Naming in DataTables 1.10
DataTables 1.10 adds support for camelCase notation for its configuration options, with support for the old Hungarian notation syntax still included for backwards compatibility so your tables won't simply break when you update from an older version of DataTales.
Many of the DataTables extensions had configuration parameters and APIs which also followed the Hungarian notation pattern of DataTables 1.9-. In keeping with the transition to camelCase notation in DataTables core, many of the extensions have the ability to accept parameters in either Hungarian or camelCase style.
Please note that the Hungarian notation option is deprecated and will be removed in future versions of the extensions (on the extension's next major version update - i.e. 1.x to 2.x, although 2.x is not planned for a long time to come - plenty of life in the 1.x series still!). The documentation for the extensions will be updated to remove the Hungarian notation before that point.
A guide is available showing the camelCase equivalent of the Hungarian notation, including naming and API convention updates if you would like to see how to use the new naming scheme.
Hungarian notation is an anathema to many developers, however, when I wrote the first version of DataTables, the company I was working for then had strict coding standards that required the use of Hungarian notation, so I was "trained" in its use, hence why it is present.
