I am working on a project; the object has a dynamic key and a dynamic value. I will find which number the keys are holding, and change the number to string value, assuming the object list is too big to check each individually- more than 30 key values

```
const obj =  {
    one: 'jkej',
    two: 123,
    three: 'abc'
  }

```

Required output is

```
const obj =  {
    one: 'jkej',
    two: '123',
    three: 'abc'
  }

```

I want to change the what are the keys holding, and change the number value to string.
