The worst part about working in JavaScript is the insecurity. Everybody likes to act like they know what they are doing, but very few people really do. So, for most people its entirely a game to remain employed when they probably aren't qualified to be there in the first place. Its like musical chairs where everybody hopes when the music stops its the next guy left standing.

For the few people who do know what they are doing its an impossible situation. People simultaneously expect magic from you, because they know you can do it, but at the same bitch and cry about the output. They know they cannot write original code or extend somebody else's original solution so they demonize it out of self-preservation. When people are universally that insecure its convenient to hate on that one person who doesn't share that insecurity.

That is why I switched careers. I have never seen a salary high enough to justify going back to that.
