I'm a Python guy, but there are lots of things about JS that make me jealous. For example, the main implementations are quite fast, and the tooling is good. In Python, there is Pypy which doesn't get enough investment, or CPython where your only optimization lever is "rewrite it in C!". TypeScript also seems quite a lot nicer/less-broken than Python's mypy. Lastly, I like that JS has actual, multi-expression lambdas and a pleasant syntax. Some things are more pleasant in Python--everything is sync by default, there's less churn, the standard library gets me a lot farther, it's less permissive (no 'undefined is not a function' nor '!= vs !=='), etc. Both languages serve similar niches well, but the feeling I get is that JS is quite a bit faster and nicer for IO-heavy workloads (JS just has a more mature async story than Python) while Python is generally more intuitive and perhaps better for general application development. But for most things, one isn't dramatically better than the other, and they're both a good deal more disappointing than Go. :p
