Using variables with nested Javascript object

Question

Suppose I have this:

var a = { A : { AA : 1 }, B : 2 };

Is there a way for me to create a variable that could allow me to reference either

Answer 1

With lodash _.get function, you can access nested properties with dot syntax.

Node server-side example:

const _ = require('lodash'); 

let item = { a: {b:'AA'}};

 _.get(item, 'a.b');
