Should You Learn JavaScript and CSS Before React?

React is a widely-used JavaScript library for building user interfaces. It has gained immense popularity among developers due to its simplicity, flexibility, and performance. However, when it comes to learning React, many beginners often wonder whether they should Learn JavaScript and CSS Before React.

In this blog post, we’ll explore the importance of learning JavaScript and CSS before diving into React and discuss the benefits it can bring to your React development journey.

Understanding the Foundation


JavaScript is the language that powers React. It provides the fundamental building blocks for creating dynamic and interactive web applications. Learning JavaScript before React is crucial as it enables you to grasp the core programming concepts. This includes variables, functions, loops, and conditional statements.

By understanding JavaScript, you can write cleaner and more efficient code in React, leverage its features effectively, and troubleshoot issues more easily.

Styling with CSS

CSS (Cascading Style Sheets) is the language used to describe the presentation and layout of a web page. It plays a significant role in web development and is an essential skill to possess alongside React.

While React offers its own styling options like inline styles or CSS-in-JS, having a solid understanding of CSS allows you to leverage the full power of CSS libraries and frameworks. These can create responsive designs, and effectively manage the visual aspects of your React components.

Seamless Integration

React works seamlessly with JavaScript and CSS; a strong foundation in both languages helps you understand how they integrate within React. By learning JavaScript and CSS beforehand, you’ll be better equipped to comprehend React’s syntax and concepts, understand the flow of data and state management, and implement dynamic interactions and animations in your applications.

Troubleshooting and Debugging

When building React applications, issues are bound to arise. Hence, having a solid understanding of JavaScript and CSS will help you diagnose and debug problems more effectively. You’ll be able to identify whether an issue is related to JavaScript logic, CSS styling, or React-specific concepts, which speeds up the debugging process and ensures smoother development.

Expanding Your Skill Set

While React is a powerful library, learning JavaScript and CSS provides you with a broader skill set that extends beyond React development. Because JavaScript is a versatile language used across various platforms, including front-end and back-end development, mobile app development, and server-side scripting.

CSS, on the other hand, is integral to web design and can be utilized in any web development project. By learning these foundational technologies, you’ll have the flexibility to explore other areas of web development and enhance your career prospects.


While it’s possible to jump into React without prior knowledge of JavaScript and CSS. It’s highly recommended to learn these foundational technologies first. Understanding JavaScript and CSS empowers you to utilize the capabilities of React fully. This will help you troubleshoot issues efficiently, and expand your skill set in web development. By mastering the basics, you’ll set a strong foundation for your React journey. You will be well-prepared to create exceptional user interfaces with this powerful library.
