Get point's y coordinate on svg path

Answer 1

If you know all the points of your path, I believe a more performant solution than stepping through the path might be to search the d attribute of your path for the specific x coordinate you are looking for. Then capture the y coordinate using regexp. The regexp could be used like so:

const regex = new RegExp(`${x} ((\d*.\d*))`)
const match = regex.exec(d)
