+//     Array Method: spread operator (...)
+//
+// SYNTAX ////////////////////////////////////////////////////////////////////////////////////////////////////
+//
+//      for function calls:
+//          myFunction(...iterableObj);
+//
+//      for array literals or strings:
+//          [...iterableObj, '4', 'five', 6];
+//
+//      for object literals:
+//          let objClone = { ...obj };
+//
+// SUMMARY ///////////////////////////////////////////////////////////////////////////////////////////////////
+//
+//      • "..." spread operator is used combine arrays.
+//      • "..." spread operator is similar to the concat method.
+//      • "..." spread operator "spreads" all of the combined elements of the array individually.
+//      • To create a new array using different arrays using the spread operator, eclare a new array THEN
+//        inside the new array we are adding the individual elements of the first and second arrays.
+//      • The spread operator allows you to have greater flexibility than concat method, for example you could
+//        add another element to certain parts of the array besides
+//
