// ==== Challenge 1: Write your own closure ====
// Write a simple closure of your own creation. Keep it simple!
function speak(word) {
const slang = word;
console.log(`${slang} my man`);
function firstName(name) {
const nickname = name;
console.log(`${slang} ${nickname}`)
}
firstName('habatchi');
}
speak('Yo');
// ==== Challenge 2: Create a counter function ====
const counter = (function(count) {
return function() {
count += 1;
return count;
}
}(0));
console.log(counter());
console.log(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.
};
