Then you should come to the forum and ask.
We can help you learn how to break down tasks into doable chunks.
Learning how to ask questions is an important skill that is required on the job.
So it is important to learn how to do that now.
I suggest you practice building projects through something like frontend mentor.
They give you a basic design and your job is to implement that design and build out the functionality yourself.
So they don’t tell you how to solve the problem.
They just tell you what the basic functionality is supposed to be. Then it is up to you to figure out how to build it.
That is the type of practice you need right now.
Pick a project that has some JS.
Something like this one
Read through the brief and look at the design.
Start with the basic HTML elements you can identify on the page.
Then focus on the functionality portion.
One of your first questions should be “How do I calculate someone’s age from their birthday”
Figure that out first.
Use console.logs to test your code to see if your function for calculating age works.
If you need help, google “how to get someone’s age from birth day javascript”
there are tons of answers, articles, videos to help you.
Then you figure out how to display it on the page.
Then you figure out the other functionality mentioned in the brief.
Then you start figuring out how to style it so it matches the design they gave you.
That is how you break a problem down
You first need to understand what is being asked of you.
Then you take one piece at a time.
As mentioned earlier, if you don’t know how to break it down, ask the forum for help.
The more projects you build, the more you will learn how to develop your problem solve and debugging skills.
hope that helps
