### What it does

Use [`.dataset`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/dataset) on DOM elements over `getAttribute(…)`, `.setAttribute(…)`, `.removeAttribute(…)` and `.hasAttribute(…)`.

### Why is this bad?

The `dataset` property is a map of strings that contains all the `data-*` attributes from the element. It is a convenient way to access all of them at once.

### Examples

Examples of **incorrect** code for this rule:

```javascript
element.setAttribute("data-unicorn", "🦄");
```

Examples of **correct** code for this rule:

```javascript
element.dataset.unicorn = "🦄";
```

## How to use

## Version

This rule was added in v0.0.18.
