I think "below the first div" is the direct child of <Item> in LessonCard, which for me doesn't fix the issue. It only works with an extra DOM node for me.

Also, I occasionally see this error when toggling items quickly. It causes the whole page to freeze until the timeout.

It basically works how it would as a switch statement, but in a declarative and "lazy" way to support SSR.

For us, it’s not so much that the mobile and desktop UIs look substantially different, but that the data and props passed to subcomponents may differ. Below is an example of the API. We wanted it so that switching between mobile and desktop did not remount the “Card” or “NeedHelp” components.

Same energy
An image of a coin jar with the caption "A quarter a day for a year will get you $9,125". Underneath it is a comment from another user saying "A dollar a day is $365. U got some limited edition quarters or something?"

It's gotten particularly useful in React 19 for making a component compatible with both upfront data and streaming.
TypeScript code snippet showing a React component function that handles both Promise and non-Promise values. The function declares a component that accepts a 'value' parameter of type 'MaybePromise<string>', then conditionally resolves the value using React's 'use' hook if it's a Promise.

It doesn't entirely ignore the await. JavaScript will implicitly wrap the value in a fulfilled Promise and pause execution until the next tick.
JavaScript code that demonstrates async/await behavior with non-thenable values. It contains two lines of code followed by their console output. The first line defines and immediately executes an asynchronous function that logs the awaited string 'Hello'. The second line logs the string 'World'. The output shows that 'World' appears first followed by 'Hello', illustrating how awaiting a string still allows the second console.log to execute before the first one.
