[Node.js, Go] - Lambda function wording

In Nodejs realm does the term lambda exist, although the coding style looks like lambda it's referred to as “arrow functions” or “function expression” can this be verified and if so the documentation refer to a similar terminology?

https://docs.couchbase.com/go-sdk/current/howtos/distributed-acid-transactions-from-the-sdk.html#creating-a-transaction 
This is also a question for Golang, which refers to these as "function literals" 

Seems we are using this partial for both:
https://github.com/couchbase/docs-sdk-common/blob/release/7.0/modules/shared/partials/acid-transactions.adoc#creating-a-transaction

Looks like we need to make some of these references less generic depending on the SDK?
