Prompt still not running

Question

<script>
    function numAleatorio(tamanho)
{
    var nums = '0123456789';
    var aleatorio = '';
    for (var i = 0; i < tamanho; i++) {
        var rnum = Math.floor(Math.random() * nums.length);
        aleatorio += letras.substring(rnum, rnum + 1);
    }
    var palpite = numAleatorio(1)
    var x = prompt("Escreva um número de 0 a 9","0");
    var numero = parseInt(x);
    if (numero > 9){
        alert("Tá trapaceando né?")
    }
    if (numero == palpite){
        alert("o meu palpite é "+ palpite)
        alert("acertei? haha!")
    }
    else 
    {
        alert("aaah você ganhou...")
    }
}</script>

Answer 1

One of the causes that might be preventing code execution has already been pointed out by @Isac: the method prompt returns a string. Therefore, if you want to test as a number, you can use the function parseInt to convert the string from the prompt to integer, as the name says.

The other cause that may also be preventing code execution, is that when you went to compare whether there is equality between the numero and the palpite, you used the assignment operator =, instead of the equality operator ==.

I hope I’ve helped!
