 When calling `toMatchSnapshot()`, we store all snapshots in a formatted snap file. That means we need to escape some characters (namely the double-quote `"` and backtick `` ` ``) in the snapshot string. Meanwhile, you might lose the syntax highlighting for the snapshot content (if they are in some language).
 
-To improve this case, we introduce [`toMatchFileSnapshot()`](/api/expect#tomatchfilesnapshot) to explicitly snapshot in a file. This allows you to assign any file extension to the snapshot file, and making them more readable.
