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?

首先阅读 packages/eslint-plugin-react-hooks/src/ExhaustiveDeps.js 中第 779 行附近的 exhaustive-deps 规则实现，并查阅现有的 React 依赖数组文档。说明为什么 [err?.message] 这样的复杂表达式会带来问题，并提供足够的解释，让读者理解该规则；当相关文档清楚地涵盖这一原因时，即视为完成。
