 Answer the following questions:
 
 What does `console` store?
+    ------------ Is an object Js which contains methos and properties for logging information,    displaying errors, warnings, debugging in the browser.
+
 What does the syntax `console.log` or `console.assert` mean? In particular, what does the `.` mean?
+    ------------ the dot notation between `console.log` or `console.assert` is the access to method(function) store within the console object. 
+
+    ---------- eg. With the . operator, we can access the properties in each object within the students array, allowing us to check or modify what’s stored in each object.

     d) Interpret line 4, what does the expression assigned to totalMinutes mean?
 
-        -------- This line is taking the leftover remainder in remainingMinutes and leaving just the
-            total amount that we can divide perfectly in whole number to see how many minutes we have.
+        -------- This line subtracts remainingSeconds from movieLength to remove the leftover seconds.
