Echo JS 0.11.0

Ok, but why does it take 100% of one CPU core?

Haha, probably because i'm using <table> 😅 Tried to keep it as simple as possible. Probably refactor soon for <canvas>

Maybe consider a web-worker that emits the change events, listening to a debounced method combined with requestAnimationFrame for render updates?

Probably overkill, since calculation is so simple – it's presumably more about table layout changes.. Should maybe try box-shadow instead of border for example.
