I moved back to Mocha with Chai for a while (both have great ESM support, quietly still well maintained, despite predating Jest) and then to Node's built-in test harness (and Deno's), sometimes still using Chai rather than `node:assert/strict` or `jsr:@std/assert`.
But I wasn't using a lot of Jest features anyway, generally preferred Mocha even during the height of Jest's popularity, and Node's test runner is sufficient for most of my needs (and Deno's starts to seem more and more the path forward as I come to prefer deno.json in a lot more types of projects than package.json).
