I have to admit that I really love web components ever since Polymer 1, and agree with the article sentiment (this post was starting to get to be a mirror of many of the authors thoughts, so cut it down)

It is very interesting watching the Web cycles, and found it curious how many people here were sad that typescript was not mentioned. There are some fun (though I suppose dangerous) things you can do without it, and I've found it has had very many instances not helped me where expected like a fully matured typed language has. And I've worked with a lot of people who just went I added types and don't know how to use generics.

I guess if you have it poorly implemented, then it's best to leave as JavaScript. And, web components you can keep things very simple... Which helps keep many errors down.
