+/*
+Your tasks:
+1. Use a constructor function to implement a 'Car'.A car has a 'make' and a;
+'speed' property.The 'speed' property is the current speed of the car in
+  km / h;
+2. Implement an 'accelerate' method that will increase the car's speed by 10,
+and log the new speed to the console;
+3. Implement a 'brake' method that will decrease the car's speed by 5, and log
+the new speed to the console;
+4. Create 2 'Car' objects and experiment with calling 'accelerate' and;
+'brake' multiple times on each of them
+Test data:
+§ Data car 1: 'BMW' going at 120 km / h
+§ Data car 2: 'Mercedes' going at 95 km / h;
