海外TECH	DEV Community	Introduction to ReactJS	https://dev.to/nehasoni__/introduction-to-reactjs-3553	Introduction to ReactJS What is React First of all React is not a JavaScript framework it s simply a javascript library developed by Jordan Walke that helps you to create User Interfaces UI React was first used in Facebook s newsfeed in and then later in Instagram WhatsApp by and released to the public in Today most of the applications are built using Model View Controller MVC architecture and in this MVC architecture React is the V that stands for view In ReactJS everything is a component and each component is responsible for outputting a small reusable piece of HTML code It is mostly used to build reusable components and it reduces the re rendering of the DOM with the help of Virtual DOM React Versions See different react versions here React Installation See installation steps here Prerequisite Before learning ReactJS there are certain prerequisites to keep in mind Top Skills You Must Know Before You Learn ReactJS Why ReactJS As there are many JavaScript frameworks available in the market like angular node jQuery but what ReactJS has done to the front end world that made it so popular and one of the most sought out options in the world of UI development Let s have a brief look into some ReactJS features JSX JSX stands for JavaScript XML It s an XML HTML like syntax used by ReactJS It extends the ECMAScript so that HTML like code can co exist with JavaScript react code This format is rendered to the normal browser Javascript by the pre processors such as Babel It is much faster than normal JS as it performs optimizations while translating to regular JS Virtual DOM Do you remember how Facebook s UI looked a few years back You had to reload the entire page for new updates repeatedly But now it s no longer required and this is the magic of ReactJS Re render everything on every update It sounds expensive but it s not React will make the browser render only if there are any differences and if there are no differences React will make the browser render nothing This makes the rendering super fast One way Data Binding In this method the data flows in only one direction i e the view will not get automatically updated when the data model is changed This feature gives you better control over your application Performance Owing to the Virtual DOM excellent state management and the component based architecture the performance of React surpasses or is on par with many of its competitors Native Support ReactJS also have a native version called React Native which offers the best of React world to the mobile app development platforms React Native supports the simultaneous building of apps in both Android and iOS platforms Fundamentals of ReactReact has exploded in popularity ー and for good reason Let s study the fundamental building blocks of React and understand things clearly Component As I already discussed that ReactJS is all about components Components make the task of building UIs much easier React allows you to break your page into independent building blocks that can be created maintained manipulated reused independently and then merged to construct the entire page React deals with two types of components Functional ComponentNo stateThere is no render method used in functional components Simple JS functionsMay take props as parameters and return the output to be rendered Example import React from react function App return lt div gt lt h gt Hello folks lt h gt lt div gt Class Component Also known as Stateful components because they implement logic and state It must have the render method returning HTMLMore complex and flexible but deprecatedExample import React Component from react import ReactDOM from react dom class App extends React Component render return lt div gt lt h gt Hello folks lt h gt lt div gt ReactDOM render lt App gt document getElementById root Props When building a react application the UI is divided into many smaller components Some of these components are re used in various parts of the application and to make these components effective props are used They attribute like entities in components which can be passed to the children components Props are immutable so we cannot modify them inside the child component Let s see how to pass the data with props from parent component to child component App jsimport React Component from react class App extends React Component render return lt div gt lt h gt Welcome to this props name lt h gt lt h gt this props name is one of the best blogging platform lt h gt lt div gt export default App Main jsimport React from react import ReactDOM from react dom import App from App js ReactDOM render lt App name Hashnode gt document getElementById app OutputDefault Props It is not mandatory that we always pass props from the parent component In this case we need to set up a default prop value to cover up Example App jsimport React Component from react class App extends React Component render return lt div gt lt h gt Welcome to this props name lt h gt lt h gt this props name is one of the best blogging platform lt h gt lt div gt App defaultProps name Hashnode export default App Main jsimport React from react import ReactDOM from react dom import App from App js ReactDOM render lt App gt document getElementById app OutputState The state is an updatable object that contains data and also keeps track of changes in the component States are mutable which means we can modify the data with the help of the setState method It is responsible for making components dynamic Whenever the state changes the setState schedules an update to a component associated with that particular state object ExampleApp jsimport React Component from react class App extends React Component constructor super this state readMore false this toggleReadMore this toggleReadMore bind this toggleReadMore this setState readMore this state readMore render return lt div gt lt h gt Welcome to Hashnode lt h gt this state readMore lt div gt lt h gt Hashnode is a free developer blogging platform that allows you to publish articles on your own domain and helps you stay connected with a global developer lt h gt lt button onClick this toggleReadMore gt Show Less lt button gt lt div gt lt div gt lt button onClick this toggleReadMore gt Read More lt button gt lt div gt lt div gt export default App Main jsimport React from react import ReactDOM from react dom import App from App js ReactDOM render lt App gt document getElementById app OutputComponents Life Cycle In ReactJS every component is undergoing lifecycle methods starting from its initialization Let s discuss component lifecycle methods in this section Initial Phase This is the phase from where the components start their journey Here a component contains the default Props and initial State This phase occurs only once and consists of the following methods a getInitialState b getDefaultProps The first method will get the initial state information and the second one will get the initial props needed for the component Mounting Phase After the initialization phase the instance of a component is created and the next step to be taken care of its mounting to the DOM ReactJS provides the following three methods for this a componentWillMount b componentDidMount c render The first method is called before the render method and if we are setting a state here it would not re render the component and the second is called immediately after a component gets rendered and placed on the DOM and the last method is defined in each and every component and responsible for returning a single root HTML node element Updating Phase This phase deals with the updates in the component which happens either due to a change in props or a change in state and it repeats again and again ReactJS provides the following five methods for this a componentWillRecieveProps b shouldComponentUpdate c componentWillUpdate d render e componentDidUpdate Unmounting Phase Finally in this phase the component instance is destroyed and unmounted from the DOM ReactJS provides the only one method for this a componentWillUnmount This method is called just before the component gets removed from the DOM ConclusionIn this blog I have introduced you to the main concepts of ReactJS and philosophies behind it In the next blog we will learn about react router You can find the ReactJS mini projects at my GitHub Repository Drop a star if you find it useful
