How to Create a Shallow Clone of a Value using Lodash ?

Shallow copy is the process of duplicating an object or array at the top level without copying nested objects or arrays.

Below are the possible approaches to creating a shallow clone of a value using Lodash.

Run the below command before running the code in your local system:

npm i lodash

Using clone() function

In this approach, we are using the clone() function of Lodash to create a shallow copy of the originalObj, making sure that changes made to res do not affect originalObj.

Syntax:

_.clone(value);

Example: The below example uses the clone() function to create a shallow clone of a value using Lodash.

JavaScript

const _ = require('lodash');
let originalObj = { 
    name: 'GFG', 
    age: 30 
};
let res = _.clone(originalObj);
console.log(res);

Output:

{ name: 'GFG', age: 30 }

Using assign() function

In this approach, we are using the assign function of Lodash to create a shallow copy of originalObj by assigning its properties to an empty object, making sure that res is an independent copy.

Syntax:

_.assign( dest_object, src_obj );

Example: The below example uses assign() function to create a shallow clone of a value using Lodash.

JavaScript

const _ = require('lodash');
let originalObj = { 
    name: 'GFG', 
    age: 25 };
let res = _.assign({}, originalObj);
console.log(res);

Output:

{ name: 'GFG', age: 25}
