Object-oriented programming · interview question
How does making a class immutable help reduce mutation bugs in an e-commerce application?
Multiple choiceMediumchapter-3-curatedpremiumoopimmutability-basics
Answer and explanation
Correct answer
B. Immutable objects do not change state, reducing unintended side effects.
Why
Immutable objects cannot change state after creation, which prevents unintended side effects from occurring when objects are shared across different parts of the application. This reduces mutation-related bugs, especially in concurrent environments.
