This is one where I don't see the advantages outweighing the disadvantages. Python is, IMO, a moderately better language than JavaScript, but you don't get the Python ecosystem, and you aren't running the same code you wrote, so you won't get nice stack traces or even useful error messages. You'll be writing JavaScript in Python, using JavaScript libraries, but all the references are written in JavaScript. It's a lot of mess just to avoid writing JavaScript, which contains a pretty decent language at this point.

If you have some business logic that you want to run on both the front-end (maybe for quick local validation) and the back-end (for definitive validation) then this is useful over possibly rewriting you Python into JavaScript.

The base syntax of python is already a big plus when compared to js. It's only about avoiding the ambiguity of js, it js in general. I remember making a small webapp in flask and ajax. Most of the code is on the server, it's as little js as possible, and it has no js dependencies.

  What do you think is better about Python’s syntax? I generally like modern JavaScript’s syntax. I always figured the appealing part about python is the very good standard library.

    List comprehension, the indent syntax that makes it very readable, the builtin functions, globally everything. The philosophy of python is well described here: https://www.python.org/dev/peps/pep-0020/ https://www.python.org/dev/peps/pep-0020/ I especially likes this one: > There should be one-- and preferably only one --obvious way to do it. It's true that the standard library is good, but generally I do more things with basic python than the base of other languages. And honestly I've never understood how js prototypes work. Python just feels better. The syntax is less cluttered. That's a huge point of python.

  Js has awesome map filter reduce tho. I used to wish js has list comprehensions but now I prefer map filter reduce.

  JS's closest equivalent to comprehensions. Not as nice in my book, but really not bad either. https://sebhastian.com/list-comprehension-javascript/ https://sebhastian.com/list-comprehension-javascript/
