I said ESLint. Not Javascript. ESLint is a linter for JavaScript. That's why I put JavaScript in brackets. Some people don't know what ESLint is. I'm talking about ESLint the whole time. Its not JavaScript specific but it's mostly used for JavaScript
You yourself are talking about ESLint. You said that ESLint won't prevent me from creating unused variables and functions when it clearly does. It won't even run and throw an error
Edit: ohh it's a Lemmy bug. The comment didn't update yet. Originally I said "ES6" then I changed it to "JavaScript" and then I changed it to "ESLint (JavaScript)"
What the post is about is compiler based clean code enforcement. JS doesn't do this, but your editor in combination with ESLint prevents you from running the program. However this isn't a general JS thing, just the way your setup works.
Just saw your edit, and yeah, that makes sense as to the confusion.
Either way, your comment enquired as to whether it was "the same" and it still isn't because for Go it's a language feature and ESLint is not a language, it just allows you to create similar behaviour for JavaSvript which, by default, does not exhibit that behaviour.
