Constructing an array of object with two arrays [duplicate]

Question

Is there a nice way of transforming a flat javascript array into an array of objects?

An example would be to transform this array.

I'm stuck in trying to merge the two arrays and create an object with the values.

const dataSet = [
  {
    last_updated: 1662040601,
    x: [
      1660953600, 1661040000, 1661126400, 1661212800, 1661299200, 1661385600,
      1661472000, 1661558400, 1661644800, 1661731200, 1661817600, 1661904000,
    ],
    y: [
      0.07, 0.062, 0.06, 0.0725, 0.075, 0.089, 0.0799, 0.1167, 0.089, 0.08,
      0.077, 0.0639,
    ],
  },
];

Into this:

const array = [
  { data: 1660953600, value: 0.07 },
  { data: 1661040000, value: 0.062 },
  { data: 1661126400, value: 0.06 },
  { data: 1661212800, value: 0.0725 },
];

My attempt:

const arri = dataSet.map((data) => ({
  data: data.x.map((data) => data),
  value: data.y,
}));

Share your attempt pls :) A minimal reproducible example always helps you get answers — Can O'Spam feels disassociated

I hope it will help you..

const array = dataSet[0].x.map((x, i) => ({ data: x, value: dataSet[0].y[i] }));

What do you think about it ?

// try this const result = [] dataSet.forEach(({x, y}) => { x.forEach((data, index) => result.push({data, value: y[index]})) })
