function to convert given string to object
input: 
a.b.c = "test"

output: 
{ a : { b : { c : "test" } } } 

Solution: 


function getObj(key, value){
 const rtnObj = {};
  
 const subKeys = key.split(".");

 const getNestedKey = (obj, nextKey, value) => {
  obj[nextKey] = value;
 }

 if(subKeys.length){
  let currObj = rtnObj;
  for(let i =0; i < subKeys.length; i++){ // 0 , 1 , 2
    
   if(i + 1 === subKeys.length){  
    console.log("last key", subKeys[i]);
    currObj[subKeys[i]] = value;
   }
   else {
    currObj[subKeys[i]] = {};
   }
   currObj = currObj[subKeys[i]];
  }

 }

 return rtnObj;
}

console.log(getObj("a.b.c", "test"));
