?? is intuitive if you (truly) understand ||
Yea, I don't know why people want to learn things - it's easier to just know them! /s
Have you tried divining syntax from reading the entrails of a sacrificed goat?
It works on my machine
What? The previous comment said it's "downright impossible to learn" which is nonsense.
|| means "Evaluate and use the left operand, unless it's falsy, in which case evaluate and use the right operand instead"
?? means "Evaluate and use the left operand, unless it's nullish, in which case evaluate and use the right operand instead"
They're the same thing except for which values fall through to the second operand
Yea, I'm well aware.
But you had to learn that somewhere... nothing is intuitive for a novice.
