描述

This would produce a warning:

<span> { tab.title } </span>

as it produces 3 <span> DOM nodes (typically not wanted)

This wouldn't:

<span>{ tab.title }</span>

研究方向
Explore the existing rules in eslint plugin react (e.g., jsx indent, jsx curly spacing) for patterns on implementing JSX lint rules. Create a new rule file that uses the JSXElement visitor to check for spaces inside JSXExpressionContainer. Specifically, detect when there is a whitespace node between the opening brace and the expression or between the expression and closing brace. Add the rule to the rules index and write test cases including the positive and negative examples from the issue. Consider using eslint plugin react's built in utilities for handling JSX.
