flow generic type for function [removed]arrow functions)

Question

I usually try to keep flow function types separate from their implementation. It\'s a slightly more readable when I write:

type Fn = string => string;
const a         


        

Answer 1

 type H = (input: T) => T;
    const h2:H<*> = i => i;   
    const h3:H<*> = i => i;   
    const hString: string = h3('apple');
    const hNumber: number = h2(7);
