If you are a front-end developer or just starting your web development journey, learning ReactJS is the best way to start. Not only is ReactJS popular and in demand by employers, but it will also make you a better developer overall. In this roadmap, we will cover all the basics of ReactJS so that you can hit the ground running.
What is ReactJS?
ReactJS is a JavaScript library for building user interfaces. It was created by Facebook in 2011 and has become one of the most popular front-end libraries in recent years. ReactJS is used by many large companies, including Airbnb, Netflix, and Dropbox. ReactJS allows developers to create reusable components that can be used in multiple places within an application. This makes code more modular and easier to maintain. In addition, React uses a virtual DOM, which makes it more efficient than other front-end frameworks when it comes to updating the UI.
Why should you learn ReactJS?
There are many reasons why you should learn ReactJS. First, as we mentioned, it is one of the most popular front-end libraries and is in high demand by employers. Second, learning React will make you a better developer overall. ReactJS forces you to think about code in a more modular way, which will be helpful regardless of the language or framework you use in the future. Finally, React is relatively easy to learn compared to other front-end frameworks. Now that we’ve answered the question “what is ReactJS?” and “why should you learn ReactJS?”, let’s move on to learning about its features.
Breaking the Roadmap Down into Parts
We have organized this roadmap into three parts:
- Learn React Fundamentals
- Learn Advanced ReactJS concepts
- ReactJS Resources
LEARN REACT FUNDAMENTALS
This part of the roadmap will teach you the basics of ReactJS. You will learn about the different concepts in ReactJS such as JSX, props, state, and lifecycle methods. By the end of this section, you will be able to create simple ReactJS applications.
- JSX
- Props
- State
- Lifecycle methods
JSX
JSX is a syntax extension of JavaScript. It is used to describe the UI of React components. JSX looks like HTML but it is not HTML. It is important to note that you can use JavaScript expressions inside JSX.
Props
Props are immutable pieces of data that are passed to React components. They are used to customize the behaviour of components. props are also used to make the code reusable.
State
State is mutable data that is managed by the component itself. State should be used sparingly as it makes the component difficult to reason about. When using state, always use setState() method to update the state.
Lifecycle methods
Lifecycle methods are the methods that get called at different stages of the component's lifecycle. These methods are used to initialize the state, update the state, and perform cleanup before the component is unmounted from the DOM.
LEARN ADVANCED REACTJS CONCEPTS
In this section, you will learn about advanced ReactJS concepts such as a router, Higher-Order Components (HOC), and Redux. By the end of this section, you will be able to create sophisticated ReactJS applications.
- Router
- Higher-Order Components (HOC)
- Redux
Router
React Router is a library that allows you to add routing to your React application. Routing is used to navigate between different pages in an application. React Router makes it easy to add routing to your React application with its declarative API.
Higher-Order Components (HOC)
A higher-order component is a function that takes a component and returns a new component. HOC is used to extend the functionality of existing components. They are also used to reuse code.
Redux
Redux is a predictable state container for JavaScript applications. It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test. Redux is used together with ReactJS to manage the state of ReactJS applications.
