How transform string to recursive object?

Question

I am passing a dot separated string into function

console.log( namespace('a.b.c.d.e'))

and expect get next result

//result => "{"a":{"b":{"c":{"d":{"e":{}}}}}}"

my try (I don't know how to do it recursively)

const namespace = (string)=> {
  return string.split('.').reduce((acc,el)=>{
    acc[el] = {}
  },{})
}

I would probably use somethng like reduceRight to build the object from the inside-out: `...reduceRight((acc, prop) => ({[prop]: acc}),{})` — Nick Parsons, Mar 18 '21 at 09:56

How about the below iteration approach :-

function namespace(input){
let result = {};
let temp = result;
const inputArr = input.split(".");
inputArr.forEach((ele)=>{
  temp[ele] = {};
  temp = temp[ele];
})
return result;
}

console.log( namespace('a.b.c.d.e'))

const input = "a.b.c.d.e"

const output = input.split('.').reverse().reduce((acc,el)=>{
  return {[el]: acc}
},{})
  
console.log(output)
