[Suggestion]: Correction of misleading explanation in react.dev/learn (Quick Start)

Summary

In the image above, the highlighted text implying that if statements don't work in JSX is misleading. As this is a resource that will be used by a lot of developers looking to learn React, I believe it would be beneficial to the community to clarify the information that was intended to be passed on to readers

Details

As stated earlier in the page—code inside the curly braces is actually JavaScript. In the context of the highlighted text one could be led to believe that using if statements in a JSX file simply won't work or using it inside the curly braces also won't work which are both inaccurate. It is important for someone new to JSX to understand that the code inside the curly braces is supposed to be an expression.

Simply explaining that the js inside the curly braces must be an expression that returns a value, in this case—a markup should help the user better understanding why we shouldn't use an if statement directly in there.

Thank you for your time.

Beginne auf der verlinkten react.dev/learn-Seite und finde die hervorgehobene Erklärung in Quick Start. Überprüfe die umgebende JSX- und JavaScript-Formulierung und stelle dann den Unterschied zwischen Ausdrücken innerhalb geschweifter Klammern und direkten if-Anweisungen klar; die Seite sollte korrekt erklären, warum das Beispiel so geschrieben ist.
