Is it just me does anyone else feel that javascript world has gone crazy?

Hello everyone,, To begin with, there are so many js frameworks out there that's enough to intimidate a newbie who wants to learn "just javascript". Things in js world change so fast that we can barely keep up. I'm so thankful that I got a job as a python developer. But, when i was searching for jobs, I spent time learning reactjs. Then, I realized not everything can be done through react easily. So, I transitioned to angularjs. I had to learn nodejs and typescript too. This was back in 2017. Now, I look back through my udemy courses and a major portion of reactjs have got updated and there's again a learning curve. Why is this ? Or is it me who's making a big deal out of this. If so, how do javascript developer keep up with things changing so fast?
