Javascript range of integers with spread

[...Array(n).keys()]

[...Array(n).keys()] // [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Typescript type number range

type PrependNextNum<A extends Array<unknown>> = A['length'] extends infer T ? ((t: T, ...a: A) => void) extends ((...x: infer X) => void) ? X : never : never;

type EnumerateInternal<A extends Array<unknown>, N extends number> = { 0: A, 1: EnumerateInternal<PrependNextNum<A>, N> }[N extends A['length'] ? 0 : 1];

export type Enumerate<N extends number> = EnumerateInternal<[], N> extends (infer E)[] ? E : never;

export type Range<FROM extends number, TO extends number> = Exclude<Enumerate<TO>, Enumerate<FROM>>;
