Object is given: let obj = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}; Convert the keys of this object in one array, and the values in another

I have a problem with converting object keys and values in two separate arrays.

Please see my code below:

let obj = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5};
let arr1=[];
let arr2=[];
for( key in obj){
  for(let i=0; i<5;i++){
    arr1[i]=key
    arr2[i]=obj[key]
  }
}
 console.log(arr1)
 console.log(arr2)

I have wrong answer: [ 'e', 'e', 'e', 'e', 'e' ] [ 5, 5, 5, 5, 5 ]

Why not use Object.keys and Object.values:

If you wanted to use your code:

let obj = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5};
let arr1=[];
let arr2=[];
for(let key in obj){
  arr1.push(key);
  arr2.push(obj[key]);
}
 console.log(arr1)
 console.log(arr2)
