guys,

I want to learn a more complex usage of methods, array's and objects. For exemple i have this dummy array:

const userArr = [
  {
    name: 'john doe',
    sales: 9500,
    projects: 2,
  },
  {
    name: 'john doe',
    sales: 5500,
    projects: 1,
  },
  {
    name: 'max payne',
    sales: 7500,
    projects: 2,
  },
  {
    name: 'max payne',
    sales: 25000,
    projects: 2,
  },
];

And i want to sum up all the sales and projects for each user and add that in to a new array. The result should look like this:

const uniqueUserValues = [
  {
    name: 'john doe',
    sales: 15000,
    projects: 3,
  },
  {
    name: 'max payne',
    sales: 32500,
    projects: 4,
  },
];

I have some attemps with reduce method but no success. I can't get the logic of it. I would greatly appreciate a solution.

Thanks!
