Other operators

You’ve seen most of the remaining operators in other examples:

Operator Name Meaning
() Function application Represents a function call
[] List access Refers to the value at the specified index in the list
. Member access Refers to a property of an expression; example: foo.bar selects property bar from expression foo
?. Conditional member access Like ., but the leftmost operand can be null; example: foo?.bar selects property bar from expression foo unless foo is null (in which case the value of foo?.bar is null)
