Array.filteroncondition(SomeTakeDropOrAllFlag, SomeFunction, SomeParameter)

Apply a function to an array with parameters, and return list that matched/not matched/all Array.suchthat() is Array.filteroncondition with SomeTakeDropOrAllFlag set to 0 (Take when condition is satisfied)

Array.filteroncolumn(SomeCondition, SomeExtractColumns, SomeFilterOnColumn)

SomeExtractColumns are the columns that are extracted, and filters are applied on SomeFilterOnColumn or column 0 1..100.filteroncolumn(">5")

Array.filteronrow(SomeCondition, SomeExtractRows, SomeFilterOnRow)

SomeExtractRows are the rows that are extracted, and filters are applied on SomeFilterOnRow or row 0 [1..100].filteronrow("<5")
