JS create an array with objects from other array [duplicate]

Question

let array1 = [1,2,3,4,5]
let array2 = [6,7,8,9,10]
let array3 = [ {x: array1, y: array2} ]

How to write correctly loop, so in output I will get 1 array with 5 ojects inside?

//Expected output

[ {x: 1, y: 6}, {x: 2, y: 7}, {x: 3, y: 8}, {x: 4, y: 9}, {x: 5, y: 10}]

Can you maybe suggest the way you would loop through it? The variable array3 may bring some confusion. — Patrice Thimothee

You should loop through all the values of the first array with .map which generates a new array. The function inside of .map takes the value from array1 as value and array2 as array2[index];

let array1 = [1,2,3,4,5]
let array2 = [6,7,8,9,10]
let array3 = array1.map(function (value, index) {
    return {x: value, y: array2[index]}
})
console.log(array3);

I've intentionally used slightly more verbose solution that could be required for easier readability and understanding.
