Motivation

We do not currently support the whole of the AppSync @aws-appsync/utils package available on AWS. We would like some input on what functions are the most used by our community.

Instructions

Please add a comment to this PR indicating which functions you use when using AppSync, specifically in JavaScript resolvers from the @aws-appsync/utils package. If a comment already exists with your suggestion then please leave a 👍 on the comment, and we will use this to prioritise the functions that are most requested.
