Matching filled strokes aligned vertically

Two different paths: Nothing

Eventually the filled strokes will be misaligned because the jagged line has greater length

Twin paths: pathLength

The straight one is actually a flatten jagged line which has the same amount of nodes
Uses pathLength svg attribute. The pathLength value for both paths are set to 73.

Two different paths: pathLength

Uses pathLength svg attribute. The pathLength value for both paths are set to 73.

Two different paths: SVGGeometryElement.getPointAtLength()

Jagged line uses SVGGeometryElement.getPointAtLength() to match straight line
Not very dynamic. For instance it assumes the animation only goes on x axis
