  • I have tried restarting my IDE and the issue persists.
  • I have updated to the latest version of the packages.
  • I have read the FAQ and my problem is not listed.

Repro

In cases with strings, we may want to prefer that empty string "" is equivalent to nullish, and show a fallback in that case. There currently is no option to support customizing string behavior.

Example:

let emailAddress: string | null = getEmailAddress();
const link = "<a href='/'>" + (emailAddress || "---") + "</a>";

At a minimum, it'd be good to have a ignoreStrings option.
