Programming

In my experience it HEAVILY depends on the language you're using. Nothing beats Intellij for Java or Kotlin, but Rust and Go feel at home in any editor.

I know that LSPs and DAPs somewhat take care of these, but the following are often easier in IDEs:

• Refactorings, including really smart language specific ones
• Support for fancy frameworks. For example, Intellij can analyse all annotations for Dependency Injection or Spring stuff, and will then tell you exactly how everything connects on a higher "framework" level. Arguably, this is a solution to a problem Enterprise Java created
• Debugging is easier
• In general, stuff works "well enough" out of the box. As a fan of Neovim, I've definitely been frustrated a lot the first time I had to set something up
• Fancy integrations, for example linking frontend code calling backend code directly, or an entire little Database Manager builtin, with magic SQL code completion

Jetbrains IDEs do a lot of indexing and caching so that operations that normally take a bit are faster. Full text search, find usages, identifying interface usage in duck types, etc.

But the killer feature for me is the refactoring tools. Changing a function signature, extracting an interface, moving code to new files or packages, etc. I pair with folks who use VS Code and its a bit tedious watching them use find and replace for renaming things.

I've never been able to benefit from an IDE in a way that make up for how much slower and more bloated they are.

That does sound legit if you have resource limitations. Thankfully I've always worked for corporations that hand out MacBook Pros like candy. Normal day for me is having two Jetbrains IDEs open with Chrome, Slack, Zoom, and a dozen containers. Still runs smooth.

Niche language, but try out PureBasic.

Its IDE is based on Scintilla. And it is very fast, even on an ancient PC it runs. It is specific for the programming language.

And here some advantages it has compared to a simple text editor:

• Autocomplete of all functions and many API functions of the OS
• Hints about parameters
• F1 Help for all functions by just placing the cursor on them
• Jumping to errors in the code
• Automatic backups of all the progress of your codes, no problem to backtrace even if you forgot to save or commit.
• Manage Projects (Groups of source codes and different targets)
• Well integrated debugger

I agree with you in many points. Most other IDEs I am forced to work with are horribly slow. Especially those which rely on electron. Sometimes they lack features every basic editor has by now.

it really struggles with mid sized monorepo (think react libraries managed via NX)

Depends on how large your Python projects are. If you have a million lines of Python code, navigating quickly and directed is invaluable.

I used plain vim before for Python projects, but these never grew above 50k lines of code.
