Niemutowalno

Niemutowalno is a term encountered in Polish-language discussions to denote the property of immutability. It is a less common or informal form derived from niemutowalny, the standard adjective meaning immutable, and is sometimes used as a shorthand reference to the concept of immutability (niemutowalność). In most technical contexts, the noun niemutowalność is preferred, but niemutowalno may appear in informal writing or glossaries.

In essence, niemutowalno describes the state where an object’s or data structure’s value cannot be changed after its creation. When a change is required, a new object is produced instead of altering the existing one. This principle contrasts with mutability, where objects can be modified in place.

In computing, immutability is a design choice with practical implications. Immutable data types are common in functional programming and are valued for predictability, thread safety, and easier reasoning about code. Examples include strings in many languages and certain data structures implemented as persistent (versioned) structures. Immutable objects can reduce side effects and help maintain consistent state across concurrent processes, though they may incur overhead from creating new instances.

Applications span programming language design, database transactions, configuration management, and blockchain-related data integrity. Critics point to potential performance costs and memory usage, mitigated by techniques such as structural sharing and copy-on-write strategies.
