JavaScript Is it possible to have Getter/Setter in an Array?

I've just learnt about Getters/Setters for objects and decided to play with it. However, I tried to put a Getter in an array and failed to do so. Is it not possible or am I just doing something wrong?

const obj = {
  a: 1,
  get b() { return this.a + 1 } 
}

console.log(obj.b) //2

For Array

const arr = [
  1,
  get () { return this[0] + 1 } 
]

console.log(arr[1]) // Doesn't work
