arrays - Search through a JavaScript object and its nested properties looking for something in underscore -

i looking use .where or .find through array of objects like:

looking user inputs might match.

so imaging, have expanded object have array of them. can see here, there relationship between object (user) , profile (the expanded node). if enter in (into search box) "ca", should matching elements because see here: user.profile.data.country === 'ca' evaluates true.

now if enter in "kyle", again should object because middle_name kyle.

the question is, how use where or find search array of objects, going deep nesting goes search value matches?

an example of how deep nesting can go:

- user   - profile   - contact_info   - id_verification   - investments (array)     - offering       - company 

if type in "shoppers" , shoppers company return object. ideas?

you can use recursion find property given value; added path attribute indicate nested object found

var data = {     user: {         profile: {},         contact_info: {},         id_verification: {             name: 'any'         },         investments: [{             offering: "an offer",             company: "acme"         }, {             offering: "an offer",             company: "shopping"         }]     } }   function search(obj, tomatch, path) {     path = path ? path : '';     if ((!_.isobject(obj) && !_.isarray(obj)) || _.isempty(obj)) return false;     var = _.indexof(_.values(obj), tomatch)     if (i > -1) {         var f = {}         f[_.keys(obj)[i]] = _.values(obj)[i];         f.path = path;         return f;     } else {         path = path + '|any'         (var v in obj) {             var = path.split('|')             a.pop();             a.push(v);             path = a.join('|');             var found = search(obj[v], tomatch, path);             if (found) {                 return found;             }         }     } } search(data, 'shopping')
