File Names

[IsraaSulaiman]

1. In src, you named the file where you handled all routes by 'hanlderData'. I think it would be better if you named it handlers.
2. In the public folder, you have request.js, but this file does not only include the xhr request; it also includes handling events and dom manipulation. Either change the name to be relevant to the content or move dom manipulations to the dom file. I am with the second option.
