How to get a property from a string by name?

Question

JavaScript

const elements = {
    attributes: {
        text: "Привет"
    }
}

function getKey(key){
    return elements.attributes.key;
}
let value = getKey("text"); // elements.attributes.text - "Привет"

Can this be done without using eval()? If possible, how?

Answer 1

function getKey(key){
    return elements.attributes[key];   // <- так
}
