Most JS array group taking the maximum, packets

Summary of the code, using the JS data packets, the array of taking the maximum packet array;

 var combineTemplate = the JSON.parse (data.combineTemplate); 

                // instrument according to packet type ID 
                var TEMP = {}, 
                    dest = []; 

                for ( var I = 0; I <combineTemplate.length; I ++ ) {
                     var ELE = combineTemplate [I];
                     IF {(TEMP [ele.typeId]!) // absent to give a new element is added 
                        dest.push ({ 
                            ID: ele.typeId, 
                            Data: [ELE] 
                        }); 
                        TEMP [ele.typeId] = ele
                    } The else { // the presence of sub-elements give additional data 
                        for ( var J = 0; J <dest.length; J ++ ) {
                             var dt = dest [J];
                             IF (dt.id == ele.typeId) { 
                                dt. data.push (ELE); 
                                BREAK ; 
                            }

                    } 
                } 

                // get the object data up to a 
                var arrayMax = []; // maximum array 
                for ( var I = 0; I <dest.length; I ++) {
                    var element = dest[i];

                        arrayMax=element.data;
                    }
                }
