How to Deep clone in javascript

Question

How do you deep clone a JavaScript object?

I know there are various functions based on frameworks like JSON.parse(JSON.stringify(o)) and $.extend(t

Answer 1

Lo-Dash, now a superset of Underscore.js, has a couple of deep clone functions:

• _.cloneDeep(object)

• _.cloneDeepWith(object, (val) => {if(_.isElement(val)) return val.cloneNode(true)})

  the second parameter is a function that is invoked to produce the cloned value.

From an answer of the author himself:

lodash underscore build is provided to ensure compatibility with the latest stable version of Underscore.
