How to clone a javascript ES6 class instance

Question

How do I clone a Javascript class instance using ES6.

I\'m not interested in solutions based on jquery or $extend.

I\'ve seen quite old discussions of object

Answer 1

Another one liner:

Most of the time...(works for Date, RegExp, Map, String, Number, Array), btw, cloning string, number is a bit funny.

let clone = new obj.constructor(...[obj].flat())

for those class without copy constructor:

let clone = Object.assign(new obj.constructor(...[obj].flat()), obj)
