๐๐๐๐๐ญ ๐๐: ๐๐ญ๐ซ๐๐๐ฆ๐ฅ๐ข๐ง๐ข๐ง๐ ๐๐ ๐๐๐ฏ๐๐ฅ๐จ๐ฉ๐ฆ๐๐ง๐ญ React JS, a JavaScript library by Facebook since 2013, excels in creating reusable UI components and managing state efficiently. Its Virtual DOM enhances performance by minimizing direct DOM manipulations. With JSX for declarative syntax and a unidirectional data flow, React simplifies UI development. Introduced in React 16.8, hooks like `๐ฎ๐ฌ๐๐๐ญ๐๐ญ๐` manage state in functional components, while `๐ฎ๐ฌ๐๐๐๐๐๐๐ญ` handles side effects. `๐ฎ๐ฌ๐๐๐จ๐ง๐ญ๐๐ฑ๐ญ` shares values across components, and `๐ฎ๐ฌ๐๐๐๐๐ฎ๐๐๐ซ` manages complex state logic. `๐ฎ๐ฌ๐๐๐๐` preserves values between renders, and `๐ฎ๐ฌ๐๐๐๐ฆ๐จ` optimizes performance by memoizing expensive computations.
