How Sarah isn't true? var name = "Trish"; function setName() { var name = "Sarah"; } setName(); alert(name);

var message = "Welcome!";
function setMessage() {
  message = "Go away!";
}
setMessage();
alert(message);//this will print, Go away, as it had var message, overwritten, the welcome to go away
//only one variable

var name = "Trish";
function setName() {
  var name = "Sarah";
}
setName();
alert(name);// if you see here, there are 2 variables, depending on the scope, outside the bloxks, one variable
//inside the function block, another variable
//function calls the setName, which brings in the newly declared name variable for the value of Sarah
//and then alerted
//var name = "Trish" is not used here
