Why is it important to create separate instances of classes or objects during development?

Creating separate instances of classes or objects is important for:

• Ensuring the independence of each object's state. Using a single instance for different tasks can lead to conflicting states.
• Supporting object-oriented programming principles such as encapsulation and abstraction.
• Avoiding side effects during parallel execution of code.
• Allowing different configurations or data in each instance.

For example, if you have a class User, you should create a separate object for each user to store that user's unique data.
