  @param {Array|Object} collection The collection to sample.
  @param {number} [n=1] The number of elements to sample.
  @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.
  @returns {Array} Returns the random elements.
  @example
  
  _.sampleSize([1, 2, 3], 2);
  // => [3, 1]
  
  _.sampleSize([1, 2, 3], 4);
  // => [2, 3, 1]
