[Suggestion]: Change the error message "Objects are not valid as a React child (found: object with keys {aaa, bbb}). If you meant to render a collection of children, use an array instead.

Summary

You get the error message above when you create a functional component and omit to surround the properties with curly braces {}.

The message should be more directive.

Details

I think everybody does this when they first create a component. Type the error in your search engine, and you will see thousands of people asking the same question. For the sake of argument I attempted to "use and array instead" and got even more mysterious messages.

I believe the error message should be more like (for a component called MyComponent ) :

MyComponent is a functional component, and as such groups together all properties from the JSX tag into a single object. To use those properties directly in the body of MyComponent , surround the list of properties with curly brackets, such as MyComponent({foo, bar}).

ソースファイルもテストも指定されていません。まず、このエラーメッセージがreact.devに属するのかReact runtimeに属するのかを確認し、その後、既存のメッセージとそのテストを見つけてください。functional componentsやJSX propsについてユーザーに誤解を与えず、実行可能な指針を示すメッセージになっており、担当範囲が明確になっていれば完了です。
