@clarfonthey That's a bit of a difficult one because there's not really one "JS ecosystem", it's more like two separate groups of people that drive change in the broader ecosystem; the startup bros (primarily responsible for the hype cycle) and the radical folks (primarily responsible for the 'invisible' infrastructure).

The latter group actually has a very good track record, and IMO a much better one than the language spec team! They've collectively standardized things like Promises/A+, CommonJS, ndarrays, lots of other semi-core things that are in widespread use. The former group is where almost all of the misery and framework churn comes from.
