Lodash _.snapshot() Method

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.snapshot() method is used to snapshot or clone the given object deeply.

Syntax:

_.snapshot( obj )

Parameters: This method takes an object to create a deep clone.

Return Value: This method returns the cloned object.

Note: This will not work in normal JavaScript because it requires the lodash contrib library to be installed. The Lodash contrib library can be installed using npm install lodash-contrib –save.

Example 1:

Javascript

// Defining the lodash-contrib variable
var _ = require('lodash-contrib');

// The given object
var given_object =
  { "a": 100, "b": 200, "c": 300 };

// Using the _.snapshot() method
// to create the deep clone
var cloned_obj = _.snapshot(given_object);

console.log("Cloned Object: ", cloned_obj);

Output:

Cloned Object: Object {1: "a", 2: "b"}

Example 2:

Javascript

// Defining the lodash-contrib variable
var _ = require('lodash-contrib');

// The given array
var given_array = [5, 10, 15, 20, 25];

// Using the _.snapshot() method
// to create the deep clone
var cloned_arr = _.snapshot(given_array);

console.log("Cloned Array: ", cloned_arr);

Output:

Cloned Object: [1, 2, 3, 4]

Example 3:

Javascript

// Defining the lodash-contrib variable
var _ = require('lodash-contrib');

// The given string
var given_string = "GeeksforGeeks"

// Using the _.snapshot() method
// to create the deep clone
var cloned_string = _.snapshot(given_string);

console.log("Cloned String: ", cloned_string);

Output:

Cloned Object: GeeksforGeeks

Example 4:

Javascript

// Defining the lodash-contrib variable
var _ = require('lodash-contrib');

// The given number
var given_number = 789434;

// Using the _.snapshot() method
// to create the deep clone
var cloned_num = _.snapshot(given_number);

console.log("Cloned Number: ", cloned_num);

Output:

Cloned Object: 10000
