How does lodash.clone work?
lodash.clone
creates a shallow clone of a given object or array. This means that it creates a new object or array, and copies over the properties or elements from the original object or array. However, if the properties or elements themselves are objects or arrays, they are not cloned - they are only referenced by the new object or array.
For example, if the original object has a property that is an array, the cloned object will reference the same array as the original object. Therefore, if you modify the array in the cloned object, the original object will also be modified.
lodash.clone
takes one argument, which can be an object or array. The function returns a new object or array that is a shallow clone of the original.
Note that lodash.clone
only performs a shallow clone. If you need to perform a deep clone, where all properties and elements are also cloned recursively, you can use lodash.cloneDeep
.

const _ = require("lodash"); const original = { name: "John", age: 30, pets: ["dog", "cat"], address: { street: "123 Main St", city: "Anytown", state: "CA", }, }; const cloned = _.clone(original); console.log(cloned); // { name: 'John', age: 30, pets: [ 'dog', 'cat' ], address: { street: '123 Main St', city: 'Anytown', state: 'CA' } } console.log(cloned === original); // false console.log(cloned.address === original.address); // true
In this example, we have an object original that has some properties and an inner object. We use lodash.clone to create a new object cloned that is a shallow copy of original. We then log the cloned object to the console and verify that it is indeed a copy of the original. We also use the === operator to check if cloned and original are the same object (they are not, since lodash.clone creates a new object), and check if the address property of both objects refers to the same object (it does, since it was not cloned).
