Week 1 Exercise 2.6 While and Optional Break

This was my answer. I did not take into account the else if statements.

var answer = prompt ("What is the value of 2+2?");
while (answer != "4"){
  var answer = prompt ("No, try again. What is the value of 2 + 2?");
  if (answer == "4")
    break;
      }

The solution provided by the book was more elegant. It used the while statement that if true, will continue to run until the break.

var answer;
while (true) {
  answer = prompt("You! What is the value of 2 + 2?", "");
  if (answer == "4") {
    alert("You must be a genius or something.");
    break;
  }
  else if (answer == "3" || answer == "5") {
    alert("Almost!");
  }
  else {
    alert("You're an embarrassment.");
  }
}
