Discussion on: How to fade in content as it scrolls into view

[Victor Uvarov]

Thanks I figured it out already. There were 3 problems.

• useRef() should be initialized with null and typed.

const domRef = useRef<HTMLDivElement>(null);

• the ref will be null for a second, so I just needed to have a local var in the first lines of the effect

const current = domRef.current;
if (!current) return;
