lodash.clone
Advanced tools
The lodash.clone package is a utility library that provides a method to create shallow copies of values. It is part of the larger Lodash library, which is known for its wide range of utility functions for common programming tasks.
Shallow Clone of Objects
This feature allows you to create a shallow copy of an object. The cloned object will have the same properties as the original object, but changes to the cloned object will not affect the original object.
const _ = require('lodash.clone');
const obj = { a: 1, b: 2 };
const clonedObj = _.clone(obj);
console.log(clonedObj); // { a: 1, b: 2 }
Shallow Clone of Arrays
This feature allows you to create a shallow copy of an array. The cloned array will have the same elements as the original array, but changes to the cloned array will not affect the original array.
const _ = require('lodash.clone');
const arr = [1, 2, 3];
const clonedArr = _.clone(arr);
console.log(clonedArr); // [1, 2, 3]
Shallow Clone of Nested Objects
This feature allows you to create a shallow copy of a nested object. Note that only the first level of the object is cloned; nested objects are still referenced.
const _ = require('lodash.clone');
const nestedObj = { a: { b: 2 } };
const clonedNestedObj = _.clone(nestedObj);
console.log(clonedNestedObj); // { a: { b: 2 } }
clonedNestedObj.a.b = 3;
console.log(nestedObj.a.b); // 3
The 'clone' package provides both shallow and deep cloning capabilities. It is more versatile than lodash.clone as it can handle more complex data structures, including circular references.
The 'rfdc' (Really Fast Deep Clone) package is optimized for performance and provides deep cloning capabilities. It is faster than lodash.clone for deep cloning operations but does not offer shallow cloning.
The 'deepcopy' package focuses on deep cloning and can handle complex data structures, including circular references. It is more specialized than lodash.clone, which only provides shallow cloning.
The lodash method _.clone
exported as a Node.js module.
Using npm:
$ {sudo -H} npm i -g npm
$ npm i --save lodash.clone
In Node.js:
var clone = require('lodash.clone');
See the documentation or package source for more details.
