I know many languages that compilers are implemented in the same language:
– The C# Roslyn Compiler is implemented in C#
– The F# Compiler is implemented in F#

Now, I think that is possible for example implement the compiler of C# 6.0 in C# 5.0

Then my question is about the same version of the language, that is:

can a compiler of a language L be implemented in the same language L ?

I ask this because I hear that typescript compiler is implemented in typescript, but
there are no previous version of the typescript language.

Thanks in advance.
