Function, Variable and Parameter Names

American spellings are used for all parts of the system, for instance applet parameters defining colours have names like loadingColor. However, documentation uses British spelling.

JavaScript functions and variables in Information Overlaid are given names where the words are joined by underscore (_) characters, such as easel_load_image. The first part is the name of the library, or group of libraries, from which the variable or function comes.

Callbacks, that is functions you can define to modify the behaviour of the system, all have _on_ in their name, for instance easel_on_image_end.

Applet parameters, which are given to the applet in the HTML of a page, have names runTogetherWithCapitals, for instance dataCopyrightUrl.
