💻 Code
type Replace<T extends [...any], A, B> = {
[K in keyof T]: T[K] extends A ? B : T[K];
};
type ReplaceParams<T extends [...any],A,B>=(...args:Replace<[number,number],A,B>)=>any;//is ok
type ReplaceParams1<ARRAY extends [...any],A,B>=(...args:Replace<ARRAY,A,B>)=>any;//failed A rest parameter must be of an array type.
type ReplaceParams2<T extends (...arg:any)=>any,A,B>=(...args:Replace<Parameters<T>,A,B>)=>any; //failed A rest parameter must be of an array type.
type Remapped<T extends [...any]> ={
[K in keyof T]:T[K]
}
type SimpleCase<T extends [...any]> = (...args:Remapped<T>)=>any;//failed A rest parameter must be of an array type.🙁 Actual behavior
this was happend at latest version 5.2.2
and in the next version still no fixed
🙂 Expected behavior
quite sure tuple or array type can be passed to function rest pamaters. but remapped cant.this make replace certain type in parameters inpossible.
