React for Beginners A React js Handbook for Front End Developers

JSX is a syntax that looks like HTML but also has the power of JavaScript. This syntax helps developers write UI logic with all necessary elements like data fetching, conditions, looping, expressions, etc. This approach is okay to get started but not sustainable. As a beginner, you may not want to spend too much time in Babel or Webpack related configurations for your projects. Let’s now focus on what you need to learn at the minimum to start enjoying React in practice. These are foundational pieces, so make sure to give enough time and hands-on effort to truly understand the concepts.

  • It is very easy to use, and it allows users to create reusable UI components.
  • You will implement a hangman game in React where users will guess a hidden word within a set of attempts.
  • To write JSX and have the browser understand this different syntax, we must use a transpiler to convert JSX to these function calls.
  • Additionally, the AI in the app will read each news, scroll by itself, and allow you to open news article links by voice control.
  • Learn how to create and interact with forms in React applications.

Many people, including myself, like React for its simplicity, flexibility, performance, usability, virtual DOM, components, and many other features. In this article, we will see reasons why you should learn React and how to get started with it. It’s the one course I wish I had when I started learning React. This element is a function that will allow us to update the value of the state variable .

Inside the Project Folder

We’ll get set up, explain the “hows and whys” behind the basic concepts, and build a small project which pulls data from an API so we can see everything in action. This guide will walk you through everything you need to know when getting started with React. This powerful composition model gives you an easy way to reuse components code throughout the application. When you don’t have the proper foundation, you’ll be a lot less efficient when building React applications. I am not comparing React with the Angular, Vue, or Svelte frameworks.

This makes the React author create what looks like a JavaScript version of HTML called JSX or JavaScript XML. As we can see, only the rendered time whose state changes gets repainted on every re-render. Likewise, we are not losing the input value when a state change occurs in the UI. In case you are still struggling with JavaScript, do not worry! You can read and code along as we write our React applications.

We’ve laid the foundations for building a fantastic React application and becoming a React developer. Hopefully, you’ve learned something new about React. It is worth saying that this is only a teaser of what we covered in the React series. Building React applications without using tools like Vite and CRA requires extra effort. We will install and configure a couple of libraries that the tools installed for us behind the scene.

You can easily get started to use reactjs by using the CDN javascript files, as shown below. It’s important to take a measured approach and concentrate on mastering the fundamentals of React and its syntax to conquer this challenge. Start by building small projects, such as a to-do list or a weather app, and gradually build up to more complex projects. This will help you to become more familiar with the concepts and syntax of React and make it easier to learn.

You need to know that there are more advanced ways to manage data, which include the Context API and libraries like Redux. But those introduce more complexity, and 90% of the times using those 2 ways I just explained are the perfect solution. A component either holds data or receives data through its props. In the case of the function argument, curly brackets are used as part of the object destructuring syntax.

I will give you some pointers in the last section about how to move forward. This book is especially written for JavaScript programmers who are new to React. To read more about JSX, check out the React team’s Writing Markup with JSX article. From this point there is a lot to learn about React and I wish you good luck as you continue on in your studies. If you enjoyed this article, you can support me by either buying me a coffee or following me on Twitter. According to the 2021 Stack Overflow developer survey, React surpassed jQuery as the most commonly used web framework with about 40.14% of the market share.

Web Building

Knowing how it works under the hood will help you with debugging. As an example, here’s a tutorial about styling your React apps with TailwindCSS. In this phase, you will start focusing on the completeness of the application.

React js, in some quarters, is often called a framework because of its behavior and capabilities to build full-fledged applications. However, it is technically a library; it requires more libraries to form complex solutions. For instance, we will need additional libraries to solve standard application requirements like routing, data fetching, etc. On the other hand, JavaScript frameworks like AngularJS, Vue.js, and Ember.js comes bundled with nearly everything to build a complete application.

Like the CRA, the src folder inside a Vite project also contains the working files. However, while the CRA uses the index.js file as the entry point, Vite uses main.jsx. The index.js file in the src directory will serve as the entry point to our application. The create-react-app CLI comes bundled with what an average developer would need to bootstrap a React application. It will include React and other third-party libraries we will need, including Webpack, and Babel, which lets us use JSX and modern JavaScript features.

Notice how we created a function called handleClick which alerts the message. Instead of using an inline function, we reference this function in our onClick property. If you trace through it carefully, you can see we are creating a div element, which has no props .

How does React use JavaScript?

I generally use separate files when the number of lines in a file grows too much. In particular, in a React component you can import other React components, and you can embed them and display them. In addition to defining some JSX to return, a component has several other characteristics.
