[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

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.

Bắt đầu từ trang react.dev/learn được liên kết và tìm phần giải thích được làm nổi bật trong Quick Start. Xem lại phần diễn đạt xung quanh trong JSX và JavaScript, sau đó làm rõ sự khác biệt giữa các biểu thức bên trong dấu ngoặc nhọn và các câu lệnh if trực tiếp; trang này cần giải thích chính xác tại sao ví dụ được viết như vậy.
