merge

_.merge(object, sources) # Ⓢ [Ⓣ][1] Ⓝ

This method is like _.assign except that it recursively merges own and

inherited enumerable string keyed properties of source objects into the

destination object. Source properties that resolve to undefined are

skipped if a destination value exists. Array and plain object properties

are merged recursively. Other objects and value types are overridden by

assignment. Source objects are applied from left to right. Subsequent

sources overwrite property assignments of previous sources.

Since

0.5.0

Arguments

1. object (Object): The destination object.
2. sources (Object|Object[]): The source objects.

Returns

(Object): Returns object.

Example

var object = {
  'a': [{ 'b': 2 }, { 'd': 4 }]
};

var other = {
  'a': [{ 'c': 3 }, { 'e': 5 }]
};

_.merge(object, other);
// => { 'a': [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }
