A variable in a programming language is sait to be camelCased when all words but the first are capitalized. This practice contrasts with the C tradition of either running syllables together or marking syllable breaks with underscores; thus, where a C programmer would write thisverylongname or this_very_long_name, the camelCased version would be thisVeryLongName. This practice is common in certain language communities (formerly Pascal; today Java and Visual Basic) and tends to be associated with object-oriented programming.

Compare BiCapitalization; but where that practice is primarily associated with marketing, camelCasing is not aimed at impressing anybody, and hackers consider it respectable.
