README
This package provides .map() and .reduce() FlowQuery operations.
Could be useful, huh?
Installation
composer require 'psmb/mapreduce:@dev'
Usage
Map
Takes all items in current FlowQuery context, and transforms each value with given Eel operation.
There is a context variable value available, with a value of a current node.
E.g. this would give you an array of identifiers of all child nodes of a given node:
${q(node).children().map('value.identifier')}

Reduce
Takes an Eel Expression as a first argument and initial values as the second. Injects previousValue,
currentValue, index and array context variables.
E.g. imagine you have a collection of Order nodes, where each node has a price property. Now let's try to get a total price for all of the give nodes:
${q(node).children('orders').reduce('previousValue + currentValue.properties.price', 0)
