Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. 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.

the bracket takes time lol
methods were utiliezed:
forEach、typeof、includes、?:
Because that requires Node v20: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/toSpliced#browser_compatibility
I have tried to solve that issue by using 'toSpliced method' which allows to create an copy instead of only 'splice method' (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/toSpliced).
But the compiler keeps telling me it isn't a function(??).
"==" is interesting test
until now i recorgnize the benefit of arrow function's magic

map? creat a new array ,it sounds much more logical than slice method,and map method could smoothly do a loop
what a crazy code lol. Just utilize slice method to create a totally new array.🤔😴😴🤩
