What are the components of React JS and how to use it

1. What are the components of React JS and What are the components of React JS and how to use it? how to use it? To begin with, React JS is a JavaScript library that is usually useful for creating user interfaces for single-page applications. In addition, it provides multiple extensions such as Flux and React Native, that supports the entire application architecture. It facilitates the easy creation of dynamic applications and results in improving performance. Moreover, it comes with reusable components that have their logic and control and they help in reducing the application's development time. Components Of React JS Components Of React JS Components stand for independent and reusable bits of code that are useful for the same purpose as JavaScript functions. In addition, they are useful in the initial rendering of the user interface along with management and handling of events. Moreover, they are also responsible for updating the user interface whenever there is a change in the internal stage. To further know about it, one can visit React JS Training in Noida. React JS consists of four types of components which are as follows. •Functional Components- These components do not have their state and they are functions that take in props and return JSX. Also known as stateless components, these are easy to read and debug and are useful in displaying information. •Class Components- They can possess a state and hold and manage their unique state. In addition, they have a separate rendering method to return JSX on the screen. •Pure Components- Pure Components only return a render function and are like better functional components. They are useful in providing optimization as they are quick and simple. •Higher-Order Components- This component helps in reusing component logic and it is a pattern that emerges from React’s compositional nature. These functions are responsible for returning a component and help in sharing logic with other components.

2. Features Of React JS Features Of React JS React JS is an SEO-friendly software tool and it comes with a great developer’s toolkit. This is a faster tool for rendering in comparison to other web frameworks. In addition, it eliminates the need for separate files for logic and markup. React JS uses JSX and makes the user experience better along with making the developer’s job less complex. Many institutions provide React JS Training in Delhi and one can enroll in them to learn it and start a career in it. Moreover, it follows a unique data flow and has a small learning curve as it consists of basic HTML and JavaScript concepts. •The Virtual DOM- It updates only the part of DOM that is required to update. It is a lightweight copy of the original Dom with all the characteristics of a real dom. In addition, it is much quicker than the original Dom and it updates itself whenever the update is made. •One-way Data Binding- It ensures that the whole application data flows only in one direction. In addition, it passes data from the parent component to

Moreover, these props do not go back to the parent component. •Components- React JS comes with various components and each one of them defines a view or a part of the view. In addition, it is easy to pass the data through the app as the component logic is written in JavaScript rather than templates. •JSX- JavaScript Syntax or JSX is similar to HTML and is a combination of JavaScript and XML. Above all, this is a simple syntax and it helps in easily writing components. •Conditional Statements- A user can use conditional statements inside the JSX. In addition, it is useful in displaying data in the browser on the basis of the condition. •Lifecycle Methods- These are a series of methods that are executed at multiple stages of execution and are useful in development. ShouldComponentUpdate, componentDidMount, componentWillUnmount and componentDidUpdate are some of its types. Conclusion Conclusion React JS is a JavaScript library that is useful for creating user interfaces for single- page applications. It consists of a few components such as functional, class, pure, and Higher-Order components. It provides a developer's toolkit and is faster for rendering as compared to other frameworks. Moreover, it is easy to learn and master, as it uses HTML and JavaScript concepts. In conclusion, React JS is an SEO- friendly tool that provides various features like virtual Dom, One-way Data Binding, Components, JSX, Conditional Statements, lifecycle methods. Etc.
