React 函数式组件 如果使用过jQuery/ RxJS 时的“链式语法”,其实就可以算做 FP 中 monad 的实践;而近年来大多数前端开发者真正接触到 FP,一是从 ES6 中引入的 map / reduce 等几个函数式风格的 Array 实例方法,另一个就是从 React 中的函数式组件(FC - functional component)开始的。 React 中的函数式组...
It could be anything from an index into an array, to a Dropbox file ID, to an IPFS URL, to a file path. It can be any type, or maybe it needs to be a string, I forget.Once you have a concept of a file handle, you can implement file pickers using the system hooks, and ...

The difference for the immutable...
