Function getAttribute

getAttribute<V extends AttributeValue = string, E extends Element = HTMLElement>(
target: null | Target,
name: AttributeName<E>,
): null | V
Attempts to get the attribute name from the target. If the value is found, it is coerced to a boolean if "true" or "false", a number if numeric, or the string value if a string. If not found, returns null.
Type Parameters
- V extends AttributeValue = string
  Type of value to return.
- E extends Element = HTMLElement
  Element representation of target.
Parameters
- target: null | Target
  Element, EventTarget, or CSS selector.
- name: AttributeName<E>
  Name of the attribute to get.
Returns null | V
Value of type V or null if not found.
Remarks
We're returning null, rather than undefined to match the Element.getAttribute API.

Throws
elements!InvalidElementError if the specified target wasn't found.
Example
HTML
```
<div
  id="example"
  role="slider"
  aria-valuemax="30"
  aria-label="Example"
  aria-disabled="false"
>
  ...
</div>
```
Code
```
const element = findElement("#example")!;

getAttribute(element, "aria-label");
// "Example"

getAttribute(element, "aria-valuemax");
// 30

getAttribute(element, "aria-disabled");
