Please resolve me How enter "Name" with Javascript? Not applies Name to enter

Question

Example:
function myFunction( ){
var retVal=prompt("enter your name","your name here");
if(retVal === true)
{
document.write("what is your name?");
return true;
}
else
{
document.write("your name here:" + "retVal");
return false;
}
}

Answer 1

prompt returns string entered by user or returns `null` if cancel is pressed.

You should check whether returned value is null or not (don't check against `true`)

if(retVal === null) {
//your code
}

Also don't forget to call method:

myFunction()
