Master of none

I have about 5 YOE. 2 in QA and 3 as a full stack web + mobile developer. I've been switching libraries, frameworks and languages a lot. This has resulted me in becoming mediocre in everything. Especially when it comes to languages, I forget the nuances of each one, the syntax. Because I struggle personally memorizing or remembering how to do certain things, I struggle unless I refer to documentation. Now, this isn't a big deal when working in a job or personal projects. Because you can just Google what you don't know. But this weakness is pouring into my struggle with tech interviews. I'm mixing up syntax with a bunch of languages. In a recent interview, I had to sort an array. I had to initially do it in Python, because that's a language the job requires, but I forgot if I should be using sort or sorted. Then I thought I could maybe do it in Typescript, but I totally forgot that you need to pass a callback to sort it. It's these basic things which I'm struggling to remember. I'll be honest, I'm a little stubborn when it comes to memorizing stuff, I hate it. My mind automatically goes "why memorize this shit". Anyways, I was wondering if anyone has dealt with this before and if they "fixed" the issue, how did they do it.
