JavaScript Objects

JavaScript Objects

Objects are used to store data in key-value pairs.

Creating an Object

You can create an object using curly braces {}:

let person = {
    name: "John",
    age: 30,
    city: "New York"
};

Accessing Object Properties

You can access properties using dot notation or bracket notation:

console.log(person.name); // Output: John
console.log(person["age"]); // Output: 30

Adding or Modifying Properties

You can add or modify properties dynamically:

person.country = "USA";
person.age = 31;
console.log(person); // Updated object
