Yep, I rewrote my OSS Dropbox like frontend for every file transfer protocol in vanilla JS [1], so far it's not only faster with smaller memory footprint, the app is faster to boot, lighter in size despite the optional build system, there is no framework code I don't know about running at the worst possible time and I can effectively run to the maximum of what a browser can do.

It's refreshing to be able to open the network tab and see the original files coming out [2] and the developer console showing the full structure of it untouched in the same way it's visible from github.

This has opened new doors that was previously closed with any kind of framework, the option to dynamically patch those js file at runtime to customise the interface for unique needs that make sense for someone but wouldn't make sense for 99% of everyone else. Now it's just a matter of submitting a small plugin patch that do it and tada, a happy customer while maintaining only a single codebase
