Nodejs: how to clone an object

Question

If I clone an array, I use cloneArr = arr.slice()

I want to know how to clone an object in nodejs.

Answer 1

Objects and Arrays in JavaScript use call by reference, if you update copied value it might reflect on the original object. To prevent this you can deep clone the object, to prevent the reference to be passed, using lodash library cloneDeep method run command

npm install lodash

const ld = require('lodash')
const objectToCopy = {name: "john", age: 24}
const clonedObject = ld.cloneDeep(objectToCopy)
