Print Fibonacci Series using map or reduce in javascript

I want to print Fibonacci Series using map() or reduce() function in Javascript. I am not able to find anything online for it. I am not quite sure on what my condition would be in the map().

I am basically writing

fib(n){
return new Array(n-1).fill(1).map((_,i) => *This is where I am confused* ) ;
}

It's relatively easy to do this with reduce(), just check for the index and act accordingly:

function fib(n){
  return new Array(n).fill(1).reduce((arr, _ ,i) => {
      arr.push((i <= 1) ? i : arr[i-2] + arr[i-1])
      return arr
  },[]) ;
}
console.log(fib(10))

map() is not an especially good fit because you don't have a natural way to access the earlier states.
