Button tags require type.

[shadow7412]

Please describe what the rule should do:

All <button> tags require the type to be set.
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:

<button>Test</button>
<button class="btn btn-danger">Delete</button>

Additional context

Forgetting the type attribute on a button defaults it to being a submit type. This is nearly never what is intended, especially in your average one-page application.

type="button" stops the webpage from submitting the form, instead allowing the @click handler to work without the page reloading soon after.

type="submit" can be used explicitly to allow the default behaviour.
