immutabeli

Immutabeli is a term that refers to something that cannot be changed after it has been created. In the context of computer science and programming, immutability is a core concept applied to data structures and objects. Once an immutable object is instantiated, its internal state cannot be modified. Any operation that appears to modify an immutable object actually creates a new object with the modified state, leaving the original object untouched.

This principle offers several advantages. Immutability simplifies reasoning about code because you don't have to worry about an object's state changing unexpectedly. It also enhances thread safety in concurrent programming environments, as multiple threads can safely access immutable objects without the risk of data corruption. Furthermore, immutable objects can be efficiently cached and shared.

Examples of immutable data types exist in many programming languages. Strings are often immutable, meaning that operations like concatenation or replacement result in new string objects. Some programming languages have specific immutable collections or data structures, encouraging developers to adopt this paradigm. While it might seem counterintuitive to create new objects for every change, the benefits in terms of predictability, safety, and performance in certain scenarios often outweigh the overhead. The concept is fundamental to functional programming paradigms.
