Share your thoughts on the RxJS learning curve.

I'm learning RxJS and I'm overwhelmed by the number of operators.

So I joined a company as an Angular dev and the code they gave me was stupid AngularJS ported to Angular 7 mixed with thousands of lines of jQuery inside index.html,

also all the css was scattered into a few files with 8000+ lines of code and no idea about which file does what, we decided to rebuild the project in Angular,

I built a huge portion of it with PrimeNg (a UI library like Angular Material) but after building all of that they tell me to remove PrimeNg and also asked me to import all SCSS modules in angular.json like wtf,

they forced me to use bootstrap with jQuery IN AN ANGULAR PROJECT this was my first job and I think I have a pretty good understand of Pakistani IT industry after this.

I learned programming from online paid courses and tons of practice so I expected others to be on the same level but that's not the case.

Who agrees and which editor do you use ?
