min and max

The minimum and maximum of a set of numbers can be calculated with Math.min() and Math.max():

let min = Math.min(5, 7);
let max = Math.max(3, 9, 2);

min receives the value 5 and max the value 9. The special: Both functions can be called with an arbitrary number of arguments.

Exercise

Write a function midrange, that calculates the midrange of 3 numbers. The midrange is the mean of the smallest and largest number.

Example: midrange(3, 9, 1) should return (9+1)/2 = 5.

+ Hint

function midrange(a, b, c) {
  let min = Math.min(a, b, c);
  let max = Math.max(a, b, c);
  ...
}

+ Solution

function midrange(a, b, c) {
  let min = Math.min(a, b, c);
  let max = Math.max(a, b, c);
  return (min + max) / 2;
}
