It is an open-source, component-based, front-end library responsible only for the application’s view layer. React gained popularity due to some of its salient features  - can be used for the development of both web and mobile apps, unidirectional data flow, reusable components, creation of dynamic applications, and many more. In our React tutorial, we cover all such features, explain what exactly React is and the benefits of using it, it’s components, state, and more. So start learning with our React tutorial, and broaden your knowledge and hone your skills now.

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.

Master the fundamentals of React—an important web framework for developing user interfaces—including JSX, props, state, and events with the React.js Training Course.

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.

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.
