Object.prototype.hasOwnProperty.call(null, 'foo') not caught by try/catch about js-interpreter HOT 5 CLOSED

Second bug caught.

Thanks for reporting these! All I need is the code snippet to be pasted into index.html (and pasted into the console for comparison). No need for a screenshot.

This is another one, involving isGetter:

try {
  var foo = {};
  if (true) {
    alert((foo.a || foo.b).c);
  }
} catch(e) {
  alert('caught ' + e.message);
}

More edge cases; JSON.parse(undefined):

try {
JSON.parse(undefined);
} catch (e) {
alert('caught');
}

First and third errors are now caught. Will deal with the second one tomorrow.

Great work Neil! Sorry to be the source of so many reports - especially given most blockly workflows probably won't trigger them! Is the format of the bug reports above the most useful to you, or can I do something to improve them?

Your demo page has been super-useful for tracking these down to produce minimal test-cases 👍
