Am I crazy, or is that code drawing every line twice?

I think it's drawing some lines twice, but I didn't think it's worth adding more lines to prevent it. Suggestions, anyone? Edit: I updated line 18 to let j = i + 1;

Well j = i + 1, and drop the equality test.

Nice! This is a fun demo btw, makes me want to play around with canvas. I've never really come across a need for it besides things like hacky camera implementations.

Glad to hear you enjoyed it!

If you’re iterating over a whole array and need the index, like in ll.15f., you can instead write

particles.forEach((particle, i) => {
  // loop body
})

There may be a performance hit (I haven’t tested it) because you’re invoking a function on each iteration. And it’s mostly a stylistic choice.
