// ==== Challenge 1: Write your own closure ====
// Write a simple closure of your own creation. Keep it simple!
const alfa = "WHATS UP";
function myFunction() {
console.log(alfa);
const beta = "NOTHING,MUCH";
function nestedFunction() {
console.log(beta);
const gama = "ALL RIGHT THEN";
function nestedAnotherOne() {
const delta = "BYE";
}
}
nestedFunction();
}
myFunction();
/* STRETCH PROBLEMS, Do not attempt until you have completed all previous tasks for today's project files */
// ==== Challenge 2: Create a counter function ====
// Return a function that when invoked increments and returns a counter variable.
function multiplier(factor) {
return function (x) {
return x * factor;
};
}
let doubler = multiplier(100);
console.log(doubler(100));
// Example usage: const newCounter = counter();
// newCounter(); // 1
// newCounter(); // 2
console.log("hello");
// ==== Challenge 3: Create a counter function with an object that can increment and decrement ====
const counterFactory = () => {
let alfa = 2;
let someObject = {
increment: function () {
++alfa;
return(alfa);
},
decrement: function () {
--alfa;
return(alfa);
}
};
return someObject;
};
let bla = counterFactory();
console.log(bla.increment());
// Return an object that has two methods called `increment` and `decrement`.
// `increment` should increment a counter variable in closure scope and return it.
// `decrement` should decrement the counter variable and return it. let test = counter();
// test.increment();
