Part 7: Objects in JavaScript What Are Objects? Objects in JavaScript are collections of key-value pairs. They're used to represent entities with properties and behaviors. Here's how you create an object: let person = { name : " Alice " , age : 30 , isStudent : false }; 1. Curly braces {} define an object. 2. Each property is a key-value pair separated by a colon. Accessing Object Properties You can access object properties using dot notation or bracket notation: console . log (person . name) ; // Output: "Alice" console . log (person[ " age " ]) ; // Output: 30 Modifying Object Properties To change the value of an object property, simply assign a new value to it: person . age = 31 ; console . log (person . age) ; // Output: 31 Adding and Deleting Properties You can add new properties to an object or delete existing ones as needed: person . country = " USA " ; // Adding a new property delete person . isStudent ; /
