Stack of Hearts

u/vain

Nice!
u/vain

Btw... shouldn't "[i%5]" be "[i%6]"? Else you could save 1 char. :) What do these three points mean you used here: "fillText([... ,'" ?
u/BriSeven

Whoops, you're right. The ... is the spread operator, it splits the string in a unicode friendly way, and assigns the individual characters to the enclosing array literal.
u/BriSeven

@vain do notifications work on dwitter?
u/BriSeven

the ... next to the string is actually a special case. more generally it works on anything that implements the "iterator protocol" which is lots of stuff, but mostly arrays and array like things.
