Great video. But what about structuredClone method?
@MonsterlessonsAcademy
@MonsterlessonsAcademy 2 года назад
You can certainly use it if you don't need to support older browsers.

great work but maybe it does not work with Date properties))) you should to add "... || input instanceof Date" to the condition of the first if statements.

So little views and comments for such a cool channel and useful information. Maybe collaborate with Brad Traversy or Kyle Cook?) Thank you for vids!

I would love to collaborate with them but they both didn't answer my emails.

@@MonsterlessonsAcademy That's strange, Brad promoted Kyle. Why wouldn't they support more good content... Try twitter, devs seem to be more active there, but u probably know it already

Before this usefull tutorial, I`ve known only variants how to implement deep clone array. How to clone function as property in an object ?
@MonsterlessonsAcademy
@MonsterlessonsAcademy Год назад
For example spread operator can copy functions. But the most correct answer is that you should not have functions inside your object because objects are representation of the data. Also it is easier to support plain objects without prototypes, functions, etc

how about structuredClone()
@MonsterlessonsAcademy
@MonsterlessonsAcademy 2 года назад
Sure you can use that if you don't need to support older browsers like IE for example

what about circular deps? let newA = { a: 1, b: [1, 2], c: [1, [2, 3]], d: { d1: 1, d2: [1, 2], d3: {} } }; newA.d.d3 = newA.d; let deep = deepClone(newA) stackoverflow!!

Hi you are totally right it will break as we don't check circular deps. But I don't think that having such things in a real project is a good idea and is needed (can't imagine such case).
