As a web developer, you're likely well aware of the crucial role that selecting the appropriate programming language plays in the success of your project.

Among the hottest ongoing discussions in the field of web development is the comparison between TypeScript and JavaScript. Although both come with their own set of pros and cons, the question remains - which one is the best fit for your project?

In this blog, we will give you a comprehensive comparison of TypeScript vs. JavaScript. 

You will learn:  

So if you are grappling with the dilemma of choosing between TypeScript and JavaScript for your project? Fret not, this blog is here to guide you toward an informed decision!

Moreover, we will explore DhiWise React Builder- The revolutionary web app development platform that supports both JavaScript and TypeScript

Join us as we embark on an exciting journey to unravel the ultimate winner in the epic battle of TypeScript vs. JavaScript!

What is TypeScript and JavaScript?

TypeScript and JavaScript are both scripting languages used for web development.


TypeScript is a superset of JavaScript that adds static typing and other features to the language. It uses concepts like types and interfaces to describe the data being used, which makes it easier to write more robust and maintainable code. TypeScript supports type checking and type annotations which makes it suitable for large-scale projects


JavaScript is a dynamic, interpreted language that is commonly used for front-end web development Unlike TypeScript, JavaScript is a weakly typed language, which means it doesn't recognize the type of variable until it's instantiated at runtime. 

Therefore, TypeScript has emerged as a preferable option for developers to write code that's more simplified, maintainable, and efficient.

The difference between TypeScript and JavaScript

TypeScript and JavaScript have their own strengths and weaknesses, and each is beneficial for different kinds of web projects. 

The following table provides a general comparison between typescript and JavaScript.

TypeScript JavaScript
It is designed to overcome the limitations of JavaScript. Introduced as the first programming language for the web to add interactivity to websites and web applications.
TypeScript code is first transpiled into JavaScript code by the TypeScript compiler, which checks the code for type errors and other potential issues. Then it can be executed in the same way as any other JavaScript program. It is a dynamically typed, interpreted language, which means that it is compiled and executed at runtime
Strongly typed language Weakly-typed language
Steep learning curve and additional complexity. Relatively low learning curve
Most suitable for larger projects Comparatively less suitable for larger projects

Under the hood choosing between TypeScript and JavaScript will depend on the project requirements. The one which fulfills those requirements adequately can be considered.

The other essential factor to consider when making a comparison between TypeScript and JavaScript is the advantages and disadvantages each one brings to the table.

Advantages of using TypeScript

1. TypeSupport for JavaScript

One of the main advantages of using TypeScript is that it adds type support to JavaScript. This means that developers can take advantage of static typing, allowing them to catch errors early on in the development process.

2. TypeScript Generics and other useful functions

TypeScript have Generics and several useful functions such as Type Annotations, Interfaces, Type Inference, Namespaces, and Classes making it a better choice for larger and more complex projects.

3. Rich packages and library ecosystem:

TypeScript also offers a rich package and library ecosystem which makes it easier for developers to develop and test applications. Since TypeScript is a superset of JavaScript, it is easier for developers who are already familiar with JavaScript to get up to speed. 

Overall, if you are looking for a language that can help streamline your development process and catch errors early on, TypeScript is worth considering.

Disadvantages of using TypeScript

While TypeScript is a powerful programming language, it comes with its fair share of drawbacks when compared to JavaScript.

1. Expensive to use than JavaScript

TypeScript requires an integrated development environment to configure and run the code. This can make it more expensive to use than JavaScript, which only requires a simple text editor. 

2. Not suitable for small-scale projects

TypeScript may not be suitable for small-scale projects, as its use can lead to extra expenses.

3. TypeScript is that it has a steeper learning curve than JavaScript

This makes it unsuitable for novice developers who may struggle with the increased complexity of the language. Additionally, TypeScript may introduce errors in the code due to its more complex nature. 

However, as compared to TypeScript, JavaScript offers more freedom for experienced developers, as it does not need a compiler or static typing. 

Is TypeScript better than JavaScript?

It's not accurate to say that TypeScript is "better" than JavaScript, as they serve different purposes and have different strengths and weaknesses.

TypeScript is a superset of JavaScript that adds optional static typing and other features to the language, making it easier to catch errors and maintain large codebases. It can be particularly useful for complex projects or teams with multiple developers.

JavaScript, on the other hand, is a widely-used programming language that runs in web browsers and on servers using Node.js. It's flexible, easy to learn, and has a vast array of libraries and frameworks available, making it a popular choice for web development.

Then When to Use TypeScript vs. JavaScript?

Ultimately, whether to use TypeScript or JavaScript depends on the specific needs and goals of your project. 

“If you value static typing, robust error checking, and scalability, TypeScript may be a better choice. But if you prioritize flexibility, ease of use, and a large ecosystem of libraries and frameworks, JavaScript might be the better option.”

Popular apps built with TypeScript and JavasScript

TypeScript is a superset of JavaScript that adds static typing, classes, interfaces, and other features to the language. Here's a table comparing popular apps built with TypeScript vs JavaScript:

App Name Built with Description
Slack TypeScript Communication and collaboration platform
Microsoft Visual Studio Code TypeScript Code editor
Facebook TypeScript Social networking app
Airbnb TypeScript Online marketplace for short-term home stays
Amazon TypeScript E-commerce platform
Asana TypeScript Project management tool
Basecamp TypeScript Project management and collaboration tool
Trello TypeScript and JavaScript Project management platform
LinkedIn TypeScript Professional networking platform
GitLab TypeScript Web-based Git repository management tool
Discord TypeScript Communication platform for gamers

As our gaze falls upon the realm of popular applications, it becomes apparent that TypeScript reigns supreme, with some of them even complementing it with JavaScript.

So, it’s worth mentioning that TypeScript transcends JavaScript as a superset, thereby rendering any JavaScript code legitimate TypeScript code, and enriching it with additional functionalities.

Key Takeaways for Web Developers

In summary, while TypeScript and JavaScript have distinct roles, they can be combined to create dynamic web applications. JavaScript offers a robust, object-oriented programming language for building interactive web pages, based on the flexible ECMAScript standard.

Meanwhile, TypeScript is a superset of JavaScript with additional features such as typed data structures, modules, and reusable code components, making it particularly useful for managing large projects with static type-checking.

Deciding on the right programming language for your app is like choosing the perfect tool for a specific job - it all depends on what you need to accomplish. That's why we recommend that developers master both languages to harness their individual strengths.
