It is a good tutorial for beginners, after which they can advance to intermediate courses. YouTube is one of the best learning platforms in the world. For people who are looking to acquire free knowledge and make their life better, YouTube is one source that will never disappoint.

We create independent components that are reusable, self-contained, and isolated. Multiple components come together to build the application. As a beginner, you may not want to spend too much time in Babel or Webpack related configurations for your projects.

When you use React, everything is in Vanilla JavaScript, instead of some framework version of the language . React also gives you a lot of freedom to build a wide range of functionality and customization into your apps. Working in this framework helped me understand all sorts of Javascript concepts that simply weren’t getting into my head while I was using other frameworks.

If a component’s key changes, the component will be destroyed and re-created with a new state. We learned earlier that React elements are first-class JavaScript objects; we can pass them around in our applications. To render multiple items in React, we can use an array of React elements. Placing the history state into the Game component lets us remove the squares state from its child Board component. Just like we “lifted state up” from the Square component into the Board component, we are now lifting it up from the Board into the top-level Game component.

You will learn React.js quickly and never regret your decision. So if your goal is to find a high-paying job, then investing time and effort in React is worth it.

Whenever a new version is updated in React, it only increases the ease of use for us and the public APIs remain the same.

Companies need full-stack developers for their diversity of talents. Throughout this tutorial, we touched on React concepts including elements, components, props, and state. For a more detailed explanation of each of these topics, check out the rest of the documentation. To learn more about defining components, check out the React.Component API reference. The main benefit of immutability is that it helps you build pure components in React. Immutable data can easily determine if changes have been made, which helps to determine when a component requires re-rendering.

Reasons Why Every Front End Web Developer Should Learn React

Developers design views for each state of an application and React updates and renders components when data changes. React is an excellent addition to any Front End Web Developer’s skill set because it can help them increase their productivity. One of the core features of React is that it allows the user interface to be broken down into independent components. These components are reusable Roll your own JavaScript runtime and can be applied to separate pages and projects, which greatly reduces the amount of coding that’s required and speeds up development. You might be tempted to skip it because you’re not building games — but give it a chance. The techniques you’ll learn in the tutorial are fundamental to building any React app, and mastering it will give you a deep understanding of React.

At the end of all the transpilation, the code that you wrote is unrecognizable from the code that runs, making it much harder to debug. Alex Zito is a software developer and technology blogger with experience working in C# and JavaScript. React has a pre-rendering feature that helps in getting an SEO friendly platform in both SPAs or multiple page applications. Most of our applications require ranking to mark their presence, and Google achieves this ranking with the use of bots. SEO is a technique to boost user traffic where all the crawling and indexing is done by these Bots. The growth of React since its inception has been phenomenal.

Accommodating Different Learning Styles

Redux is still a great library, but first look to a library with a simpler API such as Zustand. As the most popular JavaScript library for building frontend applications, there has never been a better year to learn React than 2023. ReactJS allows the user interface logic to couple with rendering logic, events, handling state changes, and more. This coupling is to encourage the practices of building self-contained components. If you are someone who is just looking to get started and build something using React ASAP, then you can start with a project by

So if you are planning to learn React in 2023, then you should go for it. This makes it easier for beginners to pick up the Reac and work on existing React projects. React saves you time and money on development becauseit’s component-based. You can break down an interface into reusable components that allow you to build dynamic user interfaces. This taps into the current thinking behind ‘Design Systems’.

  • Vite provides a much faster experience in addition to requiring far fewer dependencies.
  • The Frontend is the interface where the users interact and the backend is where all the logic is done.
  • Then you can check out this overview of the Virtual DOM and how it works in React.
  • These are all the JavaScript concepts that, in my experience, you truly need to know to work with React at any level.
  • I am not comparing React with the Angular, Vue, or Svelte frameworks.

Now, more and more varied options exist, provided both by competing front-end frameworks and by browsers themselves. This framework is now the de facto mental model for web development, and the space has become saturated with choice. Despite competition from Vue.js and Angular, React is proving developers’ go-to choice for building exciting web applications.

Since the Square components no longer maintain state, the Square components receive values from the Board component and inform the Board component when they’re clicked. In React terms, the Square components are now controlled components. When the button is clicked, React will call the onClick event handler that is defined in Square’s render() method. Each Square will now receive a value prop that will either be ‘X’, ‘O’, or null for empty squares. Community created roadmaps, articles, resources and journeys for developers to help you choose your path and grow in your career. The React team is so focused on making the React library fast and stable, that in the latest release, version 17, there were literally no features added. The only change after updating to this latest version is apps bundle to much smaller size, they run significantly faster, and are more stable. That’s really something for the Facebook React team to be proud of. Because React is the programming library behind Facebook’s website, it has to be extremely optimized and performant.

Great Companies Need Great People. That’s Where We Come In.

This increases the job requirement of ReactJS skills in the world. React doesn’t require big lines of codes to program an application. A user writes small codes called components and combines them to form another component. Given React follow standard software development practices and patterns it was easier to pick it without much surprise. Once I understand component-based rendering and virtual DOM, the rest of the React is much easier to pick up. One of the major reasons why React is used widely is its performance.

I hope this has answered the most pressing question from many beginners and intermediate web developers about whether they should learn React.js or not. In this article, we discussed ten reasons why you should learn React in 2023. React is popular, it offers high-paying jobs, is easy to learn, and has many features.

Over time, ReactJS developers have found patterns they could use to help them stop reinventing the wheel. We should give users the choice of what theme they want – like light or dark – to use to help them feel comfortable when using your site or app. It is also helpful to bookmark a particular page or traverse back-and-forth in the application using the browser’s back button. You can learn all about React context in this beginner-friendly guide. Also, if you need to share some values between components that are not part of a hierarchy, you need a mechanism. Here’s a good starter guide on the DOM, or Document Object Model, and here’s one on how to manipulate the DOM.

Many developers choose to use JSX to create React elements because it’s very similar to HTML. This makes it even easier to make changes to React’s virtual DOM. One of the most common complaints about React is that it doesn’t quite handle State, so you’ll need to use some state management tool (ie. Redux, Flux, or MobX). One thing I do sorely miss about Angular is how lovely it is to not to have to stop and think about managing your state before you do literally anything.
