海外TECH	DEV Community	JSX Element, React Node, React Element	https://dev.to/ridhoanshory/jsx-element-react-node-react-element-idi	JSX Element React Node React ElementI am currently migrating a React application to TypeScript So far this works pretty well but I have a problem with the return types of my render functions specifically in my functional components Cut a long story short I have these questions during my learning process What is the difference between JSX Element  ReactNode and ReactElement Why do the render methods of class components return ReactNode but functional components return ReactElement What is the difference between JSX Element  ReactNode and ReactElement A ReactElement is an object with a type and props type Key string number interface ReactElement lt P any T extends string JSXElementConstructor lt any gt string JSXElementConstructor lt any gt gt type T props P key Key null A ReactNode is a ReactElement a ReactFragment a string a number or an array of ReactNodes or null or undefined or a boolean A ReactNode is a ReactElement a ReactFragment a string a number or an array of ReactNodes or null or undefined or a boolean type ReactText string number type ReactChild ReactElement ReactText interface ReactNodeArray extends Array lt ReactNode gt type ReactFragment ReactNodeArray type ReactNode ReactChild ReactFragment ReactPortal boolean null undefined JSX Element is a ReactElement with the generic type for props and type being any It exists as various libraries can implement JSX in their own way therefore JSX is a global namespace that then gets set by the library React sets it like this declare global namespace JSX interface Element extends React ReactElement lt any any gt By example lt p gt lt ReactElement JSX Element lt Custom gt lt ReactElement JSX Element true amp amp test lt ReactNode lt Custom gt lt p gt Why do the render methods of class components return ReactNode but functional components return ReactElement they do return different things  Components return render ReactNode tl dr  It is a current TS type incompatibility not related to core React TS class component returns ReactNode with render more permissive than React JSTS function component returns JSX Element null more restrictive than React JSIn principle  render  in React JS class components supports the same return types as a function component With regard to TS the different types are a type inconsistency still kept due to historical reasons and the need for backwards compatibility Ideally a valid return type would probably look more like this type ComponentReturnType ReactElement Array lt ComponentReturnType gt string number boolean null Note undefined is invalidIf you guys have other thoughts leave a comment I ll update the post base on your solutions as well cheers	2022-03-12 00:12:52
海外TECH	DEV Community	Apple Event Recap	https://dev.to/littlegrapeguy/apple-event-recap-1c21	Apple Event RecapHello fellow tech nerds I know this recap is very late but for those of you who didn t hear Apple held their first event of the year on the th of March This event was a hardware focused event and therefore no software was unveiled The first announcements of the event were about Apple TV Apple just showcased their exclusive movies and exclusive streaming of baseball Then they moved on to their mid year refresh of the iPhone lineup They released two new colours for the regular and pro lineup The iPhone in Green and the iPhone Pro in Alpine Green Next Apple announced a refresh to the iPhone SE Apple entered this budget category a couple years ago and I think they did a fantastic job with their iPhone SE nd Generation From the chip to the camera The only problem this iPhone SE had was the battery life You would be lucky to be getting hours of screentime on that phone This year Apple included their flagship level chip and made improvements to the battery and build quality Now the iPhone SE is a full glass phone On paper this phone looks like an amazing budget phone that will get many software updates to come But we will have to wait for the reviews to start rolling out Note apple did bump the price up by USD from to Now the next products that Apple unveiled were the real meat of the presentation They introduced a new chip M Ultra Essentially this chip is two M Maxes fused together using what they called Ultra Fusion This new chip gives you CPU cores and GPU cores with GB of unified memory Now this begs the question what device is going to use this chip The answer to that is Mac Studio A new desktop computer for studios and professionals With the Mac Studio they also unveiled a Studio Monitor This studio monitor packs in a K Retina display P colour MP Ultra Wide camera High fidelity six speaker system studio quality mics and an A Bionic Chip With the new addition of this A chip this monitor on paper is more powerful than most phones on the market right now While all this does sound good Apple is going to charge you from USD for the Studio display and USD for the Mac Studio For all this Mac does pack in this price seems somewhat okay Let me know what you think in the comments Thanks for reading	2022-03-12 00:01:31
