How to associate array value to references

Question

i have 2 arrays. One with users and other with user's manager

var user=[a,b,c,d,e];
var manager=[x,y,z]

how to associate users to respective managers if the manager is same for users

manager  user
x        a,b
y         c
z        d,e

i'm looking to achieve in javascipt.

So you *have* a mapping in-hand, and you want to know the best way to represent that mapping in JavaScript? — apsillers, Feb 05 '18 at 19:01
do u mean like manager_user = [{"mgr": "x", "users": ["a", "b", "e"]}]; — Daniel B, Feb 05 '18 at 19:04
It would probably be easier if you described how you wanted to use this thing. — Matt Burland, Feb 05 '18 at 19:11

That's easy you can do it by

var manager_user = [
    {
        "mgr": "x",
        "users": [
            "a",
            "b",
            "e"
        ]
    }
];

And it's a validated json!

Update: Based on yr comment you can use functions and do object literals:

var Manager_User = function(mgr, usrs) {

    return {
        manager: mgr,
        usrs: usrs,
        addUser: function(mgr, usr) {
            usrs.push(usr);
        },
        removeUser: function(index) {
            usrs.splice(index, 1);
        }
    }
}

var mgrUser = new Manager_User("x", ["a", "b", "c"]);

I've uploaded some of my js examples on github, you can have a look, especially calc.js

Be careful with downvotes, we are not sure if this is what OP really wants. – DontVoteMeDown Feb 05 '18 at 19:07
@DontVoteMeDown don't understand what u mean but it's a validated json – Daniel B Feb 05 '18 at 19:11
There is nothing wrong with your code tho, but your answer may be wrong, if OP update with a new information that will invalidate it. – DontVoteMeDown Feb 05 '18 at 19:12
how can i construct this? – Karthik Subramani Feb 05 '18 at 19:21

@DanielB What do you mean by "*it's a validated json*"? I don't see any JSON in your answer. – Bergi Feb 05 '18 at 21:50

you can keep key value pair. key as manager.value as a array of {a,b}.

var obj = {
key1: value1,
key2: value2
};

obj["key3"] = "value3";

obj["x"] = {"a","b"};

How can I add a key/value pair to a JavaScript object?
