highlight.js | JavaScript syntax highlighter with language auto

I read through quill's guide for syntax highlighting but couldn't get it to work, as quill kept complaining about highlight.js not being loaded first.

I have tried numerous solutions online, but none have worked. I get a selector for language instead (which in my local project, when saved as html and reopened, also adds unnecessary p tags with language names).

Here is a sandbox https://codesandbox.io/s/importing-sass-in-vue-forked-skuss?file=/src/components/HelloWorld.vue

I imported highlight.js via cdn directly on index.html.

I have this line of code in almost every component file where I have subscribe to an observable returning from singleton service file.

destroy$ : Subject = new Subject()

I have the following code. It simply makes the python script formatted, with the colors using highlight.js.

I am writing copy button for code-blocks, but the button can not handle "copy" event.

The buttons are created with createElement method, and event added to the buttons with addEventListener to the buttons, before appending to the blocks, through foreach loop.
