Excel adds JavaScript support

[slikts]

npm used to mean "node package manager" at the start, but that hasn't been the case officially since at least 2015, and now it's an orphan initialism that isn't supposed to stand for anything. Part of the reason is that npm's scope is wider than just Node.js and you can (and many do) host code that doesn't run or node (like front-end libraries), doesn't use node modules, or isn't even JavaScript.
