How many times have you seen this little squiggley in your code and you are sure it shouldn't be there? Happens to me quite a lot. Usually when I install a new package and TypeScript doesn't seem to pick it up. Well there is a quick way to fix it (if it really shouldn't be there).

While you are focused on a typescript file (.ts), open the command prompt cmd + shift + p. Type "restart" in the prompt and look for "TypeScript: Restart TS Server".

Now, assuming you don't have a type or lint error, you will be good to go again.
