Using Lodash `_.get` to access object key using bracket notation

Question

I have the following

const key = 'foo';
const test = { foo: { bar: 23 } };

and I'd like to use lodash get to access the value of test[key].bar.

I want to use the bracket notation on the first indicator...

_.get(test, '[key].bar'); // results in undefined

Surely there's a way...

Answer 1

You can pass an array to define the evaluation path.

This is one pretty clean solution to your problem:

const test = {foo: {bar: 23}}
const key = 'foo'

console.log(_.get(test, [key, 'bar'])) // 23
