immutabilitással

Immutabilitással is a concept that refers to the inability of an object or data structure to be changed after it has been created. Once an immutable object is initialized with a certain value or state, that value or state remains constant throughout its lifetime. Any operation that appears to modify an immutable object actually results in the creation of a new object with the desired changes, while the original object remains untouched.

This principle has significant implications in software development. Immutability helps in preventing unintended side effects and makes code easier to reason about, as developers can be confident that the state of an immutable object will not change unexpectedly. This predictability is particularly valuable in concurrent programming environments where multiple threads might access the same data, as immutability eliminates the need for complex locking mechanisms to protect against race conditions.

Furthermore, immutable data structures can be more efficient in certain scenarios. Because their state is guaranteed not to change, they can be shared freely among different parts of a program without the risk of corruption. This sharing can reduce memory consumption and improve performance. Many modern programming languages and libraries are embracing immutability, offering built-in support for immutable data types or encouraging their use through design patterns. The adoption of immutability is often seen as a key practice for building robust and scalable software systems.
