https://nodejs.org/api/cluster.html#cluster_worker_exitedafterdisconnect

Set by calling .kill() or .disconnect(). Until then, it is undefined.

The behaviour you describe is exactly what is documented. Neither kill() or disconnect() was called in your situation, the worker called exit(), so exitedAfterDisconnect is false.

But shouldn't it be undefined as documented. .kill() or .disconnect() has not been called

Should we fix it at the documentation level or fix the code?
I can make PR for any of the above two case

It's repeatedly normalized from truthy/falsy to true/false: worker.exitedAfterDisconnect = !!worker.exitedAfterDisconnect. I'm not sure about the history of this. Can you troll the git history to see why this occurs?

I strongly suspect current behaviour is an improvement, but the docs need updating.

Also, I wonder, is the initial value false? If not, it probably should be.

Yeah I checked out the git history to this PR #3743
Here .suicide was replaced by .exitedAfterDisconnect but the truthy/falsy to true/false was retained and documentation was updated too but not anything about false. truth/false seems suicide behaviour.

Yeah, it was an improvement over .suicide
IMO docs and the code both need an update, it should be true or false, and the change reflected in the docs. If you approve I can create a PR for the fix of this.

cluster: default value of exitedAfterDisconnect changed to false
e9a3db6 
The defaul value of worker.exitedAfterDisconnect is undefined. If the
worker dies on its own the value is changed to false and doesn't
remains undefined. While the documentation just mentions 'Set by
calling .kill() or .disconnect(). Until then, it is undefined.'.
Making the default value as false in worker.js
