Final answer:
The terms 'stability' and 'mobility' are not standard in the context of functional programming. Functional programming is known for using functions and immutable data to avoid side effects, which could be related to 'stability'.
More context is needed to accurately address these phases.
Step-by-step explanation:
The two phases in functional programming for stability and mobility are not commonly identified in the academic or professional literature surrounding this programming paradigm. Functional programming is a coding style that emphasizes the use of functions and immutable data.
If there are specific 'stability' and 'mobility' phases being referenced, they may belong to a specific framework or methodology rather than the core concepts of functional programming itself. It's important to have a clear context to provide an accurate answer.
In functional programming, functions are first-class citizens and are used to express general logic that can be applied over various data types without causing side effects, which is where the concept of 'stability' could be tangentially related, as it refers to predictability and lack of state changes.
However, the term 'mobility' is not commonly associated with functional programming. Without additional context, we cannot provide a definitive answer on these phases.
