How to make floodfill in html5 canvas?

Question

JavaScript

Hello! Can you please tell me how to implement something similar to FloodFill (delphi)? Those. we have a closed figure and a certain point inside it. We choose a color and paint over everything until we reach the border? The syntax is something like this:
