indexOf() when array-elements are objects (javascript)

Question

For instance, a variable named arrayElements of type array contains:
[{id:1, value:5},{id:2, value:6},{id:3, value:7},{id:4, value:8}].

How do I get the position of the array element with id === 3(3rd element) in the arrayElements variable besides using loop?

thanks.

Answer 1

const arrayElements = [
  { id: 1, value: 5 },
  { id: 2, value: 6 },
  { id: 3, value: 7 },
  { id: 4, value: 8 }
]

console.log(arrayElements.findIndex((item) => item.id === 3))
