If you’ve been toying around with web development or even just discovering it, you have probably heard people mention the phrase “React JS”. This is not just a fad. React is one of a few tools that has become immensely liked as a way to build modern, fast, and user-centric web interfaces. So what’s the deal?
React JS is a JavaScript library such as Vue JS or Angular, created by Facebook (now Meta) to build user interface components. Feel free to compare it to jQuery! In more traditional web development - you would code pages, one after another. In React, you can build these little reusable pieces that can fit together/be put together like Lego. Each module can do something different. The modularity provides you with many benefits including time saving, reduced code duplication, and tidier projects.
React has changed the game since it was released in 2013. Fast rendering with its virtual DOM and a huge community of developers support around it, let’s just say - there is a lot to love about React - and if you are in web development - you should probably take notice. It can be applied to everything from a simple to-do list to a full-blown social media platform. React just helps you do it faster and smarter.
If you want to stay relevant in this semi-digital ages, or to just make your web app feel responsive and slick or re-imagine the build of your frontend or simply want to check out what the buzz is all about: React JS is a great option.
Best React JS Features That Make Every Developer Use It
React is all the rage these days but it's also changing the development experience on the web. Let's take a look at some of the features that make it so appealing to developers of every age and ability.
First up is component-based architecture. This means you create independent reusable blocks of UI such as a buttons, headers, card, etc. that you can use across different pages or apps. This can really speed up development and keep your code organized and scalable.
Next is the virtual DOM. If you've ever tried to manipulate the DOM you know that there are performance hits when growing an app - React quickly changes notified sections of your web application without having to refresh the entire page. This speeds things up, and as a user, you have a smoother experience.
Don't forget about the tools! React Developer Tools (available in Chrome and Firefox) allow you to inspect and debug your components live in the browser. You can see props, state, and performance bottlenecks all at a glance.
React does a great job of easing the workload by providing patterns and tools that make life easier. If you prefer efficiency, reusability, and maintainable code, these features of React will suit you well.
What Makes React JS Unique is its Ecosystem and Community
Beyond the features that React has to offer, what truly makes React a great choice is its thriving ecosystem and community. Need help debugging something? Want to find a library to help with routing? Or state management? There will continually be a tool, a blog, or a developer available.
Libraries such as Redux, React Router, and Next.js all help you with React without starting from scratch. They give you out-of-the-box solutions for common problems, including global state management, page routing, and SEO. You can utilize the power of React to build your app without having to understand every detail of its operation, because you are leveraging community-based solutions on top of a stable foundation.
And, of course, React's ecosystem includes React Native, which expands your need to leverage React's power into mobile. You can build iOS and Android applications using techniques, skills, and component structure, similar to the procedure to build web apps. This is an incredible convenience, allowing your operations to be cost-effective, and consistent across both mobile platforms.
And of course, you have to recognize that it is backed by Meta, so it receives frequent updates and always improves. It will have stability for the foreseeable future, which is a huge deal when adopting a platform as a solution for large scale, or mission-critical applications.
Regardless of the development lifecycle you are in, whether duck-taping together your first app or you are scaling a SaaS product, React's ecosystem can provide you everything you need to move forward successfully.
Who’s Using React JS and Why You Should Too
You might be thinking, well, it all sounds good in theory, but does React work in the real world? The simple answer is yes. On the practical side, some of the world's largest tech companies use React to power their platforms.
Think about Facebook, Instagram, Netflix, Airbnb, Uber, and Dropbox—all of these companies are using React in production. These companies are in charge of millions of users, heavy amounts of data, and never-ending alterations to the UI that they have to constantly implement; React allows them to far more easily scale their platform while maintaining a great user experience.
React isn't limited to only the big guys. It doesn't matter if you are a solo developer, founder of a small startup, or part of a 10-person development team, React's increased flexibility complements many project types. If you plan to create single-page applications (SPAs), dashboards, websites, or eCommerce platforms, React is solo friendly with many possibilities.
If you're still unsure it's worth exploring because you're not a developer, you should still explore. It is an easy framework to learn as a beginner. Learning React is a reasonably workable learning curve; the documentation is complete, approachable for beginners, and an easy read. You'll start out with components, props, and state; you will gradually be building dynamic user interfaces.
Getting Started with React JS: Learning Tips & Final Thoughts
If you're reading this and still not sure whether learning React is worthwhile, let's finish this chapter by providing some encouragement and a few useful tips.
First, learning React is absolutely worthwhile. It is in-demand by employers, and development with React is more enjoyable when you learn the ins and outs. You also write cleaner, faster, and more organized code using React.
So, here's some tips for learning React:
- Start with the official React documentation. It is well-done, written, and beginner friendly.
- Build tiny projects (like weather apps, to-do lists, and calculators).
- Use online coding platforms (like CodeSandbox, StackBlitz, and Replit).
- Join communities online (like Reddit, Twitter, or Discord).
- Watch tutorials on YouTube or read developer blogs that take you through real use cases.
And React has excellent performance features (like code splitting, lazy loading, and memoization etc.) that will help you as your app get bigger too!
So, is React worth it? Yes, 100%. It is not just a good tool, it’s a career changer.
