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.

I got it now, although Englishwise doesn't make sense totally.

Accumulation can mean many things, not necessary addition. It's how the official documentation names the argument, and it is a customary name across platforms and languages for the argument of reduction operation which keeps, well, theaccumulated value.
Wow, great!
Although your code syntax is fine, but I don't believe accumulator is good name for the first parameter of reduce function as it doesn't add up, it multiplies.
