Objects are one of the most important data structures in JavaScript. They are used to store data in a way that is more complex than arrays.
In JavaScript, an object is defined using the {} curly braces. The properties of an object are defined using the : colon. For example, the following code defines an object with two properties:
Code snippet
const person = {
name: "John Smith",
age: 30,
};

The person object can be accessed using its properties. The properties of an object can be accessed using the dot notation. For example, the following code will print the value of the name property of the person object:
Code snippet
console.log(person.name); // "John Smith"

Objects can be accessed using a variety of methods, such as hasOwnProperty(), in, and keys(). These methods allow you to check if an object has a property, iterate over the properties of an object, and get the list of properties of an object.
Objects are a powerful tool that can be used to store and manipulate data in JavaScript. They are used in a wide variety of JavaScript applications, such as web development, game development, and data science.
