+  This exercise may look familiar!

+
+  After you complete the exercise, compare your solution to your previous one.

+  This exercise was also in JS1 week 3, but you didn't know about objects yet.
+  It's more clear with objects than with arrays!
+  Feel free to look at your solution to that one to help you out - you already did this once!
+
+  -----------------------------------------------------------------------
+
+  Write a function journeyPlanner that:
+
+  - Accepts two paramters:
+    1) An object where the keys are locations and the values are arrays of the transportation modes you can use to get there.
+       e.g.
+       {
+           Angel: ["tube", "bus"],
+           "London Bridge": ["tube", "river boat"],
+       }
+
+    2) A string containing a transport mode
+       e.g. "bus"
+
+  - Returns an array of where I can go if I only want to use a specific mode of transport.
+
+  NOTE: Only the location names should be returned, as strings.
+
+  When you finish the exercise, think about how this solution is different to your last solution.
+  What's better about each approach?
