Document Why a "complex expression in the dependency array" Is a Problem

this is about the exhaustive-deps eslint rule, specifically her: https://github.com/facebook/react/blob/master/packages/eslint-plugin-react-hooks/src/ExhaustiveDeps.js#L779. i've been trying to find out why having a complex expression inside of the dependency array is bad, but haven't found anything saying why something like [err?.message] would cause issues. is there somewhere it's listed in the docs that i haven't seen?

先閱讀 packages/eslint-plugin-react-hooks/src/ExhaustiveDeps.js 中約第 779 行的 exhaustive-deps 規則實作，並檢視現有的 React 依賴陣列文件。說明為什麼 [err?.message] 這類複雜運算式會造成問題，並提供足夠的解釋，讓讀者理解這項規則；當適當的文件清楚涵蓋這項理由時，即表示完成。
