IIFE example with closure

jsClosure3.js

// PROBLEM
for (var i = 0; i<=3; i++) {
    setTimeout(function(){
        console.log("I have: " + i + " apples");
    }, i*2000);
}
// > I have: 4 apples
// > I have: 4 apples
// > I have: 4 apples

// SOLUTION
// You close the variable i (index) on line 4 with the parameter of the anynomous function on line 2
for (var i = 0; i<=3; i++) {
    function(i) {
        setTimeout(function(){
            console.log("I have: " + i + " apples");
        }, i*2000);
    })(i); // You call the function to execute here immediately
}
// > I have: 1 apples
// > I have: 2 apples
// > I have: 3 apples
// > I have: 4 apples
