When working with JSON objects, we typically access elements using dot notation. For example,
var obj = {"key": "value"}; var val = obj.key;var obj = {"key-with-hyphens": "value"};var val = obj['key-with-hyphens'];To retrieve the value, use the following syntax:
let value = obj["key-with-hyphens"];
> let myObj = {"key-with-hyphens": "myValue"};
> myObj["key-with-hyphens"];
< "myValue"
