    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)

Down to 99, to make room for clouds at both ends

u/richev

I'm very much a beginner here, and am still running out of characters :-) x.font="450px'";x.fillText('☁️ ☁️',90,1080)
u/stiaje

Instead of 1080, you can write 2e3 which is short for 2000.
u/stiaje

Or 1e3, I guess :)
u/stiaje

Also, because the dweet starts with with(x) you don't need to write x.fillText, just fillText, as long as you make sure to separate your statements with a comma instead of a semicolon!
