imutável

Imutável is a Portuguese word that translates to "immutable" in English. It describes something that cannot be changed or altered. This concept is fundamental in various fields, including programming, philosophy, and mathematics.

In programming, an immutable object is one whose state cannot be modified after it has been created. Once an immutable object is initialized, its values are fixed. If a modification is required, a new object must be created with the desired changes. This characteristic can enhance program stability, prevent unintended side effects, and simplify concurrency. Examples include string objects in many programming languages.

Philosophically, immutability can refer to the unchanging nature of certain truths or essences. For instance, some philosophical systems posit that certain fundamental aspects of reality or the divine are immutable, existing outside the flux of time and change.

In mathematics, immutable properties are those that remain constant under certain operations or transformations. For example, the sum of two numbers is immutable with respect to the order in which they are added, illustrating the commutative property. The concept of immutable quantities is crucial in understanding mathematical structures and principles.
