Quick Read : Vala is an object-oriented programming language with a self-hosting compiler that generates C code and uses the GObject system.
When it comes to compiling part, Vala doing something wonderfully different. The Vala source code is first translated to the equivalent C code, and then the resulting C code is compiled to an executable file using the standard C compiler.
Whether you are someone who works with C/C++ code or someone who works with C# and .NET languages, Vala is something you need to take a look at.
