My advice as an internet nobody:
Don't worry about that dumb crap. JS is a good language. It's come a long way since its dark early days.
People who shit on JS and on those that like it are usually not worth your time. I find those people are more interested in displaying their intellect or superiority by being condescending. It's not helpful.
Read and watch Douglas Crockford if you haven't. He has extracted the best aspects of Javascript to focus on. If you take his advice then I believe you will find JS to be a very good companion.
Just don't let JS be your only language. No language should be your only language.
