Create and manage objects using the literal syntax.
Object literals are the most common and straightforward way to create objects in JavaScript. An object is a collection of key-value pairs, where keys are strings (or symbols) and values can be any data type, including other objects or functions. The literal syntax uses curly braces `{}` to define an object. Inside the braces, you define properties as `key: value` pairs, separated by commas. This syntax is not just for creating static objects; it's also been enhanced in ES6. For example, if you have a variable with the same name as the property key you want to create, you can use the shorthand property syntax. ES6 also introduced computed property names, allowing you to use an expression in square brackets `[]` as a property key, which is useful for creating dynamic objects. You can access an object's properties using either dot notation (`object.property`) or bracket notation (`object['property']`). Dot notation is cleaner and more common, but bracket notation is necessary when the property name is a variable or contains special characters. Understanding how to create, access, update, and delete properties is a fundamental skill for any JavaScript developer, as objects are used to model everything from simple data records to complex application states.
