Googling for javascript clone object brings some really weird results, some of them are hopelessly outdated and some are just too complex, isn't it as easy as just:

let clone = {...original};

Is there anything wrong with this?

This is good for shallow cloning. The object spread is a standard part of ECMAScript 2018.

For deep cloning you'll need a different solution.

const clone = {...original} to shallow clone

const newobj = {...original, prop: newOne} to immutably add another prop to the original and store as a new object.
