Mutability, When and Why Should It?

Various factors can influence whether mutable or immutable objects are used in programming. Consider the following reasons why programmers may prefer mutability:

• Speed & Efficiency: Some developers may choose mutable objects because they are faster and more efficient. However, on the downside this may result in more time spent fixing bugs in the long run.
• Convenience: Mutable objects often require less code and fewer variables in the short run.
• Necessity: In some cases, using mutation is unavoidable, particularly when dealing with user input or UI modifications.

Overall, mutable objects may be more appropriate in situations where speed is a top priority, such as game development or real-time stock market software. In most cases, the risks of mutation outweigh the benefits. However, for small and simple programs, the risks may not be significant enough to warrant consideration of immutability.
