I have a sample object like this:

const test1 = {
  a: {
    b: {
      c: 2
    }
  }
}

When I pass a parameter like: 'a', 'a.b' or 'a.b.c'. How can access the right level of the object in an effective way?

I tried to loop through it but couldn't figure out a method to do it properly.

Any ideas? Thanks,

const test1 = {
  a: {
    b: {
      c: 2
    }
  }
}

const item1 = 'a.b'
const item2 = 'a.b.c'

console.log(test1[item1]) // should be { c: 2 }
console.log(test1[item2]) // should be 2

Thanks @Nit for your reference. – Dale Nguyen Nov 11 '19 at 16:27
Simply, what you want is if you have 'a.b.c' you need to show {c: 2}. Am I correct? – Dushan Ranasinghage Nov 12 '19 at 13:49
It's true. Do you have a better method than the one from Nit? – Dale Nguyen Nov 12 '19 at 17:10
I have a solution for your problem. But this question is already closed. how can I give you the code? – Dushan Ranasinghage Nov 13 '19 at 04:34
@DushanRandika you can contribute the duplication above. I will able to see it. – Dale Nguyen Nov 13 '19 at 15:11
