ReactJS Tutorial: A Step-by-Step Guide To Learn React

Topics Covered

ReactJS Tutorial Applications 

ReactJS is a JavaScript library that provides a fast, lightweight, and modern way to execute code. Here are the most important applications of ReactJS you will learn in this ReactJS tutorial:

1. Creation of Dynamic Web Applications

Creating dynamic web applications requires a lot of complex coding. ReactJS makes this super easy by enabling HTML quotes and tags to render particular subcomponents.

2. Code Maintenance

One of the major advantages of ReactJS is the ability to reuse components. This makes it easier to manipulate and define the objects that are used, which in turn provides for better code maintenance.

3. Mobile App Development

ReactJS provides similar design patterns that facilitates the smooth transition of web applications to mobile application development. You can also build high-end UI apps for both Android and iOS systems.

What is React? 

React is one of the most popular front-end JavaScript libraries in the field of web development. It is mainly maintained by Facebook and a large community of developers. A number of large, established companies (Netflix, Instagram, Airbnb, to name a few) use it to build their user interfaces and UI components. Whether you’re new to ReactJS or just want a quick refresh on its core concepts, this ReactJS tutorial will give you an introduction to React fundamentals, its features and components.

React Props 

ReactJS follows a distinct approach to data flow and manipulation which can make it difficult to understand a number of concepts (props, state, etc.). This ReactJS tutorial will help you understand React Props, one of the most important concepts of ReactJS. The term "props" stands for "properties" and is used to pass data from one component to another. In this ReactJS tutorial, you will also learn about the React Props feature and understand the methodology to use it.

ReactJS State 

ReactJS State is another important concept of ReactJS. React State holds the data for a component. This component, in turn, returns the data contained within the state to the output. A component’s “state” can change over time. Whenever this happens, the component re-renders. In this ReactJS tutorial, you will learn about the basics of ReactJS State, the setState() method, and the differences between ReactJS Props and ReactJS. State.

ReactJS Components

ReactJS Components are the building blocks of any application created with ReactJS. It splits the user interface into independent parts, each of which can be processed separately. ReactJS Components allow you to reuse the user interface elements, which has made ReactJS so popular. In this ReactJS tutorial, you will learn about the different  types of ReactJS Components, nesting ReactJS Components and the lifecycle of React Components.

React with Redux 

Redux is a predictable state container for JavaScript apps. It helps to maintain the data flow and keep it organized as an application grows. In this ReactJS tutorial, you will gain a working understanding of Redux and its most basic concepts. There is also an added bonus in this ReactJS tutorial to help you create a simple ReactJS application with and without Redux to help you understand the difference in more detail. 

ReactJS Interview Questions

Since ReactJS is one of the most popular front-end technologies out there, more and more companies are looking for professionals with this skill. If you are preparing for a job interview, this ReactJS tutorial provides a comprehensive list of all the common ReactJS interview questions that are frequently asked in interviews. These interview questions are grouped into the following categories - basic interview questions, Component interview questions, Redux interview questions, Router interview questions and Styling interview questions.

Here’s What You Can Do Next

ReactJS is quickly becoming the developers’ go-to choice for building web applications, rising above its competitors Vue.js and Angular. Whether you’re a newbie or a developer looking to upskill, there’s a number of reasons why you should learn ReactJS. Simplilearn’s ReactJS Training Course will help you master the fundamentals of React including JSX, props, state, and events.
