Sum of powers

Giovanny Gongora

Calculates the sum of the powers of all the numbers from start to end (both inclusive).

const sumPower = (end: number, power: number = 2, start: number = 1) =>
  Array(end + 1 - start)
    .fill(0)
    .map((x, i) => (i + start) ** power)
    .reduce((a, b) => a + b, 0);
