That is not what the author said. They said the JS Ecosystem was delightful. He then goes on to describe that Ecosystem. For some people that ecosystem is indeed delightful. They love the sheer complexity it takes to deploy a JS application these days. There is certainly a lot of choice and power out there for it. I personally am the kind of person who tries to ship my stuff as a single statically linked binary that I can just drop in place so I look as WebAssembly as a way to participate in the browser ecosystem while avoiding the whole NPM/JS Tower of development tooling complexity. I don't begrudge others from wanting to play there though.
