If I have an array of 3 integers in C#, [1,2,3], I can transform that array into another with the .Select method like so:
[1,2,3].Select(e => new { Id = e, Name = $"name:{e}")Is there a way to achieve the same result in JavaScript without using a for loop?
To utilize the map function, you can follow this example:
let numbers = [4, 8, 12];
let mappedNumbers = numbers.map(num => ({value: num, square: num * num}));
console.log(mappedNumbers);
The output will be:
[ { value: 4, square: 16 },
{ value: 8, square: 64 },
{ value: 12, square: 144 } ]
If you want to learn more about the map function, check out the documentation here:

A function that can transform elements in an array is called map. This example shows how you can use map to double each element in the array (this works not only for integers but also objects):
const numbers = [2, 5, 10, 20];
const doubledNumbers = numbers.map(num => num * 2);
console.log(doubledNumbers);
// expected result: Array [4, 10, 20, 40]
