Use an index found in a array as a selector to another array

[wolicodes]

Considering this JSON

{
  "titles": ["foo", "bar"]
  "values": ["fooValue", "barValue"]
}

How would you path to barValue using the index of "bar" in the titles array?

I'd have to know more about the use case, but could you use something like this?

$.values[?(@ == @parent.titles[1]+"Value")]
