I need help "debugging" an If/Else if/Else statement's syntax

I am creating a game of Rock, Paper, scissors on "Codecademy" so I am using simple JavaScript for this. There are four necessities for this simple code

• If computerChoice is between 0 and 0.33, make computerChoice equal to "rock".


• If computerChoice is between 0.34 and 0.66, make computerChoice equal to "paper".


• If computerChoice is between 0.67 and 1, make computerChoice equal to "scissors".


• Needs to be an If/Else If/Else statement

So basically, I need to change the value of the function "computerChoice" based on the value of the function "computerChoice".

    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 = scissors;
}
