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.
Ohhhh, thanks, nice explanation
If you pass 0 to the function, it will return -0 yes, but when you try to display -0 (for example, with console.log(-0)), it will appear as 0. This is because JavaScript generally doesn't distinguish between 0 and -0 in the output.
negative 0? ahahahha nice solution. How it's passed test? Mistake or miracle?
