Which code correctly accesses the password property of the loginInfo object using dot notation?

• A. loginInfo.getPassword();
• B. loginInfo.password;
• C. loginInfo["password"];
• D. loginInfo.accessPassword();

Answer: (B)

The correct answer is accessing the password property of the loginInfo object using dot notation. In JavaScript, when you want to access a property of an object, you can use dot notation by specifying the object name followed by a period and then the property name directly. In this case, `loginInfo.password` allows you to directly access the value associated with the `password` property of the `loginInfo` object. Dot notation is a straightforward and commonly used method to access properties when you know the property name beforehand and it conforms to standard naming conventions, which is the case here. This direct approach is typically preferred for its readability and simplicity. Other methods to access object properties, such as using the `getPassword()` or `accessPassword()` methods, may not apply here because they imply the existence of functions rather than directly retrieving a property value. While accessing a property using bracket notation is also valid, it does not utilize dot notation and is usually employed in scenarios where the property name is dynamic or not a standard identifier.
