Python hit its stride a long time ago. The Javascript ecosystem has only quite recently reached sufficient performance, usability and adoption to be a serious general purpose language and it's red hot as a job skill. Python is not dead, but it's not exactly blowing up at this point.
Depends on what domain you work in. If I used nodejs or web services, then I would be enamored of Javascript. But I do an data analysis and ETL, a domain that Python and friends excel at, I not concerned as what's "hot" and "in" at the coffeshop.
