 // ==== Challenge 2: Implement a "counter maker" function ====
-const counterMaker = () => {
+let count = 0;
+const counterMaker = (limit) => {
   // IMPLEMENTATION OF counterMaker:
   // 1- Declare a `count` variable with a value of 0. We will be mutating it, so declare it using `let`!
   // 2- Declare a function `counter`. It should increment and return `count`.
   //      NOTE: This `counter` function, being nested inside `counterMaker`,
   //      "closes over" the `count` variable. It can "see" it in the parent scope!
   // 3- Return the `counter` function.
+  // let count = 0;
+  function counter() {
+    count++;
+    return count;
+  }
+
+  return counter();
 };
 // Example usage: const myCounter = counterMaker();
+// const myCounter = counterMaker();
+// const myCounter = counterMaker;
 // myCounter(); // 1
 // myCounter(); // 2
+console.log(counterMaker())
+console.log(counterMaker())
+console.log(counterMaker())
+

 // ==== Challenge 3: Make `counterMaker` more sophisticated ====
 // It should have a `limit` parameter. Any counters we make with `counterMaker`
