You never tell React <em>how</em> to change the page; you describe what it should be now, and React works out the smallest set of changes that gets the screen there. The idea met a cool reception when Facebook released React in 2013; today React is the most used library of its kind. In Stack Overflow&rsquo;s 2026 Developer Survey, 42 percent of respondents said they had used it, second among web frameworks and technologies only to Node.js.<sup id="fnref:1"><a href="#fn:1" class="footnote-ref" role="doc-noteref">1</a></sup></p>
