What happened?
I get this error in the browser console when using the debug toolbar to highlight views:
Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.
at showHints (<anonymous>:459:34)
at btn.parentNode.onclick (<anonymous>:514:17)
In the loop over sortedComments, the end variable gets shared between different iterations of the loop.
In some iterations, start is equal with childArray.length, so end is not given a new value and keeps the one from the previous iteration.
If the previous value was larger than start, this results in an attempt to read from beyond the end of childArray, so debugDiv.appendChild() is called with undefined.
Steps to Reproduce
app/Views/page.php:
<?= view('header') ?>
<?= $content ?>
<?= view('footer') ?>
app/Views/header.php:
app/Views/footer.php:
app/Views/inner.php:
any controller:
return view('page', ['content' => view('inner')]);
Render the view, then click on "Views" in the debug toolbar
Expected Output
No error
Anything else?
Using let start, end instead of var start, end seems to fix the issue by preventing the variables from "leaking" across iterations.
I intend to submit a PR that fixes this.
