Lambda Calculus basics in every language

Hello World in every language has been done many times. What about lambda calculus?

I love lambda calculus and want to see how one would implement the “core” of lambda calculus in every programming language (just booleans and church numerals). I think it’s fascinating to see how different languages can do this.

Only two languages are up so far (JavaScript and Racket).

What’s your favorite programming language? Would you like to contribute yours? If so, check out the GitHub repository: https://github.com/kserrec/lambda-core
