useRef Hook in React
useRef is a React Hook that is used to store a value that persists between renders without causing the component to re-render when the value changes. It is also commonly used to access and interact with DOM elements directly. Syntax const reference = useRef ( initialValue ); For example: const count = useRef ( 0 ); What Does useRef Return? useRef() returns an object containing a property called…
const count = useRef ( 0 );
React updates the mutable reference but does not trigger a re-render. This behavior contrasts with useState, which utilizes a setter function and causes a re-render when the state is updated. useRef proves useful when UI does not require updates, such as preserving previous values or accessing DOM elements.
