thanks! I think it's good that you also type in everything that isn't entirely relevant by hand (Css...) :-)
However, I avoided the any in Typescript:
"const sections: NodeListOf = document.querySelectorAll('.section');" and "let navLinks: NodeListOf = document.querySelectorAll('.navbar a');"
I also changed the following: When I click on a section link, the h2 element was hidden by the NavBar. This is very easy to solve with:
".section {
scroll-margin-top: 90px;
}"
in the app.component.scss.
Thank you for your feedback and for sharing your improvements! It's great to hear that you found the tutorial on implementing ScrollSpy in Angular helpful and took the initiative to refine the code further. Your approach to avoid using `any` in TypeScript by explicitly typing the NodeList as `NodeListOf` and `NodeListOf` is a good practice for maintaining type safety and code readability.
Moreover, your solution to the issue of the `h2` element being obscured by the NavBar using `scroll-margin-top` in CSS is an elegant fix. This CSS property is indeed a handy tool for adjusting scroll positions to account for fixed headers or navigation bars. It ensures that when you navigate to a section via a link, the target section's top is not hidden behind any fixed elements at the top of the viewport.
Your contributions not only enhance the user experience but also demonstrate a proactive approach to problem-solving in web development. These tweaks make the navigation experience smoother and more user-friendly, especially in a content-rich application.

Very useful
If I scroll, it want to snap at the next section. How to do that in angular and tailwind
Lets make it "any" to get rid off the error...... Typescript crying in the background :P
Haha Yes I totally understand. And it's never recommended to use any. But this video was not focused toward typescript. It was focused towards the logic and other topic so that's why I just tried to save time.
But thanks for highlighting this :)
