Iterating through an array of objects in jQuery and matching attributes

Question

I'm trying to loop and group through this object array using jQuery using my loop value.

I'd like the final object to look like this.

[ {'organization':'ABC Inc', 'address':'123 Front', 'city':'Wilmington','state':'NC','zip':'09900'}, {'organization':'Wonton Inc', 'address':'555 Front', 'city':'Jasper','state':'NC','zip':'09877'}, {'organization':'ABC Inc', 'address':'123 Front', 'city':'Wilmington','state':'NC','zip':'45345'} ]

Post the original object and the loop script you used to console log each attributes. Maybe there is not much missing to group them. — Louys Patrice Bessette

I meant to simplify since the code is very complicated. @LouysPatriceBessette — nivanmorgan

Use a hash table and #reduce() function to extract the data structure required - see demo below:

var object = [{loop:0, key: 'organization', value:'ABC Inc'}, {loop:0,key:'address',value:'123 Front'}, {loop:0, key: 'city',value:'Wilmington'},{loop:0, key:'state',value:'NC'},{loop:0, key:'zip',value:'09900'}, {loop:1,key:'organization',value:'Wonton Inc'},{ loop:1, key:'address',value:'555 Front'}, {loop:1,key:'city',value:'Jasper'},{loop:1, key:'state',value:'NC'},{loop:1, key:'zip',value:'09877'}, {loop:1, key:'organization',value:'ABC Inc'},{loop:1, key:'address',value:'123 Front'},{loop:1, key:'city',value:'Wilmington'},{loop:1, key:'state',value:'NC'},{loop:1, key:'zip',value:'45345'}];

var result = object.reduce(function(hash){
  return function(p,c) {
    if(!hash[c.loop]) {
      hash[c.loop] = {}
      p.push(hash[c.loop]);
    }
    hash[c.loop][c.key] = c.value;
    return p;
  }
}(Object.create(null)), []);

console.log(result);

.as-console-wrapper{top:0;max-height:100%!important;}
