React, a JavaScript library works with TypeScript or JavaScript, but whichever one clients choose has a different purpose. Statista shows that 62.3% of global developers use JavaScript while only 38.5% use TypeScript. However, knowing their differences helps make informed decisions before a mobile application development company starts work.
Discover a comprehensive comparison between using TypeScript or JavaScript with your React project to determine which programming language works better for the intended purpose and target audience, whether using React Native for mobile applications or React JS for web applications.
What Is React?
React is a JavaScript library that commonly uses the JavaScript programming language, whether developers use React JS for web applications or React Native for mobile applications. For example, React developers build Android and iOS applications using React Native with the JS or TS language.
React JavaScript code is more common, but a developer may use TypeScript components to add type definitions in the build process, which allows the app to function differently with added type safety. React Native or React JS can implement the benefits of either language.
What Is TypeScript?
TypeScript code evolved after the JavaScript programming language became more complex, allowing a developer to use the superset of JavaScript to write code that was easier to maintain and understand. TypeScript was more readable due to type annotations and improved type safety among other things.
React and TypeScript work for mobile and web development and include static typing and early build process error checking to reduce maintenance later. Additionally, TypeScript has a compiler that translates it into JavaScript code. TypeScript is also compatible with multiple platforms, even Node JS.
Benefits of Using TypeScript With React
Here’s a basic understanding of the benefits a developer can deliver when using the TypeScript language with React for web and native application development:
- Catch errors early in development for a higher-quality code
- Code completion and IntelliSense improve developer experience
- Simple syntax with readable code that’s easier to understand
- Can manage a complex codebase for large-scale projects
- Easy to understand and modify code is simpler to maintain
- Scale and grow projects or the return value with a scalable codebase
- Use strict type-checking for cleaner, more readable code
- Enjoy a higher provider value with customisable documentation
Disadvantages of Using TypeScript With React
Using React with TypeScript for the programming of client-side native or web applications could have some disadvantages for certain projects, including:
- A steeper learning curve for moderate developer experience
- It needs an additional build process step to compile TS to JS code
- It may require added tools and configuration compared to JavaScript
- More transpilation and type-checking can cause performance overhead
- Some edge cases make TypeScript incompatible with JavaScript
- TypeScript doesn’t have the same community support as JS
Use Case Example for Using React and TypeScript Code
An example of using TypeScript and React would be for a large-scale e-commerce platform with different components and functions. Developers can catch a “type argument” error early in development, benefit from good IDE support, and create a robust codebase that’s easier to maintain.
Reasons to Use React and TypeScript Code
Use TypeScript and React for the following reasons:
- Improved IDE Support
TypeScript is compatible with different code editors like Visual Studio Code, Sublime Text, and Atom, which improves the recommended code completion and error checking.
- Type Safety
Identify type-related issues during compile time rather than runtime, even identifying an error in React’s component props object, function, or properties.
- Easier Refactoring
TypeScript can simplify how a developer will rename the variables and functions in a large codebase by automatically updating the references.
- Seamless Documentation
A developer can create their own document with the code using JSDoc Comments, allowing simpler collaboration.
What Is JavaScript?
JavaScript code is often preferred for an interactive interface state in web application development. The popular programming language uses a component-based architecture and works wonders for embedded code in HTML docs, input type form validation, and dynamic content with animations.
Writing JavaScript with any JavaScript library like React JS or React Native results in an enhanced user experience. The rich ecosystem of libraries allows the seamless integration of core JavaScript syntax that enhances the functionality of applications. It also has strong community support.
Benefits of Using React JavaScript
The key advantage of using JavaScript with your React project is that the latter is a library of the former. Seamless integration is definite, and here are some more ways the combination may benefit a project:
- JavaScript is versatile enough for client-side and server-side programming
- It runs on multiple platforms and devices for cross-platform development
- It has an extensive community, ecosystem, and supported browser list
- JS is feature-rich with built-in functions and object libraries
- It doesn’t require extensive developer experience to learn to use JS
- JavaScript has comprehensive libraries, frameworks, and compatibility
- JavaScript and React use familiar components to use existing knowledge
- JS allows building apps faster because it doesn’t use strict typing
Disadvantages of Using React JavaScript
A React JavaScript project may have some disadvantages due to the complexity of the codebase, which is to blame for introducing bugs sometimes. Here are some potential drawbacks:
- JavaScript requires manual testing to identify errors
- Dynamic typing can cause an unexpected error due to flexibility
- JS is more prone to cross-site scripting (XSS) and injection attacks
- It uses asynchronous programming, which is hard to manage in complex applications
- It doesn’t use strict typing and makes debugging and maintenance hard in large projects
- JavaScript can face compatibility issues between certain browsers
Use Case for Using React JavaScript
An example of using JavaScript in a React project would be creating a small portfolio website. Developers can create interactive user interfaces with access to React-specific libraries, resources, and frameworks should they want a ready-made solution or a more interactive custom solution.
Reasons to Use React JavaScript
Use React and JavaScript for the following reasons:
- Seamless Integration
React is a JavaScript library that seamlessly allows the framework and languages to integrate, using the fullest functionalities in React applications.
- Component-Based Architecture
JavaScript’s component-based structure allows a developer to reuse code and design reusable components to speed up development and make it more maintainable.
- Rich Ecosystem and Libraries
JavaScript’s interoperability allows developers access to a vast array of libraries, frameworks, and tools to design a custom or ready-made solution.
- Enhanced User Experience
Improve how users experience the website or mobile application with dynamic or interactive user interfaces designed with a JS library.
Key Differences When Using JavaScript/TypeScript With React
Let’s discover each difference between using JavaScript and TypeScript with React Native or React JS to further narrow optional choices between the two languages. Some features add more value, while others may limit certain functions and reduce the language value.
What Is the Performance of React and TypeScript vs. JavaScript
React applications with TypeScript have improved performance because the React DOM interacts with TypeScript’s own document-object model (DOM) and static typing. TypeScript also uses an event handler to execute an application function based on the input type from users.
JavaScript’s performance is good due to the ability of familiar components and props to interact with each other between the React code framework and JS language. However, performance depends on the optimisation of complicated console objects, API integrations, and data classes.
Does React Work Better With JavaScript/TypeScript File Types?
TypeScript uses the .tsx extension for files that contain JSX (JavaScript XML syntax) with TypeScript code while JavaScript uses JSX syntax extension or file type that allows developers to write HTML-like components and elements in the code. JavaScript can use .js or .jsx as a file type.
Choosing JavaScript or TypeScript for input type, file type, prop types, or object types will vary, depending on project requirements and whichever file type definitions a client will prefer based on the use cases above. The .tsx extension is better for type safety and maintainability.
Does React With JavaScript/TypeScript Have Better Type Safety?
React with TypeScript has built-in safety for types to reduce type errors and clarify type declarations. TypeScript uses static typing with a built-in type checker. TypeScript types include boolean, string, array, enum, tuple, and unknown, but in some cases, the type declaration isn’t known.
TypeScript has improved safety for variables and object types and can be used to add type definitions to a JavaScript codebase. For example: developers will use the following command to install the latest version of type definitions: npm install @types/react @types/react-dom.
Is it Better to Maintain React With JavaScript or Typescript?
Using TypeScript with a React project makes code easier to maintain, read, and understand, improving maintainability. React developers use improved type information to declare defined objects and props. The simple construct makes the code easier to maintain but requires lib to interact with the React DOM.
JavaScript is harder to maintain, understand, and change by default. Some complexity examples include how JavaScript has a reducer function that allows a React developer to take the existing state and actions as arguments and return a new state result with a LAMBDA system to increase the return value.
What are Other React With TypeScript or JavaScript Technical Variables?
Here are more parameters to consider for differences between using JavaScript or TypeScript with React components and properties:
- Syntax Difference
TypeScript can use JSX for declarative UI components and is a superset of JavaScript while JavaScript only uses the core JSX syntax.
- Tooling Difference
TS is more complex, requiring additional tooling and configuration while JS works with basic text editors.
- Interoperability
JS is compatible with all other JS frameworks, but TS has some edge cases where it isn’t compatible.
- Type Definition Difference
JS uses prop classes or props to check types during the run time while TS uses TypeScript interfaces to check types during compile-time.

React TypeScript and React JavaScript FAQs
Is TypeScript with React suitable for small projects?
Smaller projects that require ready-made features created for a React project would better assume the written JS language. TypeScript is more complicated to write and install, even though it has simpler maintainability as it can use string, array, or even boolean coding structures in a static style of coding.
Is React JavaScript suitable for large projects?
JavaScript is better for smaller projects versus the new language, TypeScript. However, determine whether the JS language and seamless interoperability may benefit compatibility with a certain browser, render an API during events, or reduce runtime errors by checking elements during operations. You may also prefer the method of adding JS for larger projects to enhance the experience for users.
Is JavaScript or TypeScript better for React project development?
It depends on the purpose and project requirements. For instance, improved user interfaces increase the default value of using JS with React, whereas TypeScript can explicitly and correctly provide types for context, commands, loading, and usage, adding to the initial value of a const app or theme. Determine which values light the road to success for your React project.
Must I learn TypeScript for React projects?
Any React project using the following code requires some learning. TypeScript is more complex. For instance, the child component (children) in React is seen as a regular prop. Developers must define children thoroughly to ensure React components run smoothly. The language requires a steeper learning curve, especially for declaring objects and writing JavaScript documentation.
