Eve programs aren’t talking to a database, they are the database. That means no plumbing, no impedance mismatch, and no extra infrastructure is needed.
Everything is data. The file system, http requests, the DOM… That means everything can be queried and everything can be reacted to.
Eve’s semantics were built for concurrency, asynchrony, and distribution. There are no promises, or thread synchronizations, or borrows.
Eve programs practice literate programming, since there’s no incidental ordering imposed by the language.
Another result of a lack of ordering is that programs grow very organically through composition.
Eve programs are naturally tiny.
Correctness can be defined globally through integrity constraints, allowing people to safely contribute to an application without worrying about checking every possible invariant locally.
