Are you a Flash developer? This comparison chart is for you! This chart is a quick reference to get you up to speed on how to do everything you know in Adobe Flash with Corona SDK.
Flash ActionScript is inherently object-oriented, often making it difficult to do the simplest of things. Corona SDK is based on the Lua language, which is flexible, easy, and powerful.
