How do you get value?

Question

I wanna get a value in object.

const object = {
      foo: {
        hoge: []
      }
    }
    
console.log(object["foo"]); //-> {hoge:[]}
console.log(object["foo"]["hoge"]); //-> []

? is String.

Is there a person who can solve it?

I have a answer. Using eval

console.log(eval("object.foo.hoge]")); //-> []

but, I do not want to use eval

Thanks.

I'm not sure what you're asking for? – Magd Kudama Apr 30 '18 at 18:03 — Magd Kudama, Apr 30 '18 at 18:03
I want to get a value in the form `obj[?]` Without eval. – Junya Kono Apr 30 '18 at 18:14 — Junya Kono, Apr 30 '18 at 18:14

object["foo"]["hoge"] will do what you want. Note that because the keys are valid identifiers, you can use the shorthand attribute access syntax: object.foo.hoge.

I would like to conclude in []. Therefore, you can not write like `[foo] [hoge]` or `foo.hoge` . – Junya Kono Apr 30 '18 at 18:09
@JunyaKono That's not possible. (Not without changing `object`, anyway.) – cdhowie Apr 30 '18 at 18:16
@JunyaKono You might be interested in [lodash](https://lodash.com/docs/), which has a helper for this: `_.get(object, 'foo.hoge')`. – cdhowie Apr 30 '18 at 18:20
that's cool! Thanks! – Junya Kono Apr 30 '18 at 18:22
