React JS PureComponent and React memo
Показать описание
Hello Dev's, I spoke about the React JS PureComponent and React memo.
PureComponent is a class component provided by React that performs a shallow comparison of props and state to determine whether a component should re-render. If the props and state of a PureComponent remain the same between renders, it will not re-render, optimizing performance.
In some cases, they can lead to unexpected behavior if not used correctly, such as when dealing with deeply nested objects or functions passed as props.
It's essential to understand their behavior and use them judiciously where they provide real benefits.
