AWS Appsync $ctx vs $context in resolvers

Question

I understand that context is what ever name you define in your Lambda functions but when it comes to Appsync resolvers I'm a bit confused. I've seen both $ctx and $context being used in AppSync resolvers including in AWS docs. Some of AWS's own code generation tools like AWS Amplify CLI create resolvers that use both in the same code! I can't find anything in the docs explaining this. What's going on here?

AWS AppSync中的

$ctx和$context指的是同一Resolver Context。我们添加了$ctx作为$context的别名，以减少用户必须输入的字符数（{$ctx比$context短50％！）

选择$context或$ctx是个人喜好。在编写AWS AppSync解析器时，我更喜欢$ctx。
