clampNumber

Clamps num within the inclusive range specified by the boundary values a and b.

If num falls within the range, return num. Otherwise, return the nearest number in the range.

const clampNumber = (num, a, b) => Math.max(Math.min(num, Math.max(a, b)), Math.min(a, b));

clampNumber(2, 3, 5) // 3
clampNumber(1, -1, -5) // -1
clampNumber(3, 2, 4) // 3
