Mental Model of Use Effect

This article addresses a common challenge in React development: the mental model for the useEffect hook's dependency array. It explains why developers should not treat the array as a conditional to constrain effect execution, which leads to stale values and bugs. Instead, it advocates for including all dependencies and moving conditional logic inside the effect callback, providing code examples to illustrate the correct pattern and avoid ESLint warnings.
