I'm not understanding why some babel packages appear within my node_modules, while others do not. I have
"@babel/plugin-proposal-optional-chaining": "^7.16.5",
in my babel.config.js in the root of the project tree. I did
npm i --save @babel/plugin-proposal-optional-chaining
but the plugin does not appear in my tree afterwards. It does appear in package.json under dev-dependencies, and I added it under dependencies too, followed by npm install.
Any idea why this package seems to install correctly but does not appear in my tree ?
