This rule check if a component's name attribute matches its file name. By default it checks only .jsx files, but an additional option is provided to check both .jsx and .vue files

What category should the rule belong to?

• Enforces code style
• Warns about a potential error
• Suggests an alternate way of doing something
• Other (please specify:)

Provide 2-3 code examples that this rule should warn about:

// src/MyComponent.jsx
export default {
 name: 'MComponent', // this rule would warn of the mismatch between component's name

}
