Underscore.js _.snapshot() Method

0 0 1 minute read

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

Syntax:

_.snapshot( obj );

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

Return Value: This method returns a clone object.

Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed.

Underscore.js contrib library can be installed using npm install underscore-contrib –save.

Example 1:

Javascript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');  
var given_Object = { 1:"a", 2:"b" }; 
var obj = _.snapshot(given_Object);; 
  
console.log("Cloned Object: ", obj);

Output:

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

Example 2: This method works well for an array also.

Javascript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');  
var given_Object = [ 1, 2 ,3 ,4 ]; 
var obj = _.snapshot(given_Object);; 
  
console.log("Cloned Object: ", obj);

Output:

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

Example 3: This method works for strings also.

Javascript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');  
var given_Object = "zambiatek"
var obj = _.snapshot(given_Object);; 
  
console.log("Cloned Object: ", obj);

Output:

Cloned Object:  zambiatek

Example 4:

Javascript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');  
var given_Object = 10000; 
var obj = _.snapshot(given_Object);; 
  
console.log("Cloned Object: ", obj);

Output:

Cloned Object:  10000
