You have a couple of small mistakes

var answer = prompt("what is the best programming language?");
//Put your string in quotes. Use parenthesis with your method
//if (answer.toUpperCase === JAVASCRIPT) {
if (answer.toUpperCase() === "JAVASCRIPT") {
  //add semicolon
  //document.write("You are correct")
  document.write("You are correct");
}
