I’ve worked at several places that didn’t have formatters when I started. they did by the time I left. you can incrementally adopt them and if it’s automated most people at worst don’t care. advocate for things you want

reassignment and hoisting are the significant ones. behavior around this does just seem more intuitive than otherwise when it comes up, so I think telling especially new devs to use const arrow fn everywhere but classes is a reasonable rule

hate to break it to you but it behaves like a variable either way. function just behaves closer to a var variable. const fns are less like variables since no assignment. intellisense/devtools all show them just fine. it really is just a minor aesthetic difference on the definition
