 Given an array of objects representing people with a birth and death year, return the oldest person.
 
+Now that you've reached the final exercise, you should be fairly comfortable getting the information you need from test case(s). Take a look at how the array of objects is constructed in this exercise's test cases to help you write your function.

 ## Hints
 - You should return the whole person object, but the tests mostly just check to make sure the name is correct.
-- this can be done with a couple of chained array methods, or by using `reduce`.

 ## Debugging
 
-To debug functions, you can run the tests in the Visual Studio Code debugger terminal. You can open this by clicking the "Run and Debug" icon on the left or pressing `ctrl + shift + D`, then clicking JavaScript Debug Terminal. You will be able to set breakpoints as you would in the Chrome DevTools debugger. You can run `npm test exerciseName.spec.js` to then execute your code up until your breakpoint and step through your code as necessary. **NOTE**: To take advantage of the debugger, you **MUST** run the script in the debugger terminal, not the bash or zsh terminal.
