Should I learn JavaScript or ReactJS?

When trying to decide which programming language to learn, the choice between JavaScript and ReactJS can be overwhelming. While both are popular options for web development, each has its own advantages and disadvantages. This article will help you determine if learning JavaScript or ReactJS is right for you.

Understanding JavaScript

JavaScript is a high-level, interpreted programming language that is used to create dynamic web pages. It is one of the core technologies of the World Wide Web, along with HTML and CSS. JavaScript can be employed to add interactive elements to websites, such as menus, forms, animations, and more. Additionally, it is also used for server-side development on the Node.js platform.

Understanding ReactJS

ReactJS is an open-source JavaScript library created by Facebook in 2013. It is utilized to construct user interfaces (UI). With ReactJS, developers are able to create reusable components that can be shared across multiple projects. Additionally, it offers a virtual DOM which makes it simpler to update the UI without having to reload the page.

Which Should You Learn?

The answer depends on your goals and experience level in programming. If you are just beginning with web development and want to construct basic websites or web apps then JavaScript could be a logical choice as it is easy to learn and there are various resources available for learning it. However, if you wish to develop more advanced websites or applications with dynamic user interfaces then ReactJS might be a better fit as it offers more flexibility than plain JavaScript.

Learning Both

If you desire to improve your skillset as a web developer then learning both JavaScript and ReactJS could be worth considering. This way you can use both technologies together in order to build complex web applications with dynamic user interfaces. Knowing both languages will also make transitioning between projects easier and keep you up-to-date with new technologies as they become available in the industry.


Deciding whether or not to learn JavaScript or ReactJS can be difficult but ultimately comes down to your goals and experience level in programming. If you are just starting out with web development then learning JavaScript may be best option while those wanting more sophisticated website or applications should consider ReactJS instead. Ultimately, the ideal option could even be learning both languages so that you can stay ahead of industry trends and maximize your opportunities as a web developer!
