JavaScript
#1

Tell us what’s happening:

i tried solving this problem with recursion however i dont know if what i am doing is the correct way or if i am missing something it seems like i am close.

Your code so far


function steamrollArray(arr) {
let obj = []
let element

    if(!Array.isArray(arr)){
      element = arr
        
        return element
     }
    else  if(arr == '[object Object]'){
    return JSON.stringify('{}')


    }

   else if(Array.isArray(arr) ){
      
      arr.map(item=>{
      
      obj.push(steamrollArray(item))

    })


}
console.log(obj)


}

steamrollArray([1, {}, [3, [{},[4]]]]);

Generally it’s possible to do this with recursion, yes. As with recursion what need to be considered is an appropriate base case, and way recursive calls are made otherwise to get closer to the base case.

Notice that right now function not in every case is returning something, hence the undefined that can be observed in result.
