@val @scope("document") @return(nullable)
external getElementById: string => option<Dom.element> = "getElementById"

let root = switch getElementById("root") {
| Some(el) => el
| None => Exn.raiseError("Root element not found")
}

let hello: unit => Dom.element = () => {
  Van.Tag.make("div")
  ->Van.Tags.addChild(Text("Hello, World!"))
  ->Van.Tags.build
