Nothing logged yet. Add LOG('foo', { bar: 'baz' }, ...) to your code to log something. The logs will also be available in the browser devtools/console.
The logged values need to be JSON serializable, because your code runs in a web worker. If something doesn't look right, try checking the console.
No markers yet. Add TIME('name') to your code to add markers.
When two markers have the same name, the duration between them will be calculated.
