Multi-part question - please use a), b), c), d) to identify your responses.

Given a server.js file that uses express (you do not need to write the express imports), write code to respond to the routes below as specified in each description. NOTE: all callback functions must be written in the new ES6 "Arrow Function"syntax:

a) Write route "/test"that can capture all verbs (GET, PUT, POST, DELETE, etc.) and responds with a 200 status code, making sure to also "end" the response without sending anything back.

b) Write "GET" route for a variable "num" ie: /employee/5 and responds with a JSON formatted string: {employeeNum: num} where num is the value passed in the url.(HINT: req.______.num).

c)Assuming our server.js is using the "path" module, write a "GET" route "/employeeDocs/training" and send the file "training.pdf" (located at the root of your application folder), causing the user's browser to prompt them to download it. (HINT: do not forget to include __dirname in your solution).

d) Write "GET" route "/employees" . This route will support optional queries:

"/employees?pay=PAY" which responds with a JSON formatted string: {message: PAY } (wherePAY is the value passed in the url). (HINT: req._____.pay).

"/employees?position=POSITION" which responds with a JSON formatted string: {message: POSITION} (where POSITIONis the value passed in the url). (HINT: req._____.position).

If there are no optional queries, the server should respond with a JSON formatted string: {message: "all employees"}.
