Lodash _.defaultsDeep() Method
Lodash _.defaultsDeep() method recursively assigns default properties. It is almost the same as the _.defaults() function. This method mutates the object.
Syntax:
_.defaultsDeep(object, [sources]);
Parameters:
- object: This parameter holds the destination object.
- sources: This parameter holds the source objects.
Return Value:
This method returns the object.
Example 1: In this example, we are using the -.defaultsDeep() method for setting the source’s value to the original object.
Javascript
// Requiring the lodash library const _ = require("lodash");// Given objectlet info = { Name: "w3wiki", password: "gfg@1234", username: "your_Beginner"}// Use of _.defaultsDeep() methodconsole.log(_.defaultsDeep(info, _.defaults(info, { id: 'Id97' }))); |
Output:
{
Name: 'w3wiki',
password: 'gfg@1234',
username: 'your_Beginner',
id: 'Id97'
}
Example 2: In this example, we are using the -.defaultsDeep() method for setting the source’s value to the original object.
Javascript
// Requiring the lodash library const _ = require("lodash");// Use of _.defaultsDeep() methodconsole.log(_.defaultsDeep( { 'x': { 'y': 20 } }, { 'x': { 'y': 10, 'z': 30 } })); |
Output:
{ 'x': { 'y': 20, 'z': 30 } }
