enum SourceEnum { value1 = <any>'value1', value2 = <any>'value2' } enum AdditionToSourceEnum { value3 = <any>'value3', value4 = <any>'value4' } // we need this type for TypeScript to resolve the types correctly type TestEnumType = SourceEnum | AdditionToS...

@sorted = sort @list; @sorted = sort { $a cmp $b } @list; sub compare { $a cmp $b } @sorted = sort compare @list; The three examples above do exactly the same thing. If you don't supply any comparator function or block, sort assumes you want the list on its right sorted lexically. This is ...

@sorted = sort { $a <=> $b } @list; Comparing $a and $b with the <=> operator ensures they are compared numerically and not textually as per default.

@sorted = sort { $b <=> $a } @list; @sorted = reverse sort { $a <=> $b } @list; Sorting items in descending order can simply be achieved by swapping $a and $b in the comparator block. However, some people prefer the clarity of a separate reverse even though it is slightly slower.
