Here are some reasons why you should learn React to advance your career:
Easy learning curve
Lightweight virtual DOM
React uses a virtual DOM to optimize performance. Instead of updating the real DOM directly, React first updates a lightweight virtual representation of the DOM. React then compares the virtual DOM with the real DOM and only applies the necessary changes to the real DOM to update the page. This approach avoids expensive and unnecessary re-renders of the entire page, resulting in faster and more efficient updates.
The React library contains an extensive collection of reusable components that allow you to create dynamic web applications. The design interface of each React application combines components to form more complex ones, which together form a component tree. React’s component structure allows you to maintain a consistent appearance for your web application and continue to expand your code base by reusing those same components.
React applications are fast and reliable. This performance success occurs because of the various ways the framework’s applications are created.
React’s lightweight virtual DOM system processes user interface changes much more efficiently, as the application does not have to re-process the entire page each time a component’s status value changes. React will keep the virtual and real DOM in full sync, updating the latter when necessary as the user interacts with the web application. This puts less load on the browser and creates a pleasant user experience.
Since React is very flexible, you can optimize the performance of your web application by following React’s best practices. These practices will help you write better and more structured React code.
Easy debugging with React DevTools
React Developer Tools is a browser extension that helps you debug React applications. With its help, you can inspect React components within your web application to identify performance issues while running a development build. It is also possible to inspect component attachments, statuses, and hooks within the React component tree.
This makes it easy to debug your React applications, leaving you more time to focus on the core features of your application. React Dev Tools are available as an npm package for browsers like Safari.
Shorter development time
Using React to build web apps saves development time and helps you send your apps faster.
Since this is a very popular and robust framework, many APIs and open-source tools are available to speed development and help you scale through complex configurations. Reusing React components undoubtedly saves developers time, as they don’t need to waste time building the same components when they want to use them.
React also employs a declarative approach to managing state in web applications rather than an imperative approach. This means that it will manage the organization and state representation in your application, so you don’t have to implement detailed logic yourself.
Low development cost
When developing web applications, the development cost is directly proportional to the time spent creating the web application. The relatively short development time required to develop a standard-running React web application translates into lower costs.
In addition, learning React will allow you to move to React Native, a cross-platform mobile development framework. This means you can apply your standard React knowledge and turn your web apps into cross-platform mobile apps.
According to Statista, ReactJS was the web tool used second most among software developers worldwide in 2022 (the first was Node.js), and as many as 42.62% of developers said they were using ReactJS.
This large active community means enough support for React developers with issues or questions that need expert assistance. It also means that many open-source tools and libraries support React.
React is the top front-end framework chosen by many developers who create fast, reliable, and scalable web applications. Top companies like Facebook, Dropbox, Instagram, and Skype use React for its benefits.
