preference already.


If you want highly reusable, consistent, and clean language, then typescript is your best bet. Experienced software development agencies like JayDevs use it for huge projects due to its speed, scalability, and security. Javascript on the other hand is best for small coding projects.
