This is because refs are not part of the component state. On the other hand, updating the value of a state variable with useState triggers a re-render of the component.<\/p>\n\n\n\nImage Source:<\/strong> Google Trends<\/figcaption><\/figure>\n\n\n\n<\/span>When to Use useRef vs useState<\/span><\/h2>\n\n\n\nTo choose between useRef vs useState, you need to consider the specific requirements of your project and how each hook aligns with those needs.<\/p>\n\n\n\n
<\/span>Let’s Know When to Use useRef<\/span><\/h3>\n\n\n\n\nAccessing DOM Elements:<\/strong> If your task involves direct manipulation of DOM elements, such as triggering animations, focusing on input fields, or working with third-party libraries, useRef is your ideal choice.<\/li>\n\n\n\nOptimizing Performance:<\/strong> When you need to fine-tune your application’s performance by avoiding unnecessary re-renders, useRef can be a game-changer.<\/li>\n\n\n\nNon-reliance on State Updates:<\/strong> Use useRef when your operation doesn’t depend on state updates. It’s perfect for actions that should remain unaffected by state changes.<\/li>\n<\/ol>\n\n\n\n<\/span>Also, When to Use useState<\/span><\/h3>\n\n\n\n\nState Management:<\/strong> Whenever you need to manage component state, handle user input, or create dynamic, re-rendering UI components, useState should be your first pick.<\/li>\n\n\n\nUser-Interactive Elements:<\/strong> useState shines when your project involves user-driven changes, such as form handling, UI toggling, and data updates triggered by user actions.<\/li>\n\n\n\nReusable Components:<\/strong> For building reusable and encapsulated components that maintain their state, useState is the way to go.<\/li>\n<\/ol>\n\n\n\n<\/span>Examples For Useref Vs Usestate<\/span><\/h2>\n\n\n\nIn this example, the inputRef ref is used to store a reference to the input element. The focus input function then uses the current property of the ref to focus the input element.<\/p>\n\n\n\n
