Author: Melissa Hovik (on 2016/12/18)

Write a function named repeat that accepts a string and a number of repetitions as parameters and returns the String concatenated that many times. For example, the call of repeat("echo...", 3) returns "echo...echo...echo...". If the number of repetitions is 0 or less, return an empty string.

Function: Write a JavaScript function as described, not a complete program.
