Create new object from array

Question

I'm trying to create new object with different properties name from Array.

Array is:

profiles: Array(1)
   0:
    column:
        name: "profileName"
        title: "Profile name"
    status: "Active"

I want to create new function that return object with two properties:

id: 'profileName', profileStatus: 'Active'

The function that I have create is returning only one property as undefined undefined=undefined.

function getProfile(profiles) {
    if (!profiles.length) return undefined;

    return profiles.reduce((obj, profile) => {
        console.log('profiles', profile);
        return ({
          ...obj,
          id: profile.column.name,
          profileStatus: profile.status,
        });
      }, {});
}

The function getProfile is taking as input array 'profiles' from outside,

You wrote "profiles" instead of "profile" in the reduce method. — darklightcode

your item is called profile and you are accessing the array "profiles" — Jacob

I've just tested here and this seems to be working actually

const getProfile1 = (p) => p.reduce((obj, profile) =>({
    ...obj,
    id: profile.column.name,
    profileStatus: profile.status,
}), {});

You can use map as an alternative.

var profiles = [{"column":{"name": "profileName3","title": "3Profile name"},"status": "Active"},{"column":{"name": "profileName","title": "Profile name"},"status": "Active"}];

function getProfile(profiles) {
    if (!profiles.length) return undefined;
    return profiles.map(function(profile,v){
      return {id:profile.column.name,profileStatus: profile.status};
   });

}

console.log(getProfile(profiles));

Whenever I use reduce in this way, I usually index the final object by some sort of an id. As noted in another answer, you could use map in this situation as well. If you really want your final data structure to be an object, however, you could do something like this:

/**
 * returns object indexed by profile id
 */
const formatProfiles = (profiles) => {
  return profiles.reduce((obj, profile) => {
    return {
      ...obj,
      [profile.id]: {
        id: profile.column.name,
        profileStatus: profile.status,
      }
    };
  }, {});
};

const profiles = [
  {
    id: 0,
    status: 'active',
    column: {
      name: "profile_name_1",
      title: "profile_title_1",
    },
  },
  {
    id: 1,
    status: 'inactive',
    column: {
      name: "profile_name_2",
      title: "profile_title_2",
    }
  }
];

const result = formatProfiles(profiles);

/**
 * Result would look like this:
 */
// {
//   '0': { id: 'profile_name_1', profileStatus: 'active' },
//   '1': { id: 'profile_name_2', profileStatus: 'inactive' }
// }
