  Complete the solution so that it takes the object (JavaScript/CoffeeScript) or hash (ruby) passed in and generates a human readable string from its key/value pairs.
  
  The format should be "KEY = VALUE". Each key/value pair should be separated by a comma except for the last pair.
  
  Example:
  
  solution({a: 1, b: '2'}) // should return "a = 1,b = 2"
  */
  
  function solution(pairs) {
    return Object.keys(pairs)
      .map(function (value) {
        return value + " = " + pairs[value];
      })
      .join(",");
  }
