Sneaky trick you might find entertaining? A LOT of these object and element methods return the object/element you target. Thus, well... get a load of this.

Object.assign(
  document.body.appendChild(
    document.createElement("button")
  ), {
    name : "delete",
    value : '102' // record number
  }
).textContent = "delete";

Crazy stuff. And why I prefer appendChild to append.
