Even in Javascript, the ?? operator checks explicitly for null or undefined. So it added undefined, but not 0 or false. But adding undefined sounds like a good addition for this operator.

But I love coding at work?!
The problem is that every living entity in a 10 kilometer radius around me, seems to be hellbent on getting me to do anything but coding. Refining work estimates, fixing badge access rights, fixing a driver issue, telling people that you cannot do 1000 things at the same time, teaching the new developer how shit (doesn’t) works, mangling Jenkins into a functional state again, explaning that thing I did a year ago but is only now used (it was very high prio a year ago), writing documentation that noboby ever reads, progress meetings, specialty group meetings, knowledge sharing meetings, company wide meetings, etc.
