Comparing performance of: toFixed(4) vs toPrecision(4).toString() vs (Math.round(*10000)/10000).toString(). Please note that Math.floor, Math.trunc and ~~ can't be used for accurate rounding
Replace path prefixes either by splitting and concatenating path parts or by looking up separators in the path.
