Tangi is an attempt of 2 teenagers (@nothendev AKA noth and @whynotdogie AKA mizu) to develop their own programming language.
You could count it as a toy programming language because it does not serve any actual purpose beyound just having a laugh trying to make a working compiler.
If you look at the features and syntax it looks like an amalgamation of Zig and Rust with several slightly confusing features like @implode(); (don’t ask me, I do not know what it does either) and context.
