Can you reach the throne?

You (brian) are allowed to change the cleaning code, but nothing else.

JS Fiddle here

castle.js

function foo() {
  // Let the boy clean the castle
  document.write("Cleaning")
  // WRITE CLEANING CODE HERE
  
  // END CLEANING CODE
  document.write("<br/>")

	// NOT ALLOWED TO CHANGE FROM HERE
  const castle = (
    name,
    throneProof = undefined
  ) => {
    document.write("Hello,", name, '<br/>')
    if (throneProof != null) {
      document.write("<strong>WELCOME TO THE THRONE!</strong><br/>")
    } else {
      document.write("<em>Keep cleanin', sucker!</em><br/>")
    }
  }

  function guard(name) {
    if (name === 'King') {
      castle(name, true)
    } else {
      castle(name)
    }
