Hi,
I do not have any experience on react/jsx, but I was involved in many other Node.js and frontend projects.
When going through the react.dev tutorials, I cannot help asking the following questions. I consulted ChatGPT before posting, but I was not satisfied by its answers.
1. Is it really necessary to rename attribute class to className?
A common argument for that is class being a reserved keyword in JS. However, it's perfectly fine to pass it as a dict key.
Also, break-assignment can be renamed when catching class attribute in function arguments:
function Component({ class: className }) { ... }
Is there any other fundamental issue blocking the use of class as an attribute? Can we accept both class and className attributes in base DOM elements in a future version of react?
2. Why mixing children with other props?
// Instead of
function Component({ children, ...props }) { ... }
// Why not
function Component({ ...props }, ...children) { ... }
I just feel sad knowing that children works different as other keys in the same level...
I know there probably exist a ton of discussions on these topics, please feel free to shoot me links in case you know where to find them.
