_.mixin

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

Adds all own enumerable string keyed 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.

Since

0.1.0

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 mixins are chainable.

Returns

(*): 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']
