// ==== Challenge 1: Write your own closure ====
// Write a simple closure of your own creation. Keep it simple!
function setName() {
let name = "Arkadiusz";
function setHobby() {
let hobby = "Gaming";
console.log(name + "is bored");
}
setHobby();
}
setName();
// ==== Challenge 2: Create a counter function ====
let count = 0;
const counter = () => {
// Return a function that when invoked increments and returns a counter variable.
count++;
return count;
};
counter();
counter();
counter();
counter();
counter();
// Example usage: const newCounter = counter();
// newCounter(); // 1
// newCounter(); // 2
/* STRETCH PROBLEM, Do not attempt until you have completed all previous tasks for today's project files */
// ==== Challenge 3: Create a counter function with an object that can increment and decrement ====
const counterFactory = () => {
// 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.
};
