For example, a function that would be const arrToNestObj = arr => {} and would get [a, b, c, d, e] and return

a: {
  b: {
     c: {
        d: {
           e: {

           }
        }
     }
  }
}

Thanks!

Use Array.reduceRight() to create a nested object:

const arrToNestObj = arr => 
  arr.reduceRight((acc, key) => ({ [key]: acc }), {})

const arr = ['a', 'b', 'c', 'd', 'e']

const result = arrToNestObj(arr)

console.log(result)
