+The function in this code takes two parameters - the callback function and `this` argument. We assign `this` to a new variable called array.
+We use forEach to loop over the calling array because forEach will skip the empty elements. We call the callback function using the `.call` method
+so that we can pass the this argument. We assign the output of the function to the index in the output so that the output has the corresponding
+empty elements too. For example, if `this` has empty elements at index 2 and 4, the output too will have empty elements at the same indices.
 
-There is no solution yet.
+```javascript
+  Array.prototype.myMap = function(callbackFn, thisArg) {
+  const array = this;
+  const output = [];
