Data Manipulation

map

map takes a source array and maps it using keypath argument, producing another array with different data.

zip

zip takes a source array and converts it into a dictionary with numeric indexes:

{[ var myDictionary @zip(myArray) /]}

For example, let's assume myArray contained names of people ["Anna", "Hanna", "Joe"]. Sometimes, it is also important to know index of the item in the source array. zip provides just that:

{[ map @zip(myArray) into index name /]}
  #{{ index }} - {{ name }}
{[/]}

Correctly producing iteration index. Keep in mind that indexes start from 0:

#0 - Anna
#1 - Hanna
#2 - Joe
