How to learn the material correctly?

Question

IT education

Please tell me how best to assimilate the material, that is - if, for example, I didn’t understand some aspect, then is it worth running into it or is it better to figure it out later, and is it possible sometimes to skip some aspects (I don’t know how to say this), or you need to delve into right into each punctuation mark (it just happens that I get a little distracted and skip a couple of lines) or it’s easy enough to understand and it doesn’t matter what I missed.
UPD: And how much time to spend on practice, and it also happens that I sometimes get confused in some operators and get a little stupid, will it pass and how long will it take, and how to speed up this understanding?

Answer 1

1. Read the new material in such a way that most things are understood while reading.
2. Outline in a text file or github or somewhere else. In your own words, for yourself. Even if the Internet already has all sorts of MDNs that open at the click of a finger.
3. Practice. I learned what CSS grids are, go make some examples of element layouts, save them (in a file, on codepen, on github, as you like). You can comment on the code, chewing it to yourself from the future. This is a cheat sheet example, when you return to it, you can quickly remember everything.
4. Repeat steps 1-3 in a week, a month. You will already read through your fingers, because you know the material and just remember, you can use the summary or supplement it. Concrete examples and summaries of specific technologies are very helpful and will help later as cheat sheets. Especially if you made them yourself.

Answer 2

I take a textbook, read it completely, experimenting with examples from the book along the way. After reading, I'm trying to bomb a pet project using the technologies I've learned. If I get stuck somewhere, I re-read the relevant chapters, I climb into the official documentation, I google.
Comes with practice. After how much - it depends on your individual learning abilities and the intensity of the applied efforts.

Answer 3

Spend 80% of your time practicing. You need to memorize only in practice, applying these skills. Just learning theory is a waste of time.
