FinalExam/FinalExamQuestions/Problem 4/Problem4.md

+Problem 4 (40 points)
+In `problem4.js` you need to define a single endpoint, `/library` that needs to respond to a `get` request. It needs to handle the following query parameters:  
+`/library?sort=ascending`  
+If this is passed the server should respond with the data sorted by title in ascending order  
+`/library?sort=descending`
+If this is passed the server should respond with the data sorted by title in descending order 
+`/library?sort=ascending&byAuthor=true` 
+If this is passed the server should respond with the data sorted by author last name in ascending order  
+`/library?sort=descending&byAuthor=true`
+If this is passed the server should respond with the data sorted by author last name in descending order 
+`/library?filter=authorLastName`  
+If this is passed the server should respond with all the data associated with the authorLastName
+
+If no query params are passed then the server should respond with all the data in the array.  
+
+In `functions.js` you need to define the 4 functions that you will need to use to perform the different operations on the data.
+
+__HINT__ You may find the javascript String.prototype.split method helpful. It takes a separator as a parameter and returns an array of substrings based off of that separator. For example:  
+"How are you doing today?".split("o") returns: 
+[ 'H', 'w are y', 'u d', 'ing t', 'day?' ]
