Open Source – Emoji Calculator
Want to calculate with Emoji instead of the tried and tested traditional +, -, divide and multiply signs? Why…
As a proof-of-concept, we were asked to come up with a “simple web based emoji calculator” (where the operators were emoji characters/symbols instead of the traditional +, – etc signs). The condition is that, apart from the frontend (powered by jQuery and Bootstrap), all of the code had to be developed by us – so this meant no using frameworks (such as Slim or Silex) or third party code. It also had to show quite a large degree of “best practice” usages: oh, and it had to be written within 4 hours: making what would be a very simple quick project into one that took the whole four hours to write a PSR-7 style “request/response” system, with MVC pattern usage, a container (following the PSR-11 container-interop style) and routing. After this we spent a few hours writing lots of unit tests for it and generally bringing it up to an even higher standard.
