If you try simple vanilla javascript, then you may be surprised at how pythonic it is in cerain ways - e.g. just open a browser (any browser!) and you have a javascript REPL read to go in the developer tools.
Node severely complicates and confuses things, but node alone is not javascript. Vanilla JS is IMHO a very nice and expressive language, and you do not need any of the Node/Webpack/React/Vue/jquery/whatever to do effective things in Javascript these days as it is very capable on its own.
