### Why is this important?
Sometimes, JavaScript event handlers are added to page elements to simulate links, such as by using the `"onclick"` property on a `<span>` or `<div>`.
However, this can make it difficult for user agents to recognize the content as a link.
People may be unable to tab to the link using their keyboard, and it may be hard to understand what type of behavior to expect from the interactive controls.

### What to do
* Do not use scripts to emulate an HTML link wherever possible. Use `<a href>` or `<area>` to implement links.
* **Or**, if scripting must be used, add the attribute `role="link"` to the element and [implement keyboard accessibility](https://www.ibm.com/able/requirements/requirements/#2_1_1)

* [Failure F42: When emulating links](https://www.w3.org/WAI/WCAG22/Techniques/failures/F42)
### Who does this affect?
* People who rely on keyboard control
* People using a screen reader, including blind, low vision, and neurodivergent people
