Basically, you can specify a path to the property. In addition to Lo-Dash methods, wrappers also have the following Array methods: concat, join, pop, push, reverse, shift, slice, sort, splice Every method To deep merge two or more objects, you have to recursively copy all objects' own properties, nested arrays, functions, and extended properties to the target object. This way, when we copied the Object containing the nested Object, we have created a shallow copy of that object, meaning that the primitives found at the first level of the Object have values that are copied, thus when we change So when _.extend is used any change that might occur to nested objects in the objects that are being referenced, will also occur in the object that is extended.
