  7. * Invokes the method at `path` of each element in `collection`, returning
  8. * an array of the results of each invoked method. Any additional arguments
  9. * are provided to each invoked method. If `path` is a function, it's invoked
  10. * for, and `this` bound to, each element in `collection`.

  12. * @static
  13. * @memberOf _
  14. * @since 4.0.0
  15. * @category Collection
  16. * @param {Array|Object} collection The collection to iterate over.
  17. * @param {Array|Function|string} path The path of the method to invoke or
  18. * the function invoked per iteration.
  19. * @param {...*} [args] The arguments to invoke each method with.
  20. * @returns {Array} Returns the array of results.

  23. * _.invokeMap([[5, 1, 7], [3, 2, 1]], 'sort');
  24. * // => [[1, 5, 7], [1, 2, 3]]

  26. * _.invokeMap([123, 456], String.prototype.split, '');
