Answer 1

All resource hints can be used only as attributes on a <link> element. You can read about what they do and how for example here

So there is nothing you can do directly in JavaScript (except of course adding the attribute to existing link dynamically based on user action)

If your are requesting something using Axios from domain https://api.my-app.com, just including <link rel="preconnect" href="https://api.my-app.com" /> into your page should be enough...
