How to detect download and upload speed with Javascript

Question

I am looking to create a relatively simple connection speed test wherein the user clicks a button and we have them download a few files, and then once that is done, we then initiate an upload back to us.

I have a seen a lot of various answers and methods for doing this with Javascript, JQuery, etc. What is the best way to accomplish the goal? I am fairly new to Javascript and web programming in general.
