Spotted a non front end developer.
I'm being honest here -- there are things you need to learn. You may not like them at a beginner or someone new to the stack, but they are here as industry standards for good reasons (which I won't go into here).
By the way, JavaScript is not necessary a language as "easy" as you think is. I have seen plenty of bad code written by professional software engineers. Seriously, you need to put a lot of effort into becoming a good front end developer.
