I just started learning javascript and after learning loops and if else i wanted to write a small program that's asked the user it's name and it is empty or its a number it will keep asking the user until it's a valid name. First if i write a string it will write to html but when program trying to run the loop it will fail to write the valid name.
var getName = prompt("What is your name ? ");
if (getName === null || !isNaN(getName)){
while (getName !== null || isNaN(getName)){
alert("Invalid name, please try again");
getName = prompt("What is your name ? ");
if (getName !== null || isNaN(getName)){
document.write("Hello ", getName);
}
}
}else {
document.write("Hello ", getName);
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>test</title>
<script type="text/javascript " src="script.js"></script>
</head>
<body>
</body>
</html>
can someone explain it to me why my code does not work after getting into loop and after entering a valid thing program still says "it's not a valid name try again"
when did i messed up. i am really bad at programming lol
