How to create directory nested JSON object to store value?

November 14, 2022

How to create directory like structure in JSON that on insertion value is stored inside last JSON object?

example of output :

 let obj = {
     value : 5,
     next : {
       value : 10,
       next : {
          value : 15,
          next : {
             value : 20,
             next : null
                 }
              }
            }
          }

Now, if we have to insert 25 then it must be stored in the last next node which is after value 20.

>Solution :

If obj has only one value in each level,then below is a reference for you

let obj = {
     value : 5,
     next : {
       value : 10,
       next : {
          value : 15,
          next : {
             value : 20,
             next : null
                 }
              }
            }
          } 

const insert = (value,data) =>{
  let next = data.next
  let prev = null
  while(next!=null){
    prev = next
    next = next.next
  }
  prev.next = {'value':value,next:null}
  return data
}

console.log(insert(22,obj))
