What does abstraction in programming primarily focus on?

Abstraction in programming primarily focuses on providing only essential features to users while hiding the complex implementation details. This concept allows developers to interact with an interface or object without needing to understand the intricacies behind it. By emphasizing the necessary elements, abstraction simplifies the interaction between the user and the system, shielding users from the underlying complexity.

It encourages a clearer design by allowing programmers to use functions and objects without needing to know how they are implemented, thereby promoting greater efficiency and reducing the chances for error. In this way, abstraction aids in managing complexity in larger software systems, making them easier to understand and maintain.
