Overview

This issue focuses on testing the JS/TS implementation of inlay hints. While testing, please also open issue for issues you notice with the implementation of inlay hints themselves as well

This is more of an exploratory test item. Just give the new inlay hints a try and report any issues you notice

Testing

1. Make sure you are using the latest TypeScript nightly in your workspace
2. Enable the various typescript inlay hints. You can search typescript inlay in the settings to find them.
   There are similar settings for JavaScript

Things to try

• Try browsing around the codebase to confirm that the hints show up where you'd expect
• Try editing some code to verify the inlay hints are updated correctly
• Try toggling various inlay hint settings and making sure the inlay hints are updated correctly
