    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.

Messing around with tagged templates for a function call with multiple arguments

u/joeytwiddle

#trick Try console.log`...` The first arg is ['', '']

Proof-of-concept of using valueOf to prevent function call parenthesis (()) to save space when a function is used at least 5 times.

Interesting hack! Basically, this is c.width|="Right-to-left Override unicode character goes here";for(i=9;i--;)x.fillRect(400+i*100+S(t)*300,400,50,200)
u/akm

u/iverjo exactly! It took me a little while to find a place to put the character and still have valid js

WOAH. How do you even copy and paste the special character?

You've reached the end.
