+// METHODS OF ARRAYS
+/*
+  push(elem_list): Adds one or more elements to the end of the array, 
+                   and returns the new length of the array. 
+
+            pop(): removes the last element in the array, decrements the length,
+                   and the element that it removed
+                 
+unshift(elem_list): adds one or more elements to the beginning of the
+                    array and returns the new length of the array
+
+           shift(): Removes the first element in the array, decrements the 
+                    array length, and returns the element that it removed
+
+  join(seperator): when no parameter is passed, this method converts all the elements
+                   of the array to strings and concatenates them seperated 
+                   by commas. To change the seperator, you can pass this method 
+                   a string literal
+
+      toString():  Same as the join method without any parameter passed to it.
