#javascript is such an interesting language in that the more you use it, the less you feel like you know 'how' to use it. Part of this is you start reading about how others use it and feel like your way is not the "right" way. Instead, just realize that it's so popular and flexible that you can use it any way you want and you'll still get to some kind of working solution. This is a strength.
Of course when you start working with other folks you need to agree on coding standards and best practices, but that's nothing unique to JavaScript.
So, if someone laughs at you for still using jQuery or something, just chuckle along and keep doing what you want. You could spend a lifetime seeking the perfect library for JS and still not get anything done.
Instead, keep a attitude of learning every day, and question your own preconceptions.
Not to long ago I learned about #functional programming. I'm still exploring the ramifications of that. But, JavaScript is still here to help me make stuff.
