I am getting errors saying that the comparisons are not valid, whats wrong with this?

I am a new coder skimming the basics of JavaScript, and was trying to follow this tutorial but could not get this to work. Any help would be appreciated :)

var userChoice = prompt("Do you choose rock, paper or scissors?")

var computerChoice = Math.random();
console.log(computerChoice);

if (computerChoice > 0 && < 0.33) {
  (computerChoice = "rock");
}
  else if (computerChoice > 0.34 && < 0.66) {
  (computerChoice = "paper");
}
  else (computerChoice > 0.67 && < 1) {
  (computerChoice = "scissors");
}
