alt Hacker News> you would eliminate all usage of innerHTML
The mythical refactor where all deprecated code is replaced with modern code. I'm not sure it has ever happened.
I don't have an alternative of course, adding new methods while keeping the old ones is the only way to edit an append-only standard like the web.

I kinda like the way JS evolved into a modern language, where essentially ~everyone uses a linter that e.g. prevents the use of `var`. Sure, it's technically still in the language, but it's almost never used anymore.
(Assuming transpilers have stopped outputting it, which I'm not confident about.)
It for sure happens for drop in replacements.
Nobody's talking about old code here.
Having an alternative to innerHTML means you can ban it from new code through linting.
If you want to adopt this in your project, you can add a linter that explicitly bans innerHTML (and then go fix the issues it finds). Obviously Mozilla cannot magically fix the code of every website on the web but the tools exist for _your_ website.
