I came here to say this. Transcrypt takes the approach that there are already many good JavaScript libraries that exist for web development, and rather than try and replace those, it embraces them. What it allows you to do though is to write code that uses those libraries in Python, and then transpile that into JS for deployment. It has allowed me to write React + MaterialUI apps using 99% Python, without taking a performance hit in the browser.
