海外TECH	DEV Community	React Important concepts you should know	https://dev.to/mojodev/react-important-concepts-you-should-know-a6o	React Important concepts you should knowReact important concepts can help you write cleaner code better code and optimize performance in this article I will share five React best practices you should know of Use Higher order Components HOCs A higher order component is an advanced technique in React that is used for supercharging and reusing components it takes a component as its argument and returns something elseconst EnhancedComponent higherOrderComponent WrappedComponent Whereas a component transforms props into UI a higher order component transforms a component into another component Properly understanding The UseEffect HookThis is one of the important things because if you do not understand this you will not get anywhere in React I can t emphasize enough the dangers of this hook you should properly understand this hook and how it relates to the usestate hook so you won t get a lot of infinite loops I like to think of this hook as middleware that runs after the component has been rendered initially I could talk more about it but that s the article for another day follow me if you want to read that Lazy loading images in ReactMultiple images can severely affect the performance of any application To compact this we avoid loading all the images at once With lazy loading we can wait until each of the images is about to appear in the viewport before we render them in the DOM Code splitting in React using dynamic import By default React apps render their final bundle in one giant file the good side of this is that it reduces the HTTP Request we might be making for different files but as your app grows bigger the file size increases this becomes a serious problem With code splitting React allows us to split a large bundle file into multiple chunks using dynamic import followed by lazy loading these chucks when we need them with React lazy Build Custom Hookswe have a bunch of important hooks available to us by default for us to use but to extend the component logic further it is important we build custom hooks Custom React hooks are an essential tool that let you add special unique functionality to your React applications Bounsit also important to understand the following Custom HooksReact s rules of hooksReact FragmentsReact context and context APIReact portalJSX RulesRefs and DOM In conclusionThose are the important concepts I think you should understand if enjoy it leave a reaction and follow me for more peace	2022-05-21 10:30:24
