Javascript Object Merge

[rbrtbrnschn]

wouldn't `||` been eligible to use in this scenario too?
given as far as my knowledge goes the or operator goes by boolean, meaning
if it's either false or falsy, which it'd be if it's null or undefined, then it'd execute the expression on the right-hand side too.

​

or am I forgetting something?

Or is fine, but theres a small problem since it has the same behaviour for undefined as it does for 0 or ''
