Description

I haven't found any rule that complains about the following:

<Comp a={1}b={2}c={3}/>

And enforces space between props:

<Comp a={1} b={2} c={3}/>

Notice how it shall not affect the space before closing tag.

Is there a rule for it? If not, here it's my suggestion for it.

Research direction
This is a feature request for a new ESLint rule that enforces spaces between JSX attributes. To implement, study existing rules in the eslint plugin react repository, particularly those dealing with JSX spacing (e.g., jsx curly spacing). The rule should detect when multiple attributes appear consecutively without a space and suggest adding them, while preserving the space before the closing tag. The implementation involves adding a new rule file, tests, and documentation. See the rules directory at packages/eslint plugin react/lib/rules/ for examples.
