Difference between type and issuetype in JQL Edited

[Jack Nolddor -Sweet Bananas-]

Someone can tell me the difference if any between type and issuetype field on JQL?
I have same question with key and issuekey fields..., are they different in any way?

It's not well-documented, but there are a handful of "aliases" in Jira.  Key is an alias for issuekey, and type is an alias for issuetype.  You've spotted the two main ones!

The aliases can be clobbered - you can create custom fields with the same name which then become the first place Jira looks when you type in the alias, but I'd try to avoid doing that in every case, as it just confuses your humans.

There is not difference.
