How to merge 2 objectId into one unique id?

Question

JavaScript

Hello.
Is there any way to make unique. id of 2x objectId
idea: md5( [objectId(abc), objectId(cba)].join(“”) )
but md5( [objectId(cba), objectId(abc)].join(“”) )
would be another hash .
How can you get the same regardless of the order in the array.?

Answer 1

Everything is possible, another question is why? uuid is unique by definition, composite keys are used in other cases, for example, when categorizing by country - region - city
