How to get the HTTP protocol version via JavaScript

Is it possible to determine the HTTP protocol version using JavaScript? I need to detect if the user is using HTTP/2 protocol (and congratulate him if this was the case).

Works in

  • Edge since 17
  • Firefox (Desktop and Mobile) since 45
  • Chrome (Desktop and Mobile) since 61
  • Safari Mac 14.1 (tested here, but not yet updated on MDN/caniuse)
