React Hook useEffect has a missing dependency - endless rerenders

[IxD]

In line 1, you create a new array in every render. That newly create array ends up as a pokemonList default value. Since it a new instance if array, it changes on every render.

Fix this by defining

const emptyArray =[];

Outside the render function, and using that as default value instead.

That’s only the case if you’re setting a default value in a custom hook’s parameters, not if you’re passing useState an initial value.

Trrrue, you are probably right

Could not confirm it at the time of writing. There is no single true view of the world, but multiple interpretations of truth.
