After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

well....can someone teaches me that is Object.assion() appropriate here , I think its dangerous because it remains connection to origin collection array ,which can change the former array sliencely :(
hhhhhhhh amazing solution
well , we can use Array.from() to convert arraylike object to a truely array, however this task seems to apply many languages ,which means in Js maybe the form of inputs are just truely array
it is so beautiful and I am superised that my code is similar to this solusion ,I'm just a noob guy here XD
