the word coding is so annoying when it's used as a one-fits-all sort of thing, it's like when people use the word literally instead of figuratively
As it is, I'm comfortable using the term to denote any activity that programmatically and logically instructs a computer to take a certain sequence of actions. C? Coding! Java? Coding! JavaScript? Coding! CSS? Coding! Excel columns? Coding! Ctrl-h and a regex selector? Coding! It's coding all the way down!
