Question

IT education

Yesterday I asked a question, but it disappeared) I did not have time to read the answers, but the thought appeared: Try each of these three languages ​​up to "Core-level" within 3-12 weeks (final). So, if you start from the very beginning, where can you "draw" a line in them, on which you can roughly look at the development directions (in Java, for example, learning Java itself until you can, for example, start learning for the Web Spring)?
At the same time with all this, I’ll see how these 3 (or one of them) will call me and, based on this, make a choice and start pulling up the Frontend (if I want to use the Web)
