Editing Cross-platform software (section)

=====Single codebase=====
This strategy relies on having one codebase that may be compiled to multiple platform-specific formats. One technique is [[conditional compilation]]. With this technique, code that is common to all platforms is not repeated. Blocks of code that are only relevant to certain platforms are made conditional, so that they are only [[interpreter (computer science)|interpreted]] or [[compiler|compiled]] when needed. Another technique is separation of functionality, which disables functionality not supported by browsers or OSs, while still delivering a complete application to the user. (See also: [[Separation of concerns]].) This technique is used in web development where interpreted code (as in scripting languages) can query the platform it is running on to execute different blocks conditionally.<ref>{{cite journal|last=Corti|first=Sascha P.|title=Browser and Feature Detection|journal=MSDN Magazine|date=October 2011|url=http://msdn.microsoft.com/en-us/magazine/hh475813.aspx|access-date=28 January 2014}}</ref>
