Be Aware of the !-- script Bug

Lets say you have this string in a variable (case insensitive):

`etc etc etc<!-- etc etc<scRipT> etc`

This will break any html tag after it.

Or lets say you divided that into some variables:

const first = `etc etc etc <!--`;
const second = `anything`;
const third = `<script>`

This will also break the html page.

Therefore please carefully assign any string that contains

`<!--<script>`

or similar into a variable, if it is inside <script> tag.

Edit: The original title is changed

Feel free to ask any question related to this in the comments :)
