It's pronounced Diane. I do data architecture, operations, and backend development. In my spare time I maintain Massive.js, a data mapper for Node.js and PostgreSQL.
The reduce accumulator doesn't have to be one value -- it's quite useful in places you'd use both filter and map to choose some elements of an array and generate derived values, and you only have to traverse the array once.

But for sub 100 items, the lose in clarity isn't much worth it.
