How can you merge objects in array of objects?

Question

I\'m looking for the best solution to merge all objects in one array

const arrayOfObjects = [
 {name: \'Fred\', surname: \'Shultz\'}, {name: \'Anne\', surnam         


        

Answer 1

You can use lodash's mergeWith like so:

const result = _.mergeWith({}, ...arrayOfObjects, (value, objValue) =>
    (value || []).concat(objValue)
);

Example:

const arrayOfObjects = [
    {name: 'Fred', surname: 'Shultz'}, {name: 'Anne', surname: 'Example'}
];

const result = _.mergeWith({}, ...arrayOfObjects, (value, objValue) =>
    (value || []).concat(objValue)
);

console.log(result);
