Am I the only one that feels like they're cheating when they use libraries like Angular to make stuff easier? I dont want to feel like that but it just seems to happen :/

If your project has more code done by yourself, then you just haven't googled enough to find that somebody else did it already, heck there's even a library in npm for string padding that is used in thousands of projects.

Depends on what your goal is. If you want to make a good, performant and small product, use libraries moderately. That means using them if they provide something you can't just do yourself in no time, and if they are optimized and supported well.

If you're aiming for development speed for a small personal product for instance, use libraries. No need to suffer.

If you are trying to learn, use often used and complex libraries, it's more likely that you will need those later, than that you will have to know how to replace them. But avoid those that only do small things and those you will never use again.

@david-hil I haven't used any of them yet because I'm waiting until I'm better with vanilla JS but I feel like when i do start using libraries like angular i feel like I'm cheating or something.

I get like that when there's easier ways to do things, so the "Oh id only use that because Im too stupid to figure out another way or understand the original way" thought shoves through my head and makes me feel like a horrid programmer
