Top 10 reasons why you should learn React right now by Mohammad Ayub

ReactJS is very easy to learn and more focused than some other JavaScript frameworks. ReactJs library is better equipped in dealing with search engine failure, creating a great SEO-friendly environment. Re-use of assets is very common among developers, who typically re-employ the same digital objects for better productivity. One can start with the finest components (checkbox, button, etc.), then move on to wrapper components comprising of tiny elements and move forward to the main root component. React is loaded with exceptional features creating better visual delight in terms of front-end designs as it eliminates the “Jquery” which is a code-heavy framework.

This is, maybe, the biggest reason why people are learning React. Being a popular, widely used, loved, and wanted framework, React has a huge job market. And even extends functional programming concepts with methods that return HTML instead of JavaScript objects. React JS is a JavaScript framework with 10 years of maturity and a huge community supporting its growth and development. Concurrent Mode is a set of new features that help React apps stay responsive and gracefully adjust to the user’s device capabilities and network speed.

By mastering Javascript, anyone could now potentially write the whole application. This is one of the reasons for Node becoming a trendy runtime environment to build applications. APIs have become the most common way in which frontend applications now communicate with the server and exchange data. React makes use of APIs to the fullest, most of the interactions with the outside world is done using APIs, and thus it helps in truly separating the frontend code with the backend. Unlike other JavaScript libraries, The Facebook React team built application state into React from the start.

In due time, you will be able to find it simply on reactjs.org. With that being said, you do not need to learn all of JavaScript first. Many JavaScript concepts can be learned at the same time you are learning React. Also, React is a base for many other popular frameworks like Next.js, GatsbyJS, and very recently Remix. Anti-Patterns are the practices that you should avoid using in the ReactJS applications. You should learn them along with the helpful patterns you should use.

• This gives the Game component full control over the Board’s data, and lets it instruct the Board to render previous turns from the history.
• The second approach is to replace the data with a new copy which has the desired changes.
• Here’s a great resource to help you learn about JSX in React.
• React is a JavaScript library that makes full use of JS’s capabilities.
• This will teach you industry-leading React best practices to create high-performance react apps.

You can use the Babel REPL to check what ES6 code compiles to. We’ll assume that you have some familiarity with HTML and JavaScript, but you should be able to follow along even if you’re coming from a different programming language. We’ll also assume that you’re familiar with programming concepts like functions, objects, arrays, and to a lesser extent, classes.

Tech Careers for Gamers

Though a simple front-end can be built using HTML, CSS, and JavaScript, to build a modern, complex front-end, we have to use powerful tools such as modern frameworks and libraries. React JS has been an important framework in developers’ toolkits for a decade now. But if you’re just starting your career, you’re probably better off not spending time learning it. In changing an object, developers only need to modify their state, make amendments for specific components.

React will compare its elements to the previous ones and figures out what is changed, and then it will update a part of the real DOM to keep it in sync with the virtual DOM. So, we need not worry about DOM in a browser if we use ReactJS. The virtual browser is better than the actual browser in case of user interaction. – If you just want to do one thing at this moment to kickstart your React.js journey, just go and join The Modern React with Redux course by Stephen Grider on Udemy. 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.

Facebook originally developed React because it was having challenges with code maintenance as its codebase and development team grew. The company eventually decided to release React as an open source project in 2013 and adoption steadily grew over the years. The most recent version of the library is React 18, which was released this year. If you want to jump in to learning React, you might not know what to do next, even after this article.

Noble Okafor is a technical writer and mobile developer with years of experience building optimized native and cross-platform mobile applications. He spends time writing articles on topics ranging from Javascript to mobile development, sharing his experience as a developer in the tech ecosystem. An important business consideration when building a web app is ensuring that it’s easy for potential users to find on Google and other search engines. Many companies implement search engine optimization to improve their rankings in search results, which in part involves the right web app architecture. React is generally considered SEO-friendly when developers use Gatsby.js or Next.s for server-side rendering because it makes the app faster and it’s easier for web crawlers to index. The combination of these technologies changed the landscape of web development.

Function Components

As you can see, learning React is a great choice for aspiring front-end web developers. It allows development teams to build web apps faster and maintain them more easily as they grow over time. It’s also a common prerequisite for many front-end web development jobs. Besides learning the basics of the React library itself, it’s important 5 Types of Enterprise Software and Why Theyre Worth the Investment to gain experience with some related libraries to become a proficient React front-end web developer. For example, state management and routing are essential for modern web apps, but require libraries like Redux and React Router. This is essential for becoming a well-rounded front-end web developer with React expertise.

There are various patterns you can use as solutions to common problems in React. 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.

Because React is the programming library behind Facebook’s website, it has to be extremely optimized and performant. Inside React the are components like the reconciler, optimizer and scheduler that make it so fast, but as developer, all we care about is it just works fast and reliably. Let’s expand our simple app by explicitly using what we call the useState React Hook. Let’s use that hook to create a count state and a method setCount, which will update count state. Let’s also create two buttons in our JSX rendering, one that increments count and one that decrements it.

Get updates and learn from the best

For example, many developers will use Node.js with React to utilize server-side rendering. It gives you the flexibility to write awesomely fast and clean code while using any other technologies that your project calls for. ReactJS is an open-source JavaScript-based user interface library.

For Beginners

It is a declarative, component-based user interface library. You can learn a lot about CSS on the CSS-Tricks site, and here’s a project-based tutorial to help you put basic CSS concepts into practice. But you should have a basic knowledge of the most-used tags and semantics. You Data Science Portfolio Tips to Build Good Data Science Portfolio can check out this HTML crash course for beginners and this HTML basics guide to get started. In this article, we will look at a complete roadmap to learn ReactJS. If you are thinking of starting ReactJS and looking to get a step-by-step approach, this article is for you.

We may think that Board should just ask each Square for the Square’s state. Although this approach is possible in React, we discourage it because the code becomes difficult to understand, susceptible to bugs, and hard to refactor. Instead, the best approach is to store the game’s state in the parent Board component instead of in each Square. The Board component can tell each Square what to display by passing a prop, just like we did when we passed a number to each Square. But you can compose and render custom React components too.

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. This gives the Game component full control over the Board’s data, and lets it instruct the Board to render previous turns from the history. Given an array of 9 squares, this function will check for a winner and return ‘X’, ‘O’, or null as appropriate.

Whereas in other frameworks like Angular, these tools come standard and you may not have to stop and think about them. Additionally, if you need to change or update state in many different parts of your app , there are Python-Crash-Course Python101 many competitors to Redux. Unlike Redux, these libraries do not require that you learn new concepts, such as reducers, actions, and so on. Redux is a library that helps us manage state in our React applications.

Single Page Applications, on the other hand, loads the webpage only once, and any further interaction with the app only loads the required data or performs an action on the server. This never reloads the whole application making it lighter on the server end as well as faster. In this article, we are going to talk about ReactJS and how it is increasingly becoming the most popular library for front end development. Leaning on a library, framework, or template isn’t cheating.
