  9. * Adds all own enumerable string keyed function properties of a source
  10. * object to the destination object. If `object` is a function, then methods
  11. * are added to its prototype as well.
  12. *
  13. * **Note:** Use `_.runInContext` to create a pristine `lodash` function to
  14. * avoid conflicts caused by modifying the original.

  19. * @category Util
  20. * @param {Function|Object} [object=lodash] The destination object.
  21. * @param {Object} source The object of functions to add.
  22. * @param {Object} [options={}] The options object.
  23. * @param {boolean} [options.chain=true] Specify whether mixins are chainable.
  24. * @returns {Function|Object} Returns `object`.
  25. * @example
  26. *
  27. * function vowels(string) {
  28. * return _.filter(string, function(v) {
  29. * return /[aeiou]/i.test(v);
  30. * });
  31. * }
  32. *
  33. * _.mixin({ 'vowels': vowels });
  34. * _.vowels('fred');
  35. * // => ['e']
  36. *
  37. * _('fred').vowels().value();
  38. * // => ['e']
  39. *
  40. * _.mixin({ 'vowels': vowels }, { 'chain': false });
  41. * _('fred').vowels();
