I’m learning swift and I actually just discovered
??today. Am I missing out in other languages?C# and Kotlin both have it
Yes, it's very useful when applied correctly.
I'm always disappointed when I remember, that I can't use such a feature, because I'm stuck using Java.
Maybe you'r using an older version of Java? Works fine for me.
New versions of java have a null coalescing operator?
I didn't know that.
Edit: a short search didn't return any answers, as far as I can see java doesn't have this operator, the closest thing is the ternary if operator.
PHP too
C#
JavaScript and TypeScript too
