People can disagree with me here but I think for something small, it's all preference. I switched to backend 3 years ago and any time I do any personal frontend work, I use Typescript because otherwise I don't know what anything is. More on reddit.com

The word compiler is used loosely here. I agree, it doesn't fit the definition of a compiler 100%. It will basically transform JSX to Javascript No, it's main purpose is to do static analysis and optimization using techniques used in traditional compilers. Effectively, this means developers can write React code without APIs like `useMemo` or `useCallback` for example. There might be other opportunities as well, like subscribing to partial context updates. Isn't it like Babel and Webpack combined? Webpack is something completely different. Babel calls itself a compiler as well. In fact, it is very likely that the React Compiler will be available as Babel plugin. EDIT: If we are pedantic about it, I would argue transpilers are a special type of compiler. As in all transpilers are compilers, but not all compilers are transpilers. More on reddit.com
