Drawing with mouse events using the DOM API. Adopted from MDN examples.
cd examples/js_dom_draw
v run main.v
This starts a veb server at http://localhost:3001/ and compiles draw.js.v to
draw.js before serving index.html.
You can also run it from the repository root:
v run examples/js_dom_draw/main.v
v -b js_browser examples/js_dom_draw/draw.js.v
Then open index.html in your favorite browser.
