Yeah, an automatic formatter and linter/language server handles the first 5 very smoothly. The 6th one (surrounding terms with word boundaries) is useful in many situations, but a lot of editors also support doing this natively; e.g. "Match Whole Word" in the VS Code search input fields. I don't want to be too cynical about the article, since these are absolutely all good things to know due to their myriad uses in other circumstances. But if your intention is to apply these to code you're writing, as the article describes, I don't think any of them are practical if you're already using an IDE/IDE-lite. (It probably makes a lot more sense if the author is using a lighter editor like vim without a lot of plugins, though.)
