Unfortunately, it’s easy to feel overwhelmed and confused when you start learning JavaScript, or any programming language, for that matter. The world of software is massive, there’s just so many things to learn!
Some of them think: “I’ll never learn enough to be a good developer.” Probably you are thinking the same too I have bad and good news about it, but the good news outweigh the bad news, thankfully.
On the one hand, you’re right. There’s lots and lots of things to learn. I’ve started learning my first language (JavaScript) when I was 13, as a hobby. Now, I’m 31 and I’m still learning about the language. And I’m sure I’ll continue learning new things in the future.
On the other hand, you don’t need to know everything to be a good programmer. I became a professional dev at 18 years old. At that time, I knew far less about JavaScript and other languages than I know now, but that didn’t prevent me from get jobs and build amazing things in my career.
Think of programming languages as tools in your tool belt. The more tools you have, the more things you can do. But you already can do many things with the tools you already have.
And one of the keys to improve as a developer (and any skill) is just being persistent. If you keep learning and practising, you’ll become a better programmer over time.
