There are many interpretations of this work, and unfortunately the author was alive long enough to write much about it and react to some of those interpretations.
It is my personal opinion that an artist is not a critic, and should not try to be, they should sit back and not try to explain their work. Because their words have a huge impact on how people enjoy it. And usually only hurts people's enjoyment and interpretation.
Therefore, I will not write any of what he has said about it, but I will say it is available if you want to ignore the joy of building your own interpretation. I will say it is simply a beautiful painting, painted with hints of impressionism, expressionism, even possibly cubism. This work is way ahead of its time, and was considered by some at the time to be the most beautiful American painting ever.
Yes, but only because it gives you a link to where that was run. Click the link to the right with filename:lineNumber, and it will open the sources tab to that line. Set a breakpoint and rerun to pause there, then step through the code's execution.
Of course, if you're using minified or processed code, this will be more difficult, in that case figure out how to do it in VS Code.
