Get the existing intersections between multiple object arrays - arrays

Question

I have a couple of arrays which have some same ids. What I want to achieve is get the intersections between the arrays in plain javascript, no libraries. If there is a match of Ids and arraypicklist values are not equal between 2 or more arrays I should get an array with the matching Ids.
Below is my example which I tried but this ends up with no ids where I expect at least 1 match. In this case Id:123 as in the first and second array there is a match. So I would expect
intersection = [{"Id":"123","arrayPicklist":"Categorie__c"},{"Id":"123","arrayPicklist":"Regio__c"}];
fiddle:https://jsfiddle.net/ozckc0tw/4/
var buckets = [[{"Id":"123","arrayPicklist":"Categorie__c"}],
[{"Id":"123","arrayPicklist":"Regio__c"}],
[{"Id":"124","arrayPicklist":"Categorie__c"}],
[{"Id":"123","arrayPicklist":"Regio__c"},{"Id":"125","arrayPicklist":"Regio__c"},{"Id":"123","arrayPicklist":
"Regio__c"},{"Id":"126","arrayPicklist":"Regio__c"}]]
function IntersectionByKey(key) {
var i,
j,
k,
ret = [],
item,
args = [].slice.call(arguments, 1);
args.sort(function(a, b) {return a.length - b.length});
i:for(i=0; i<args[0].length; i++) {
item = [Object.assign(args[0][i], {})];
j:for(j=1; j<args.length; j++) {
for(k=0; k<args[j].length; k++) {
if(key in args[0][i] && args[0][i][key] == args[j][k][key]){
item.push(Object.assign(args[j][k], {}));
continue j;
}
}
continue i;
}
ret.push(item);
}
return ret;
}
var key = 'Id';
var intersection = IntersectionByKey.apply(null, [key].concat(buckets));
console.log('intersection '+JSON.stringify(intersection))

Done,Sorry, but I did not looked out your code, I tried my logic with your requirements, You can use it.
my logic
var buckets = [
[{
"Id": "123",
"arrayPicklist": "Categorie__c"
}],
[{
"Id": "123",
"arrayPicklist": "Regio__c"
}],
[{
"Id": "124",
"arrayPicklist": "Categorie__c"
}],
[{
"Id": "123",
"arrayPicklist": "Regio__c"
}, {
"Id": "125",
"arrayPicklist": "Regio__c"
}, {
"Id": "123",
"arrayPicklist": "Regio__c"
}, {
"Id": "126",
"arrayPicklist": "Regio__c"
}]
],
intersection = [{
"Id": "123",
"arrayPicklist": "Categorie__c"
}, {
"Id": "123",
"arrayPicklist": "Regio__c"
}];
var resArray = [];
for (var j = 0; j < intersection.length; j++) {
for (var i = 0; i < buckets.length; i++) {
for (var k = 0; k < buckets[i].length; k++) {
if (buckets[i][k].Id == intersection[j].Id && buckets[i][k].arrayPicklist == intersection[j].arrayPicklist) {
resArray.push(buckets[i][k]);
}
}
}
}
console.log(resArray);
