I like TypeScript's syntax, but I think the way function types are declared is ugly. If you have a function from A to B, you have to declare its type as type MyFunction = (arg1: A) => B instead of type MyFunction = A => B Here's that syntax applied to the example from GP: function call<TS extends any[], R>(fn: (...args: TS) => R, ...args: TS): R { return fn(...args); } vs. function call<TS extends any[], R>(fn: ...TS => R, ...args: TS): R { return fn(...args); }
