Closest to the target

Problem

Write a function that takes two numbers, a and b, plus a target, and returns whichever of the two lands closer to the target: with 4, 9 and a target of 6 you return 4, because 4 is 2 short and 9 is 3 over. If both are the same distance away, return the bigger one.

The numbers can be negative.

Examples

• 4, 9, 6 → 4

• The second one wins

  1, 8, 7 → 8

• All negative

  -7, -2, -4 → -2

Besides these, the challenge has hidden tests that are revealed when you submit your solution.

You start with this

def closest(a, b, target):
    pass

function closest(a, b, target) {
}
