Class: Nocode::Steps::Map

Inherits:
Nocode::Step show all
Defined in:
lib/nocode/steps/map.rb

Overview

Iterate over a register. Each iteration will store the current element and index in special registers called: _element and _index. You can prefix these registers by setting the element_register_prefix option.

The main difference between this and ‘each’ is that this will collect the iterator element register and set the register to this new collection.
