JavaScript not considered harmful

Each topic that was brought up in the Slack channel has a heading with a answers between them.

JS in html file as <script/> vs having a separate JS file (generally best practices)

So this is a question of trade-offs. Sometimes you need to have some JS inline with your HTML due to your web framework. Eg. You have some JS that sends Google Analytics/Mixpanel events and needs to have a user's email address which must be given to your JavaScript.
