However, the displayed weather stayed the same \ud83d\ude32.<\/p>\n<p><\/p>\n<h2>The Solution<\/h2>\n<p>The problem was that the child component\u2019s state was set only once. To fix this, I used the useEffect hook to update the child\u2019s state when the parent\u2019s data changed.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/namastedev.com\/blog\/wp-content\/uploads\/2024\/06\/image-26.png\"><\/p>\n<p><\/p>\n<p><\/p>\n<h2>The Result<\/h2>\n<p>With this change, both the current and displayed weather updated seamlessly \ud83c\udf89.<\/p>\n<p><\/p>\n<h2>Conclusion<\/h2>\n<p>This experience taught me about state and props in React. The key is to use the <strong><em><u>useEffect hook <\/u><\/em><\/strong>to keep the child state in sync with the parent props.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>Props don\u2019t automatically update a child\u2019s state.<\/li>\n<li>Use the useEffect hook to sync state with props.<\/li>\n<li>Debugging can be frustrating \ud83d\ude24, but it leads to learning.<\/li>\n<\/ul>\n<p><\/p>\n<p><\/p>\n<p>What&#8217;s Next?<\/p>\n<p>We&#8217;re constantly improving our weather dashboard and would love to hear your thoughts.
