$., Meta Values (json)

State information for iteration blocks

Description

Meta Values, $., provides state information for blocks like foreach, formap, while and lambdas.

Meta Values are a specific to the block, so you will need to refer to each iteration structure's documentation to check what information is exposed via $.

Examples

» %[Monday..Friday] -> foreach day { out "$.i: $day" }
1: Monday
2: Tuesday
3: Wednesday
4: Thursday
5: Friday
