Good article about React hooks and memory leaks. Basically, your app probably has memory leaks. Doh!

Good thing to keep in mind for sure, but instantiating that `new BigObject()` on every render is the root cause of that specific issue.

Either instantiate once outside the component, or `const bigData = useMemo(() => new BigObject(), [])` and the problem goes away.

of course!  playing the devil's advocate, they were just making a point w/ an easy to reason about large object. If you have a large component, you can probably still effectively (accidentally) do the same thing w/ whole bunch of little objects

For sure. I wonder if/how this is gonna change once the React compiler is out 🤔
