\nreduce<\/h3>\n
Accumulates the values of a Collection into a single V given an initial seed value<\/p>\nSyntax<\/h4>\nreduce<T>(init : T, aggregrator(aggregate: T, item : ?) : T) : T<\/code><\/pre>\nExample<\/h4>\nvar numbers = {1,2,3,4,5,6,8}\nvar sumOfNumbers = numbers.reduce(0, \\ ___aggr, ___number -> ___aggr + ___number)\nprint(sumOfNumbers)<\/code><\/pre>\nOutput<\/h5>\n29<\/code><\/pre>\n
\nunion<\/h3>\n
Returns a new Set that is the union of the two Collections<\/p>\nSyntax<\/h4>\nunion(that : Collection<T>) : Set<T><\/code><\/pre>\nExample<\/h4>\nvar items1 = {1,2,3,4,5,6}\nvar items2 = {4,5,6,7,8,9}\nprint(items1.union(items2))<\/code><\/pre>\nOutput<\/h5>\n[1, 2, 3, 4, 5, 6, 7, 8, 9]<\/code><\/pre>\n
\ndisjunction<\/h3>\n
Returns a new Set that is the set disjunction of this collection and the other collection<\/p>\nSyntax<\/h4>\ndisjunction(that : Collection<T>) : Set<T><\/code><\/pre>\nExample<\/h4>\nvar items1 = {1,2,3,4,5,6}\nvar items2 = {4,5,6,7,8,9}\nprint(items1.disjunction(items2))<\/code><\/pre>\nOutput<\/h5>\n[1, 2, 3, 7, 8, 9]<\/code><\/pre>\n
\njoin<\/h3>\n
