Wow...It is working perfectly fast...
This is something I could not do and you got to teach me this bluebird sometime...
And I agree, node.js can be a perfect solution. I will open a second task request for this.

There is one major issue to be fixed...
I think the arrays do not reset when the start button is pressed again.
When you change the name or date, it pushes the new data on the old one and on div you see old results + new added ones.
This will be a minor fix I guess.
Can you do it ?
