正確答案:
Explanation
* The innermost assignment to the loanAmount variable should be the highest.
* Local variables have local scope: They can only be accessed within the function.
Example
// code here can not use carName
function myFunction() {
var carName = "Volvo";
// code here can use carName
}
* A variable declared outside a function, becomes GLOBAL.
A global variable has global scope: All scripts and functions on a web page can access it.
Example
var carName = " Volvo";
// code here can use carName
function myFunction() {
// code here can usecarName
}
* The alert() method displays an alert box with a specified message and an OK button.
An alert box is often used if you want to make sure information comes through to the user.
