Being able to develop with instant feedback and without any tooling is pure joy. Just open a simple text editor and within minutes you have something up and running on your own computer without having to install anything. Then when you want to publish it you just upload it as is to a web server. And if you need to write a server all you need is a single program called NodeJS where you also get instant feedback and it comes with a standard library that lets you do just about anything. The only negative about vanilla JS is that writing async code is difficult, but no tooling can solve that problem. Try vanilla JS for one year and your productivity will go up one or two orders of magnitude, because development is now fun, fast and simple. Just don't write too big of a project because when you start to bring in tools its a slippery slope. And don't write your own tooling because its very addicting.
