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.
Mostly there are more submit tests than example tests. There tests test more than the example tests.
Did you check for null before?
If the object is null, you cannot apply reduce for this.
Hope this helps!
why i got this error?
TypeError: Cannot read property 'reduce' of null
