towerful@programming.dev 10 months agoWhen you want to know the name of the operator for a language.
Like “what does & mean in c++?”.
& isn’t too bad, but some of them can be difficult (like “JavaScript ??”).
And if you don’t know it’s called a reference operator, or a bullish coalescence operator, or whatever… Trying to learn what it does can be downright impossible

Yea, I don’t know why people want to learn things - it’s easier to just know them! /s

Have you tried divining syntaxes from reading the entrails of a sacrificed goat?

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, in well aware.
But you had to learn that somewhere.

For ?? I guess it already has a decent results. I’ll periodically check those kind of cases once the index gets more languages.
