Answer 1

Recursively flatten an array:

function flatten(array) {
   return !Array.isArray(array) ? array : [].concat.apply([], array.map(flatten));
}
 
var yourFlattenedArray = flatten([[{"_id":"55064111d06b96d974937a6f","title":"Generic Title","shortname":"generic-title","contents":"

);

log(yourFlattenedArray);

function log(data) {
  document.write('

');
}
