1. JavaScript has "bad parts", yes, but we can just ignore them. Allow me to use an analogy here: Image you have a smartphone that has 100 apps installed, and of those 100 apps, 10 are crapware (e.g. pre-installed vendor-specific apps that are just bad). Does this make the phone horrible? No, of course not. Just ignore that crapware. Even if you can't uninstall it, it's not an issue for you. Use the good apps, install more good apps if you like to (analogy to JavaScript libraries) and ignore the crapware (JavaScript "bad parts"). 2. That's literally what web components are for. Read OP's post. We will have <calendar-widget> and <login-form> and many more custom elements with plug-and-play functionality.
