If you're actually interested in learning, there's a pretty good series "Emacs From Scratch" on the systemcrafters youtube channel. He starts with a completely empty emacs config and builds it up to a full blown IDE explaining how everything works along the way. Some of the things he does, there are better alternatives these days but most is still relevant and it'll teach a lot about how emacs works. That said, emacs is more of a hobby than an IDE. If you just want to get work done, using something like vscode or intellij or whatever else makes way more sense. If you find it fun to tinker around and customize your editor you can make emacs incredible, but it's something you have to want to spend time on.
