JavaScript vs TypeScript: Choosing The Right Language

Let’s settle the debate between Javascript vs. Typescript. Developers consider the decision of Javascript or Typescript for new web or Node.js projects. Still, it is also an issue to consider for ongoing projects. If we look for definitions of both programming languages, JavaScript is a powerfully built high-level coding language with a JIT(just-in-time) compiler and provides dynamic typing.

javascript vs typescript

Before some more recent JS engines had server-side design and implementation, Javascript was only ever used on client-side servers. But Typescript is a Javascript with additional features primarily used in huge program-based applications.

Javascript Vs. Typescript

To understand which is better, let’s look at what both programming languages offer and contrast them.

Interface Support

When comparing Javascript and Typescript interfaces, Typescript is a more powerful type of OOP (object-oriented programming) language.

user interface

At the same time, Java script provides a high-level interpreting programming language. The user can connect with other applications in Typescript, but this feature is unavailable in JavaScript.

Server-side models

The downside of Typescript is that it mainly focuses on the client side, while javascript focuses on both the server and client sides.


Moreover, Typescript is a lightweight interpretation of coding language. But Javascript is not as light as Typescript as it designs and develops for huge applications.


Typescript is a superset of Javascript; it has additional features that solve the problems a user faces in Javascript. Like here, errors can be detected and corrected at the compile time itself, unlike Java, which does it during run-time since it is an interpretation of language.


A well-written code should constantly annotate to get the most out of Typescript, whereas, in Javascript, this is not mandatory.

Typing And Visibility of Codes

When we compare, Javascript is loosely typed as it supports only dynamic typing, not static, whereas Typescript supports static and dynamic typing and is thus strongly typed.


Typescript is more of an intuitive language, but Javascript is compatible and easy to write.

Generics and Prototyping

Javascript does not support features like prototyping and Generics, but Typescript not only helps them but also provides the creation of reusable components using these features.

Java is just a scripting language that is flexible to certain features and provides limited functionality to pages. At the same time, Typescript is an enhanced language with a stiff learning curve but has a smaller community base than Java.


Generally, Syntax refers to a set of rules and codes for programs, and every programming language provides its own set of Syntax. So, a typescript’s Syntax comprises various statements, modules, functions, expressions, variables, and comments.


But it’s a bit different in Javascript. Here, all the words are written inside a script tag that understands and executes all the programs written inside this tag.

Learning Curve and Setup

Javascript is easy to learn and code, while Typescript takes time to understand. So, before writing codes in Typescript, a programmer should be well-versed in the scripting knowledge of Typescript. Moreover, no build setup is needed in Java, while in Typescript, an npm package requires static typing.

Optional Parameters

In Javascript, functions cannot have optional parameters, while in Typescript, parts can easily have optional parameters. Moreover, Typescript supports ES3, ES4, ES5, and ES6, but this is different for JavaScript.

Once you’ve set up your development environment, you can start writing and executing JavaScript code directly within Visual Studio Code.


What is JavaScript?

JavaScript is a programming language for dynamic web content and interactive user interfaces.

What is TypeScript?

TypeScript is a superset of JavaScript that adds static typing and other features to enhance development.

What are the drawbacks of using TypeScript?

TypeScript can introduce additional complexity and requires additional time and effort to learn.

Can TypeScript code be run directly in a web browser?

No, TypeScript code must be compiled into JavaScript before it can be run in a web browser.

Can JavaScript code be converted to TypeScript?

Yes, JavaScript code can be gradually converted to TypeScript, and TypeScript allows for using existing JavaScript code.

Is TypeScript suitable for large-scale projects?

Yes, TypeScript is well-suited for large-scale projects because it provides increased type safety and better code organization.


It is entirely up to an individual to choose and believe that one language can surpass another or that the latter is superior. A fundamental programming language, JavaScript remains the first pick for many programmers due to its adaptability, extensive functionality, and enormous user base.

It is appropriate for small tasks requiring interactive desktop, smartphone, or online apps.
In contrast to this, TypeScript is a fantastic option for programmers when a sizable base requires. Even though it’s a different language, it has features like OOP fundamentals and Rich IDE integration, making it appropriate for complicated tasks and projects.

It can provide programmers with the features that JavaScript lacks. As a result, people have an alternative between them, which should depend on the task they are working on, including techniques for Changing CSS With JavaScript.
