Question 54154 in Javascript Question posted in
A very good W3school tutorial can be found here.

How an array passed in the object 1 per each passed member id – Javascript

I have an array that contains several elements after that I created an object in which I passed this array as a value but it passed all the values as a single string.

var cars = ["Saab", "Volvo", "BMW"];
console.log(cars);
var test = Object.assign({}, cars);
console.log(test);

var anv = {
new1 : test,
id : "1.K"
}
console.log(anv);

The Output we are getting is this
enter image description here

But output we require after passing the array inside object

0:{id:"1.R", new1:"Saab"}

1:{id:"1.R", new1:"Volvo"}

2:{id:"1.R", new1:"BMW"}

I have tried the object assign method but not works for me

    Use the .map function to create an object for each item in the list

    const cars = ["Saab", "Volvo", "BMW"];

const anv = cars.map(
  car => ({
    id: "1.K",
    car: car
  })
)

console.log(anv);

    Instead of using Object.assign at the beginning, you can first create the array of your desired output and then use Object.assign.

    Here is a demo-

    var cars = ["Saab", "Volvo", "BMW"];
var anv = [];

cars.forEach(item => {
  anv.push({
    new1: item,
    id: "1.K"
  })
})

var result = Object.assign({}, anv)
console.log(result)

    Please let me know if I didn’t get your use case.
