    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Set up the board by clicking any piece then click the square you want to move it to. The first piece must be clicked twice. Capturing pieces works similarly.

wierd js (interper)

u/joeytwiddle

Very weird. (Replace eval with throw to see what is generated.)
u/joeytwiddle

But I see potential here for a useful mini language. What if R performed fillRect or L performed lineTo? Could you draw something?
