初学者 JS 标识符错误

Question

I am getting an identifier error on the first 'else if'. How come, and why dont i get another error for the second 'else if'?

<p id="user"></p></p>
<p id="rock"></p>
<p id="paper"></p>
<p id="scisors"></p>
<p id="check"></p>
<script>
var userChoice = prompt("Do you choose rock, paper, or scissors?");
document.getElementById("user").innerHTML=(userChoice);
var computerChoice = Math.random();
if (computerChoice <=.3399){
document.getElementById("rock").innerHTML=("rock");
document.getElementById("rock").innerHTML+=(computerChoice);
};


else if (computerChoice >=.34<.67){
document.getElementById("paper").innerHTML=("paper");
document.getElementById("paper").innerHTML+=(computerChoice);
};

else if (computerChoice >=.67){
document.getElementById("scisors").innerHTML=("sciscors");
document.getElementById("scisors").innerHTML+=(computerChoice);
};

Answer 1

else if (computerChoice >=.34<.67){
document.getElementById("paper").innerHTML=("paper");
document.getElementById("paper").innerHTML+=(computerChoice);
};

Is likely whats intended... The problem is here:

else if (computerChoice >=.34<.67){

You cant just have two operators together... You can acomplish this in two ways:

AND Operator:

else if (computerChoice >=.34 && computerChoice<.67){
document.getElementById("paper").innerHTML=("paper");
document.getElementById("paper").innerHTML+=(computerChoice);
};

OR OPERATOR

else if (computerChoice >=.34 || computerChoice<.67){
    document.getElementById("paper").innerHTML=("paper");
    document.getElementById("paper").innerHTML+=(computerChoice);
    };

Semi-colon Error:

if (computerChoice <=.3399){
document.getElementById("rock").innerHTML=("rock");
document.getElementById("rock").innerHTML+=(computerChoice);
};


else if (computerChoice >=.34<.67){
document.getElementById("paper").innerHTML=("paper");
document.getElementById("paper").innerHTML+=(computerChoice);
};

else if (computerChoice >=.67){
document.getElementById("scisors").innerHTML=("sciscors");
document.getElementById("scisors").innerHTML+=(computerChoice);
};

You cant have those semicolons before the else if statement as @squint said in the comments below.. Hope this helped
