Function Scope
JavaScript has function scope: Each function creates a new scope.
Variables defined inside a function are not accessible (visible) from outside the function.
Variables declared with var, let and const are quite similar when declared inside a function.
function varFunction() {
var message = "Hello"; // Function Scope
}
function letFunction() {
let message = "Hello"; // Function Scope
}
function constFunction() {
const message = "Hello"; // Function Scope
}
