javascript-lodashHow do I use Lodash's cloneDeep() method in JavaScript?


Lodash's cloneDeep() method is a powerful utility that can be used to create a deep clone of a given object. This can be useful when working with objects that contain nested properties.

Example code

const _ = require('lodash');

const originalObject = {
  name: 'John',
  age: 30,
  address: {
    city: 'London',
    country: 'UK'
  }
}

const clonedObject = _.cloneDeep(originalObject);

console.log(clonedObject);

Output example

{
  name: 'John',
  age: 30,
  address: { city: 'London', country: 'UK' }
}

The code above will create a deep clone of the original object, meaning that the new object (clonedObject) will contain the same properties and values as the original object (originalObject).

The cloneDeep() method can also be used to clone arrays, functions, and other complex data types.

Code explanation

  • require('lodash') - imports the lodash library
  • _.cloneDeep(originalObject) - creates a deep clone of the original object
  • console.log(clonedObject) - prints the cloned object to the console
