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

The following should work - uses a few ES6 helpers, but the key is Array#reduce which is in ES5.

const result = arrayOfObjects.reduce((acc, obj) => {
    for (let key in obj) {
        if (key in acc) {
            acc[key].push(obj[key]);
        }
        else {
            acc[key] = [obj[key]];
        }
    }
    return acc;
}, {});
