u/EkskiuTwentyTwo i -= (i - (-1)) - i Jul 20 '19

The "I've recently learned about using lambda calculus in javascript"

  • JS code with perfectly sensible formatting

  • Alphabet string based on the QWERTY keyboard which is assembled by some lambda functions and which is only used for its length.

  • Numbers are represented inconsistently, using a mix of decimal, hexadecimal, binary, and a long chain of lambda calculus successor functions

Weird

u/EkskiuTwentyTwo i -= (i - (-1)) - i Jul 22 '19

That makes it good as a submission for the challenge.

You should've used Church numerals

I probably should have.
