how to choose random x,y coordinates of a polygon

I have a shape, a polygon. I have the x,y coordinates of the edges of this polygon.

I'd like to draw 50 circles of 10 pixel radius randomly in this shape.

How do I randomly choose a position in my polygon?

I'm doing this in canvas with javascript, but I don't need any actual code. Maybe some math equations or some direction would be enough

You'd get the whole area of the polygon , apply a rand function on it and draw the circles, if you need to avoid intersection you could create a 'collision' function. Perhaps this helps:
