React was already a powerful JavaScript library for building user interfaces. This (<code class=\"\" data-line=\"\">useState<\/code>,\u00a0<code class=\"\" data-line=\"\">useEffect<\/code>, and\u00a0<code class=\"\" data-line=\"\">useContext<\/code>) transformed the way we manage state, side effects, and shared logic within functional components\u2014making class components almost obsolete.<\/p>\n<p>Whether you\u2019re building a basic counter or a full-stack application, understanding <strong>useState in React<\/strong>, <strong>useEffect in React JS<\/strong>, and <strong>useContext<\/strong> is essential.<\/p>\n<h2>\ud83d\udd0d What Are React Hooks?<\/h2>\n<p>Hooks are built-in functions that let functional components access React features like state, lifecycle, and context. Previously, only class components could handle these. Now, with hooks, we write cleaner, more readable code with fewer lines.<\/p>\n<p>Hooks must follow two basic rules:<\/p>\n<ul>\n<li>Only call hooks at the top level of a component or custom hook <strong data-start=\"53\" data-end=\"122\">Always use hooks at the top of your React function or custom hook<\/strong>\u2014never inside loops, conditions, or nested functions.\n<ul>\n<li><strong data-start=\"114\" data-end=\"122\">Why?<\/strong><br data-start=\"122\" data-end=\"125\" \/>React uses the <strong data-start=\"140\" data-end=\"163\">order of hook calls<\/strong> to track state across renders.<\/li>\n<li>React needs to run hooks in the <strong data-start=\"121\" data-end=\"135\">same order<\/strong> every time.<br data-start=\"147\" data-end=\"150\" \/>If you put them inside an <code class=\"\" data-line=\"\">if<\/code> or loop, React gets confused and breaks.<\/li>\n<\/ul>\n<\/li>\n<li>Only call hooks from React functions (components or custom hooks) <strong data-start=\"182\" data-end=\"241\">Only call hooks inside React components or custom hooks<\/strong>, not in regular JavaScript functions.\n<ul>\n<li><strong data-start=\"651\" data-end=\"659\">Why?<\/strong><br data-start=\"659\" data-end=\"662\" \/>Hooks rely on React\u2019s internal render system. If you call them in normal JS functions, React has no way to manage their state, leading to unexpected behavior.<\/li>\n<li>Hooks only work inside <strong data-start=\"299\" data-end=\"335\">React components or custom hooks<\/strong>.<br data-start=\"336\" data-end=\"339\" \/>Using them in normal functions won\u2019t let React track or update them properly<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<blockquote><p>Hooks need a clear, safe place to live \u2014 always at the top, always inside React.<\/p><\/blockquote>\n<figure id=\"attachment_9300\" aria-describedby=\"caption-attachment-9300\" style=\"width: 1536px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-9300\" src=\"https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks.png\" alt=\"react hooks , useContext , usestate in react , useeffect in react js\" width=\"1536\" height=\"1024\" srcset=\"https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks.png 1536w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-300x200.png 300w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-1024x683.png 1024w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-768x512.png 768w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-332x221.png 332w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-664x443.png 664w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-688x459.png 688w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-1044x696.png 1044w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/07\/React-Hooks-1400x933.png 1400w\" sizes=\"(max-width: 1536px) 100vw, 1536px\" \/><figcaption id=\"caption-attachment-9300\" class=\"wp-caption-text\">Hooks React Js<\/figcaption><\/figure>\n<hr \/>\n<h2>\ud83d\udfe2How to Use the useState in React<\/h2>\n<p>useState is a Hook that lets you add state to functional components<\/p>\n<p><code class=\"\" data-line=\"\">useState<\/code> lets your React component <strong data-start=\"144\" data-end=\"164\">remember a value<\/strong> (like a number or text) and <strong data-start=\"193\" data-end=\"206\">change it<\/strong> when needed \u2014 like a memory for your UI.
