👉 Immutable is a technical concept in computer science, specifically in functional programming languages. It refers to values or objects that cannot be changed once they have been created.
In other words, an immutable object cannot be modified after creation, and it cannot be reassigned to another value. This property is essential for certain operations such as function composition, where the result of one operation needs to match exactly with another.
For example, a string cannot be changed by adding new characters or removing existing ones without affecting its original
