  Yeah, it's a slight exaggeration to say that `var` is effectively not in the language anymore, e.g. I see it plenty when reading open source projects or Babel output. Keep in mind that ESLint can autofix `var` to `let` or `const` (except in some rare cases when it's unsafe), so even if you have a big legacy codebase, it's not hard to migrate completely away from `var` with very little time or risk. But it's true that you need to keep up with tooling for legacy projects, which happens to be the case for the stuff I work on, but may not be universally true.
