// ==== Challenge 1: Write your own closure ====
// Write a simple closure of your own creation. Keep it simple!
const lastName = 'Bermudez'
function greet() {
const firstName = 'Ramses';
return `Hey there! My name is ${firstName} ${lastName}`
}
console.log(greet());
console.log(firstName); //Shouldnt work due to closure
/* STRETCH PROBLEMS, Do not attempt until you have completed all previous tasks for today's project files */
// ==== Challenge 2: Create a counter function ====
const counter = () => {
// Return a function that when invoked increments and returns a counter variable.
};
// Example usage: const newCounter = counter();
// newCounter(); // 1
// newCounter(); // 2
// ==== 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.
};
