Run Code in React Before Render

Read Original

This article discusses the misconception of running code before a React component renders. It explains that React does not wait for async operations and will render immediately. The guide covers proper state initialization (for arrays, objects, and lazy initialization) and recommends placing async actions like data fetching inside useEffect, after the first render. It also touches on handling loading states and using modern JavaScript operators like optional chaining for safer code.
