I got my first programming job in 1996. I still have days like this.

Today, I had a conversation with my boss about an apprentice in our team. Our senior front-end dev left a few months ago, and the apprentice has had to take on a lot of work with little guidance. Our team is very full of back-end devs with no front-end experience. During this conversation, we described our apprentice as “extremely capable but lacking experience”, and discussed the best way of getting him more experience. The conclusion we came to is that there is no shortcut here, but having good guidance from senior devs can help somewhat.

What I’m trying say here is that what you’re describing is absolutely normal, and based on what you’ve said, you’re doing fine. You have a little imposter syndrome, which seems worse than it is because of your genuine lack of experience… that experience will come with time, and days like today are the days where you learn a load from your mistakes. You’ll probably not hard-code things like that in future, and today you gained a tiny bit of that experience that you need - well done!

Just two months in and it's your first time in the job? You're good my man, your doing exactly as expected.

maybe we could do it this way or that way

This is where a team coding standard, naming standard, and formatting standard really helps.

You're always going to receive feedback on your code. Part of what makes coding fun is that there are a million different ways to make something that works and most people are going to think their way works best. More experienced engineers most likely do know a better way to do it, so take their suggestions, figure out why it's better, and apply those principles to all of your code. But sometimes junior level people come up with great ideas. It's important that you know why you made certain decisions, and to be able to defend those decisions. After considering recommendations, consider if they are actually better, and if you think they aren't, then have a conversation about that.

If you don't have experience working with dynamic data then it's normal that you just forgot that you needed props instead of text (or whatever your situation was). Now that you made that mistake, you'll probably never make it again.

Don't be too hard on yourself. There is too much for any single person to remember. I've been doing this for 20 years and I still have my head in the docs several times a day. On that note, make frequent and liberal use of the documentation. It's okay to forget stuff you haven't done in awhile. Yesterday I forgot what the freaking span element was called and I've made spans a hundred million times before. It just poofed out of my memory. What's not okay is not knowing how to find the information you have forgotten. Again, learn the docs and use them religiously.

Always remember that there are two states to every programmer. That link is a funny but accurate reminder of something we all experience..

Good luck. We're all counting on you.

Just to add. It’s not that I was incapable of loading the data in a dynamic way, it’s more the thought process and it didn’t occur to me at the time.
