I'm trying to create an object with multiple key-pair values inside.

The values I'm using will be be ing from an API and I'm trying to convert the response into a single object.

My code:

json_users.forEach(function (user){
    var user_name = user.name;
    var object_user = {user_name: null};

    temp_collection.push(object_user);
})

The kind of result I want

{"key_1":val_1, "key_2", val_2}

The result I get

[{
    0: {
        .....
    }, 
    1: {
        .....
    }
}]

• 2 It's not clear what you are starting with. Keys in Objects are unique, so looping over an array and setting user_name on the same object will only set one user_name. It might help if you can give an example of the json_users. If you are trying to use user_name as the key, put it in brackets {[user_name]: values} – Mark Commented Jan 6, 2019 at 2:04
• Could you please add an example of this code you’re looping through, as we don’t know what you started with. – Jack Bashford Commented Jan 6, 2019 at 2:07
• I simply want to be able to create an object that will contain values without an index when pushing to it. Like `{"k1":v1, "k2":v2} instead if {[ [0] {"k1":v1} [1] {"k2":v2} ]} – Rick Commented Jan 6, 2019 at 2:08

var resultObject = {};
json_users.forEach(function (user, index){
    var user_name = user.name;
    var object_user = {user_name: null};

    resultObject["key" + (index + 1)] = object_user;
});

resultObject will be what you need. Instead of "key" + (index + 1) you can use user.id or something like that. This way you will have a dictionary of users, where keys will be IDs and values will be user objects

You shouldn’t use .push() - this is creating the array. Try this instead:

var temp_collection = {};
json_users.forEach((user, index) => temp_collection[`key_${index}`] = user.name);

This iterates through the array json_user and adds a new property to the temp_collection object with the name property of each object in the array.

The above does use ES6 arrows and template literals though, so here’s a more widely accepted version:

json_users.forEach(function(user, index) {
    temp_collection["key_" + index] = user.name;
})
