      Credit: Re-export from react-use

      React effect hook that ignores the first invocation (e.g. on mount). The signature is exactly the same as the useEffect hook.

      Usage

      import { useEffect } from "@lynx-js/react";
import { useUpdateEffect } from "@lynx-js/react-use";

const Demo = () => {
  const [count, setCount] = React.useState(0);

  useEffect(() => {
    const interval = setInterval(() => {
      setCount((count) => count + 1);
    }, 1000);

    return () => {
      clearInterval(interval);
    };
  }, []);

  useUpdateEffect(() => {
    console.log("count", count); // will only show 1 and beyond

    return () => {
      // *OPTIONAL*
      // do something on unmount
    };
  }); // you can include deps array if necessary

  return <view>Count: {count}</view>;
};

      Type Declarations
