To be fair, Node has `node:test` [0] and `node:assert/strict` [1] modules out of the box for several LTS versions now. `node --test` can easily replace Mocha and `node:assert/strict` is fine, but `chai` is still sometimes nicer (include ergonomics like `expect`). (Deno's @std includes an `expect` style assertion library.)

Of course, the trouble is that there are so many test runners in the Node ecosystem and many of them cannot be as easily replaced as Mocha, so the shift to the out-of-the-box test harness and assertion library will of course be painfully slow. People like the over-complicated nature of both Jest and Vitest for all sorts of reasons. Major companies thought Karma was a good idea. (I still don't understand why more developers didn't cringe at "Yo dog, I heard you like V8 for your unit tests, so we're gonna spin up a second, different copy of V8 from your existing V8 environment.")

Much came after Deno added them. I don't know what will happen to Deno, but I am glad they showed the Node world than life can be a little more pleasant
