As always, you gotta know both so that you can pick the right tool for the job.

4 years isn’t enough to hate javascript. Either those 4 years are entirely in JS, in which case it’s all you know and thus you lack perspective. OR, you spent e.g. 2 years with a different language and only 2 in JS, in which case you don’t have enough experience with JS to have an informed opinion.

Don’t worry though, we all started our JS hating journey like that. Give it a few more years and I promise you’ll be able to hate javascript like the masters.

I kinda feel like people who shit on it have never used it much, or aren’t very experienced

How much experience do you have? (and don’t even think about lying; this is the internet)
