I freaking love Jetbrains/IntelliJ. I have been a professional dev for 10+ years (18 years as a hobbyist) recently working with TypeScript, Laravel, Go and Rust. If you're working with Java it's basically a no-brainer. I have used fully-loaded (neo)vim with LSPs and plugins, Doom Emacs, VS Code since first release, and a bunch of editors and IDEs in the past. IntelliJ is in a league of its own 👏 Refactoring, Git integration, code structure to navigate large codebases quickly, debuggers, Docker/K8s services, database editor, diagrams, package vulnerability checkers, web inspector for writing tests, and now the AI Assistant! Amazing - I basically live in IntelliJ.

so many features, you couldn't possibly know them all but i love that they're there.

My IntelliJ subscription is some of the best money I spend every year.

IntelliJ Ultimate is a piece of art, I did not even know the language injection feature existed, now more time saved for me :D.

IntelliJ IDEA: You spam tab and the program writes itself to absolute perfection.
11/10 IDE.

How about creating a what changed video when you release a new version eg 2023.2 was released today and an accompanying video would be nice.

Love IntelliJ! This makes it hard to swallow that Copilot Chat is now only available on VSCode... Will it land in IntelliJ any time soon?

getting more and more hanging, glitching since last year :|

[walterclementsjr.]

I'd happily let intellij take 3GB of RAM any day.

[olsexki]

So fast your presentation. I can't follow with you.

Exactly same content repeated over and over again by different folks. Nothing new here, i just feel JB is loosing the game now.
