Given this:
type params = Parameters<(x: string, y:number)=>void>
In the pseudo code below how does one make fn to be (x: string, y:number)=>void, but using the params type?
type fn = (...params)=>void // type should be (x: string, y:number)=>void
CodePudding user response：
type fn = (...p: params)=>void
should work. Type the rest parameter with type params.
