In the AWS Appsync resolver, is it `$util.` or `$utils.`?

Question

The AWS Appsync documentation seems to use $util. and $utils. interchangeably. Are they actually different, or synonyms of the same thing?

Best example is the the resolver transformation helpers documentation page where they appear side by side...

Answer 1

Yes, you can do both. It's like ctx and context, they are interchangeable.
