JavaScript used to be easy to get into (and I suppose technically still is) but the old days of open a console and type in some code or put a src file at the top of the HTML page seem to be gone for most practical and production purposes. Now it's typescript and webpack and a 200 hour course to get started with React. And big teams tripping over each other making components.
The funny thing is, I don't know that the resulting product is really much better.
