Returns an array of n-tuples of consecutive elements
Example:
const tips_arr = (n, arr) => n > arr.length ? [] : arr.slice(n - 1).map((v, i) =>[...arr.slice(i, i + n - 1), v]); console.log(tips_arr(2, [1, 2, 3, 4, 5])); console.log(tips_arr(3, [1, 2, 3, 4, 5])); console.log(tips_arr(5, [1, 2, 3, 4]));
Output:
[[1, 2], [2, 3], [3, 4], [4, 5]] [[1, 2, 3], [2, 3, 4], [3, 4, 5]] []
