“Lightweight”, “Python” and “Minimal” are the key factors why developers consider Flask; whereas “Can be used on frontend/backend”, “It’s everywhere” and “Lots of great frameworks” are the primary reasons why JavaScript is favored .

Thanks to Flask, a backend this compact and controlled is capable of handling all the data processing required to support a full-featured frontend finance tracking app for fiscal fanatics, like me! I hope you’ve enjoyed my article on Flask as a compact backend development tool for Python.

Everything else runs on a server somewhere, not in the browser, and that makes it “back end”. Flask, which is written in Python, is back end .
