IMHO yes, a lot got better.
The first thing that comes to mind are tools like create-react-app and angular-cli. No more manual webpack-configuration. It's very easy to get started.
Another one is that native JS-modules are widely supported. No need to worry about bundling or transpiling until much later in a project (unless you need TypeScript or JSX of course).
How do those affect end users and improve their experiences with front ends for the better?
They don't. They improve developers' lives.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
