Yes, that's exactly what object literal means. A definition of a javascript object which may contain comma separated definition of properties, functions, ...

Object literals are formed using the following syntax rules:

• A colon separates property name from value.
• A comma separates each name/value pair from the next.
• There should be no comma after the last name/value pair. Firefox won't object if you add it, but Internet Explorer will trigger an error: 'Expected identifier, string or number'.

An Object is simply a collection of key/value pairs. And yes, they both hold data. But a database is designed to do much more than hold data. It indexes it, provides optimizations to access, read, define in-depth meta about each field, restrict the values to data types (JS is a loose language, ie, it does not support strict data typing). Simply put, an Object literal is a JS object, described in a literal method. What is a literal string? 'Hello, I am a literal String.'. What is a String Object? var myStringObject = new String('Hello, I am a String Object');. One was created via a 'literal' expression, the other via Object (because in JS, everything is an Object). So I can create an object literal by using the following syntax: javascript var objectLiteral = { myKey1: 'A string value', myKey2: 23, myKey3: true }; That is a object literal. If I want to create that same Object, I can do so with the Object.create() method as well as defining its individual key names and properties, like: javascript var pureObject = Object.create(Object.prototype); pureObject.defineProperties({ 'myKey1': { value: 'A string value' }, 'myKey2': { value: 23 }, 'myKey3': { value: true } }); Literals are usually much less code to create.

I'm not sure what it's called but javascript will essentially turn that sounds() function into a key. Similar to something like this: const type = "cat"; const myObject = { type, // so you don't have to do this: // type: type, } So "under the hood" that object will look like: const obj = { type: "cat", sounds: function() { ... } }

Hey Robert, Happy to hear you're loving the course, best of lucks in your journey! An Object literal is when you declare an Object in JavaScript code which is a variable that stores data in key-value pairs, while JSON stands for JavaScript Object Notation and it's a language-agnostic format for storing and transferring data that is based on JavaScript Objects. You'd use Object literals in your code when you need to create an object such as a user profile so you can later read and write its properties, or when you're working with classes which is something you'll see later in the course. JSON is used when you want to store data and transfer it across different platforms and programming languages. One easy way to spot JSON is that you'll see its property names are always inside quotation marks: json { "firstName": "Robert", "lastName": "Paauwe" } While Object literals don't use quotation marks for their property names: javascript let myObject = { firstName: "Robert", lastName: "Paauwe" }; You'll often see JSON data stored as a separate file from JavaScript (.json) while Object literals appear right in JS code.
