 Supported languages

-There are two versions of WPILib, one for each of the two officially-supported text-based languages: WPILibJ for java, and WPILibC for C++.  A considerable effort is made to maintain feature-parity between these two languages - library features are not added unless they can be reasonably supported for both Java and C++, and when possible the class and method names are kept identical or highly-similar.  While unofficial community-built support is available for some other languages, notably `python <https://robotpy.readthedocs.io/en/stable/>`__, this documentation will only cover Java and C++.  Java and C++ were chosen for the officially-supported languages due to their appropriate level-of-abstraction and ubiquity in both industry and high-school computer science classes.

 In general, C++ offers better high-end performance, at the cost of increased user effort (memory must be handled manually, and the C++ compiler does not do much to ensure user code will not crash at runtime).  Java offers lesser performance, but much greater convenience.  New/inexperienced users are strongly encouraged to use Java.
