lodash.clonedeep
Advanced tools
Package description
The lodash.clonedeep package is a module of the Lodash library that provides a deep cloning function. This function creates a deep copy of a value, meaning that it recursively clones every level of nested objects or arrays, ensuring that no references to the original objects are kept in the clone. This is particularly useful when you need to manipulate data without altering the original source.
Deep cloning objects
This feature allows you to create a deep copy of an object, including all nested objects, without any shared references.
{"const _ = require('lodash.clonedeep');
const object = { a: 1, b: { c: 2 } };
const clonedObject = _.cloneDeep(object);
console.log(clonedObject); // { a: 1, b: { c: 2 } }
console.log(object === clonedObject); // false
console.log(object.b === clonedObject.b); // false"}Deep cloning arrays
This feature allows you to create a deep copy of an array, including all nested arrays, without any shared references.
{"const _ = require('lodash.clonedeep');
const array = [1, [2, [3, [4]]]];
const clonedArray = _.cloneDeep(array);
console.log(clonedArray); // [1, [2, [3, [4]]]]
console.log(array === clonedArray); // false
console.log(array[1] === clonedArray[1]); // false"}The 'clone' package offers deep cloning functionality similar to lodash.clonedeep. It supports cloning of complex objects like regexes, dates, and DOM nodes. However, it does not have the same performance optimizations and utility functions that lodash provides.
The 'deep-copy' package is another alternative that provides deep cloning capabilities. It is less popular and not as well-maintained as lodash.clonedeep, but it offers a straightforward deep cloning solution.
The 'rfdc' (Really Fast Deep Clone) package is a fast, simple deep cloning library. It claims to be faster than lodash.clonedeep for certain use cases, particularly when cloning plain objects and arrays. However, it may not handle complex or custom object types as well as lodash.clonedeep.
