The article makes out like auto completion and help on hover are new things, but RStudio IDE has had them for years and years.
R/RStudio was my first language/IDE. I was horribly shocked when moving into other languages to discover they didn't have things you got out of the box with R/RStudio. "You mean I have to look up documentation for a function/method!?! - that's supposed to be automatic!".
R has a bunch of features which other languages lack to the degree that it's a rude shock to learn that other ecosystems lack them. One is the REPL with extremely convenient RStudio keyboard shortcuts to run lines of code (to achieve similar with ruby, I have an elaborate neovim/slime setup that took hours to configure and still isn't as good as RStudio gives out of the box).
A sign of a brilliant tool is when an idiot can get more done with it than an expert can with alternatives.
