I'd not call python stable, a language where new major releases are breaking compatibility with previously written programs for that language, for me personally, is offending beyond the point of polite conversation.

Now, js and its ecosystem are two different beasts.. The language itself is fairly hipster, but the frameworks and some of the people writing them are even more so, they like to move fast and break things, and to be honest, there should be corporal punishment for every dependency you pull via yarn or npm, and additional (if lesser punishments) for each dependency they pull.

Drop as much out of that ratrace you can and concentrate on writing your software.
