for loop question for guessing game: even if i answer correctly, loop keeps running asking me me questions. How can i fix my code so it exit the loop after the 1st correct answer?

for (x= 0; x < 3; x++) { {var guess = prompt ("what is my name?")}
    if (guess.toLowerCase () === 'nick')
    document.write ("Good job guessing my name");
    else {
    alert('good try, better luck next time');
    }
};

I looks like you have a few misplaced curly braces and some missing around your if statement

for (var x = 0; x < 3; x++) {
  var guess = prompt('what is my name?')

  if (guess.toLowerCase() === 'nick'){
    document.write('Good job guessing my name');
  } else {
    alert('good try, better luck next time');
  }
};

Apart from the curly braces, you need a way to exit the loop after a correct guess. The break keyword can do this:

for (var x = 0; x < 3; x++) {
  var guess = prompt('what is my name?')

  if (guess.toLowerCase() === 'nick'){
    document.write('Good job guessing my name');
    break;
  } else {
    alert('good try, better luck next time');
  }
}

There's probably a neater way to do this but if you refactor your code a little this should work: 

for (var x = 0; x < 3; x++) {
  var guess = prompt('what is my name?')

  if (guess.toLowerCase() === 'nick'){
    document.write('Good job guessing my name');
    break;
  } else if (x == 2) {
    alert('good try, better luck next time');
  }
}
