A bird, perplexed “is certainly a lovely sentence when preceded by its own quotation.” is certainly a lovely sentence when preceded by its own quotation.


My name is William Lewis, and I'm a programmer living in upstate South Carolina. I'm primarily interested in the design and development of user interfaces, and I greatly enjoy programming in JavaScript. I'm also intrigued by programming language design and semantics, the foundations of mathematics and computing, visual arts, and recreational math.

If you're interested, please take a look at my recent work, my CV, or my GitHub profile.

Recent Work

  • tm is a Turing Machine editor and simulator. It's written in TypeScript using React, Redux, and Redux-Saga, and it features an easy to use drag-and-drop interface, unbounded tape, some clever trickery with b├ęzier curves, and more. Try it out at wjlew.is/tm, or see a video of it in action here.
  • ramo is a port of miniKanren to JavaScript. MiniKanren (and, by extension, ramo) provides a number of abstractions for programming with relations. Relations are generalizations of functions that allow for some pretty eccentric and mind-bending behavior. For a small taste, check out the solution to the famous "Zebra Puzzle" in the documentation.
  • blox is an unconventional "hello world" experiment in the domain of networked multiplayer systems. Clients dispatch Redux actions over a WebSockets connection to a server-side store; a reducer on the server generates world updates and broadcasts them to all clients. The result is a nearly seamless system that works surprisingly well. Try it out here.
  • brief-cases brings some of the best aspects of algebraic datatypes to JavaScript in a tiny and easy-to-use package. It is particularly useful when working with "functional" datatypes, syntax trees, or any other kind of discriminated union.
