Upon starting a build using IL2CPPA Unity-developed scripting back-end which you can use as an alternative to Mono when building Projects for some platforms. More info
See in Glossary, Unity automatically performs the following steps:
Compiles Unity Scripting API code to regular .NET DLLs (managed assemblies).
Applies managed bytecode stripping. This step significantly reduces the size of a built game.
Converts all managed assemblies to standard C++ code.
Compiles the generated C++ code and the runtime part of IL2CPP with a native platform compiler.
Links the code into either an executable file or a DLL, depending on the platform you are targeting.
IL2CPP provides a few useful options which you can control by attributes in your scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
