This article describes live programming which is something that dates back to some of the older programmers. It's a common methodology that crops up often. It's not about the number of times it takes you to run something or finding spelling errors. Fixing spelling errors still counts as "running the first time" as long as you're not changing the structure of the code. This article describes the idea of an interactive programming environment with a single language for all problems. This method of development, as described in this article, is very common in industry but not very productive. It is still lot of trial and error and in that same time I can be doing something that I know I will do correctly.
