In Playwright with TypeScript, imagine you have a function that returns a 'Locator' for an interactive element. This element could either be a 'Submit' button or a 'More Info' link, both of which need to be clicked, but the 'More Info' link also requires checking its 'href' attribute. How would you best handle such a scenario to perform actions specific to each type while maintaining type safety?
Declare the element variable as
'any' to allow for flexible interaction.
Use type assertion ('as`) to
cast the element to `Locator`
and then check its tag name.
Create separate functions for
handling buttons and links, calling the appropriate one based on a string parameter.
Utilize union types
(e.g., `Locator | Locator`) along with a type guard to differentiate and interact safely.
