Not sure why that's happening for you? Seems to be working fine for me...

Thanks for the test @anuragakella. Note your example is using p5.js version: 0.7.1, but I checked it on CodePen with version 0.9.0, and it also works as expected.

So, I think this might be related to the p5 web editor. It must handle console output or how the code is run in some non-standard way. Try running my test code there: https://editor.p5js.org/nonsequitoria/sketches/6MS3iYNJG
