Learning to code in a day, the premise seems a little far fetched, so I was certainly intrigued by the event at Decoded in London.
With the breadth of possibilities of coding so large the focus of the day was on the specifics of creating an app that incorporated location data. Even this reduction in focus seems like a mammoth task, especially considering the course is not aimed at people with previous coding experience. In fact it is billed as aiding new comers in obtaining these skills in a day.
So with zero prior experience, is it possible to enable someone to create a location based app within a day? The quick answer is yes. Everyone on the course successfully created a location based app.
