Meanings
-
(often, uncountable) Especially in computer programming, and in the names of brands and organizations: a style of typography in which several words are concatenated together without any spaces between them, with the first letter of each word (sometimes excluding the first word) capitalized.
In the SMIL 1.0 specification, test criteria were hyphenated (e.g., system-bitrate and system-screen-size). This was deprecated by the SMIL 2.0 specification in favor of camel case attributes to be consistent with other developing standards.
2001 September, Jennifer Niederst, “Introduction to SMIL”, in Lorrie LeJeune, Richard Korman, editors, Web Design in a Nutshell: A Desktop Quick Reference, 2nd edition, Sebastopol, Calif.: O’Reilly Media, →ISBN, page 457:RadioShack is an example of a company name that uses camel case. In some cases, technology uses camel case, such as VistaVision, which is a widescreen format for movies. It's little wonder that camel case appears in application code—everyone already knows how to use it. […] Microsoft and other industry leaders have modified the standard use of camel case. When you talk about camel casing for .NET, what you really mean is that the first letter of each word, except the first word, is capitalized. For example, if you want to create a variable that contains the background color for an object, you might call it backColor.
2009, John Paul Mueller, “Coding the Application”, in C# Design and Development (Expert One-on-One), Indianapolis, Ind.: Wrox Programmer to Programmer, Wiley Publishing, →ISBN, page 243:It's common practice to name private members in camelCase, that is with an initial lower case letter and a capital for the start of each word.
2003, Rob Birdwell [et al.], “Introduction to Objects”, in Beginning ASP.NET 1.0 with C#, Wrox Programmer to Programmer, Wiley Publishing, →ISBN, page 298:Type and attribute names, and occasionally variable names, are traditionally written using camel case (with the first word lowercased and subsequent words title-cased, like dateTime), although there are exceptions to this rule (such as anyURI and QName), and some people prefer hyphenated lowercase words (like local-name).
2004 January, Michael Brundage, “Practical Examples”, in XQuery: The XML Query Language, Boston, Mass.: Addison-Wesley, →ISBN, part III (Application), pages 195–196:Write element and attribute names in a style called "CamelCase." Elements reflecting an entity should be written in UpperCamelCase; elements and attributes reflecting a property should be written in lowerCamelCase.

CamelCase is a common way of writing variable names in programming. It allows the programmer or someone reading their code to easily parse long variable names. […] The key feature of camelCase is that it allows multiple words to be combined into one with a medial capital letter at the beginning of each original word. It is named camelCase because it looks a bit like the humps on a camel's back.
