mixin source npm

_.mixin([object=lodash], source, [options])

Adds all own enumerable function properties of a source object to the destination object. If object is a function then methods are added to its prototype as well.

Note: Use _.runInContext to create a pristine lodash function to avoid conflicts caused by modifying the original.

Arguments

  1. [object=lodash] (Function|Object)

    The destination object.

  2. source (Object)

    The object of functions to add.

  3. [options] (Object)

    The options object.

  4. [options.chain=true] (boolean)

    Specify whether the functions added are chainable.

Returns (Function|Object)

Returns object.

Example

function vowels(string) {
  return _.filter(string, function(v) {
    return /[aeiou]/i.test(v);
  });
}

_.mixin({ 'vowels': vowels });
_.vowels('fred');
// => ['e']

_('fred').vowels().value();
// => ['e']

_.mixin({ 'vowels': vowels }, { 'chain': false });
_('fred').vowels();
// => ['e']
