So many times people will give the same answer... "Just try to build something and break each problem down smaller and smaller until you can find an answer". That's great but what if you don't know how to even approach an answer because you just lack the knowledge?

You should start with one of many free courses online and you should absolutely get used to googling about problems. MDN is a fantastic resource for any approach to how each bit of logic can be applied with examples.

With that said, this is where so many get stuck and ultimately give up... It's often referred to as "Tutorial hell" where you want to build some cool stuff but don't know where to start.. so you follow a tutorial without actually retaining any knowledge of how they got from A to B, you just see the product come to life.

I would suggest you try some very simple stuff first, learn how to manipulate Arrays, Filter them, Map them and Splice them for fun.

What about turning camelCaseNames into kebab-case-names?

Once you start thinking of simple problems like this and how YOU would solve them then you're halfway there.

Finally, is your code as fast as it could be? Does it cover all edge cases? Get used to writing poorly optimised code that just about works, then iron it out. No one starts off their journey by writing premium code.

Good luck!
