Answer 1

Change your calling method from

<script src="src/testing.js"></script>

to

<script src="../src/testing.js"></script>

but, I'm not sure in using Flask, maybe this can help you : https://stackoverflow.com/a/30011819/14963473

Import in html file seems correct. Maybe it's not the problem. Try to add on the beginning of js file:

console.log('ok');

And check if it will show in console.
