Feature request

Is your feature request related to a problem? Please describe.

It would be nice to have a built-in helper to detect if code is run on server or on client.

Describe the solution you’d like

function onServer() {
    return typeof window === 'undefined'
}

if(typeof window === 'undefined') {
  // some code
}

Turns into this on the client-side code:

if(false) {
  // some code
}

And is tree shaken away so ends up being removed from the client-side bundle.

Increasing the api surface would make these optimizations significantly harder and non-standard.
