?? Null Coalescing Operator --> What does coalescing mean?

Question

I\'m tempted to lie and say that English is my second language, but the truth is that I just have no idea what \'Coalescing\' means. I know what ?? \'does\' in

Answer 1

Coalescing is when you have more than one item and then you end up with exactly one—either by joining the items together or by choosing a single item from the group. In the case of the ?? operator, you're choosing the first non-null value of the pair of values.
