Choosing which language to use when developing an application with React can be a challenging task. Questions like “should I use JavaScript or TypeScript with React?” will immediately come to the mind of any developer. So, why does this matter and what is the difference between the two? Do the benefits of one outweigh the potential drawbacks of the other? These are all questions that need to be addressed when making this decision.
The main problem developers face when making this decision is to find out which language brings the most performance and efficiency to the development process – JavaScript or TypeScript. JavaScript, given its native support for React, can be seen as the obvious choice, but recent advancements to TypeScript and the introduction of better support for React have called that decision into question. JSSpecc, a JavaScript module that provides a comprehensive type-checking system for JavaScript, is becoming increasingly popular with developers and is now seen as an integral feature when building applications with React. The decision of which language to use is an important one and developers must examine the pros and cons of each language in order to make the best choice.
In this article you will learn about the differences between JavaScript and TypeScript and the advantages of each in the context of React application development. It will include a discussion of the pros and cons of the two languages, an explanation of which language is best suited for React application development, and more. The article will provide a detailed comparison of the two languages and the developer will gain a deeper understanding of their options when choosing a language for their application. Finally, the article will discuss the best practices for using each language and the importance of using a reliable and comprehensive type-checking system.


JavaScript ( JS ) is a programming language that is supported by most modern web browsers and is mainly used to create interactive websites and web-based applications. It is an interpreted language, meaning that code is read line by line and executed on the fly.
TypeScript is a superset of JavaScript that adds optional type safety and other features for large-scale development. It is a strongly typed language, meaning that it can check references such as functions and objects for compatibility with its type system.
React is a JavaScript library for building user interfaces and is developed by Facebook. It was designed to help developers create large web applications that use data that changes over time.
Given their differences in type-safety, JavaScript and TypeScript can be used together with React to create web applications. JavaScript offers developers the ability to create quick and dirty applications without having to worry about type-safety. TypeScript offers developers the ability to create larger applications that can more easily be debugged and refactored. The two languages can be used together to create powerful web applications with less code. For instance, TypeScript can provide type-safety to functions and objects that have been developed in JavaScript.
When deciding whether to use JavaScript or TypeScript with React, it is important to weigh the advantages and disadvantages of each language. JavaScript is generally seen as a fast and easy way to develop web applications, while TypeScript is seen as a more robust and powerful language that can be used to create larger applications. It is up to the developer whether developers prefer the fast development of JavaScript or the type-safety of TypeScript.

Introduction to React

Introduction to React
React is a popular JavaScript library for building user interfaces and creating rich web applications. It provides a declarative and efficient way to develop web applications, allowing developers to create meaningful UI components quickly and maintain them easily. React components are written in the JSX language, which combines XML syntax and JavaScript code.
Advantages of React


React is extremely easy to learn and implement. Everything is described in plain JavaScript rather than proprietary concepts. This has made React quite popular with web developers who are looking for a simple way to build and deploy applications.

Faster Development

React helps developers to build applications quickly and efficiently. It utilizes a component-based system that allows developers to quickly add components, modify components and reuse components. In addition, the codebase of React is relatively small, which reduces the development time.

Performant Rendering

React helps developers to optimize performance with its virtual DOM. The virtual DOM is an in-memory data structure, which makes it easier to update the UI without re-rendering the entire page. This makes it possible to reduce page load time, making user experience faster and more enjoyable.

  • React is simple and easy to learn.
  • React enables faster application development.
  • React provides efficient and performant rendering.

Advantages and Disadvantages of JavaScript and TypeScript

The debate between JavaScript and TypeScript for React development is long and ongoing. While both have their own advantages and disadvantages, the decision between them cannot be made without considering certain criteria. This article will compare and contrast the primary features of the two languages and consider each option’s performance, scalability, and readability.


JavaScript is widely regarded for being a fast and reliable language, though Code complexity and quality of code can be an issue. TypeScript offers features such as type checking, which allows for easier debugging and clearer code. Furthermore, TypeScript code can be compiled down to JavaScript, allowing you to enjoy some of the benefits of type-safety while still getting the speed of JavaScript.


TypeScript is usually more scalable than JavaScript, thanks to it’s enforcement of strong typing and other features that support larger software engineering projects. As TypeScript is more widely adopted, there are more resources available to help with development in the language. Additionally, TypeScript code can make other developers’ lives easier by providing them with an easy-to-understand interface.


JavaScript can be difficult to read, as variable and function names are left up to the discretion of the developer, and the syntax can be difficult for new developers to understand. TypeScript forces developers to use code that is consistently readable because of its type checking and variable naming conventions. This makes maintenance and refactoring of code easier.
Ultimately, when choosing between JavaScript and TypeScript for React development, developers should take into consideration the performance, scalability and readability of both languages, as well as their own skill set and experience. Each language offers its own advantages and disadvantages, so it’s important to weigh the pros and cons before making a final decision.

Making a Decision between JavaScript and TypeScript with React

React is a popular JavaScript library used for developing web applications. It offers a number of features such as speed, performance, and flexibility, making it an attractive option for many developers. However, when building React applications, developers have the choice of using JavaScript or TypeScript. While both are powerful options, there are pros and cons associated with each, and understanding these differences can help developers make an informed decision.

Benefits of JavaScript in React Development

JavaScript is familiar to most developers and provides a quick and simple way of creating applications. It also offers the possibility of using existing code, allowing developers to build on existing libraries and frameworks. Furthermore, the language requires less setup than TypeScript and is often more straightforward, making it ideal for those who want to get an application up and running quickly.

Advantages of TypeScript in React Development

TypeScript is a typed superset of JavaScript, meaning it keeps the same syntax as JavaScript but adds additional features, primarily type safety. This makes TypeScript ideal for large applications, as it offers better support for managing code and allows developers to avoid common errors such as typos in dialling. In addition, the language provides better support for features such as asynchronous programming and more complex development scenarios.
Whether to choose JavaScript or TypeScript with React is ultimately a decision for developers to make. Understanding the benefits and drawbacks of each language will help developers make the most informed choice for their specific project. Both JavaScript and TypeScript offer their own advantages and disadvantages, so the decision should be based on the needs of the application and the skillset of the developer.
