Docs: Add FAQ about ts-expect-error and ts-ignore not doing anything #9499
Description
Before You File a Documentation Request Please Confirm You Have Done The Following...
- I have looked for existing open or closed documentation requests that match my proposal.
- I have read the FAQ and my problem is not listed.
Suggested Changes
Anecdotally, I get this question multiple times a year: "why isn't my // @ts-ignore stopping lint errors?". A lot of users don't understand the difference between their linter and their type checker. Example: #9476
Now that we have separated-out FAQs, I think it'd be good to add an entry to the TypeScript FAQs about this. I could explain what the difference is, and have links to the docs for each tool.
