How to map an array to a property [closed]

Question

I have this array with 3 integers. I want to use these integers and make a new array of objects that populate the y variable. I want to have the x as an id variable. How can I do this?

From:

const arr = [6, 9, 2]

To:

const arrOfObjects = [{x: 1, y: 6}, {x: 2, y: 9}, {x: 3, y: 2}]
