Review: Using JavaScript Objects
Objects are an essential data type of JavaScript, and learning how to use them is necessary to develop applications. We will start with a quick review of objects from the first course. Try the examples in this article to review creating and manipulating objects, accessing objects using dot [.] notation and bracket notation, and setting and getting object members. You can use the JavaScript Console on your browser DevTools to complete the examples.
