Create an array of numbers in the given range

JavaScript version

const range = (min, max) => [...Array(max - min + 1).keys()].map((i) => i + min);

// Or
const range = (min, max) =>
    Array(max - min + 1)
        .fill(0)
        .map((_, i) => min + i);

// Or
const range = (min, max) => Array.from({ length: max - min + 1 }, (_, i) => min + i);

TypeScript version

const range = (min: number, max: number): number[] => [...Array(max - min + 1).keys()].map((i) => i + min);

// Or
const range = (min: number, max: number): number[] =>
    Array(max - min + 1)
        .fill(0)
        .map((_, i) => min + i);

// Or
const range = (min: number, max: number): number[] => Array.from({ length: max - min + 1 }, (_, i) => min + i);

Example

range(5, 10); // [5, 6, 7, 8, 9, 10]
