Implement a function clamp(number, lower, upper) to restrict a number within the inclusive lower and upper bounds.
value (number): The number to clamp.lower (number): The lower bound.upper (number): The upper bound.(number): Returns the clamped number.
// Within the bounds, return as-is.
clamp(3, 0, 5); // => 3
// Smaller than the lower bound.
clamp(-10, -3, 5); // => -3
// Bigger than the upper bound.
clamp(10, -5, 5); // => 5
