First  choosing a data structure xml json yaml  usually includes only a readability size problem  For example  Json is very compact  but no human being can read it easily  very hard do debug   Xml is very large  but everyone can easily read debug it   Yaml is in between Xml and json   But if you want to work with Javascript heavily and or your software makes a lot of data transfer between browser-server  you should use Json  because it is pure javascript and very compact  But don t try to write it in a string  use libraries to generate the code you needed from an object   Hope this helps

The first code is an example of Javascript code  which is similar  however not JSON  JSON would not have 1  comments and 2  the var keyword  You don t have any comments in your JSON  but you should remove the var and start like this   orders      The      notation means  object in an array  and is not what you need everywhere  It is not an error  but it s too complicated for some purposes  AssociatedDrug should work well as an object    associatedDrug                      name   asprin                    dose                       strength   500 mg                Also  the empty object labs should be filled with something   Other than that  your code is okay  You can either paste it into javascript  or use the JSON parse   method  or any other parsing method  please don t use eval   Update 2 answered   obj problems 0  Diabetes 0  medications 0  medicationsClasses 0  className 0  associatedDrug 0  name   returns  aspirin   It is however better suited for foreaches everywhere

Make sure you follow the language definition for JSON  In your second example  the section    labs                 Is invalid since an object must be composed of zero or more key-value pairs  a     b   where  b  may be any valid value  Some parsers may automatically interpret        to be        null    but this is not a clearly defined case   Also  you are using a nested array of objects      quite a bit  I would only do this if    There is no good  identifier  string for each object in the array  There is some clear reason for having an array over a key-value for that entry

You can try use this function to find any object in nested nested array of arrays of kings   Example  function findTByKeyValue  element  target           var found   true          for var key in target                 if   element hasOwnProperty key     element key      target key                        found   false                  break                                  if found                return element                    if typeof element       object                  return false                    for var index in element                 var result   findTByKeyValue element index  target               if result                     return result                                    findTByKeyValue problems   name   somethingElse   strength   500 mg          gt  result equal to object associatedDrug 2
