- :gear: This rule is included in `"plugin:lodash-template/recommended-with-html"` and `"plugin:lodash-template/all"`.

## Rule Details

This rule reports duplicate attributes.

When duplicate arguments exist, only the last one is valid.
It's possibly mistakes.

```html
<% /* eslint "lodash-template/no-duplicate-attributes": "error" */ %>
<!-- ✓ GOOD -->
<div
  foo="abc"
></div>

<!-- ✗ BAD -->
<div
  foo="abc"
  foo="def"
></div>
```
