CBy reducing the number of direct connections and centralizing control logic in one mediator component.
DBy duplicating event handling code in each component.
Step-by-Step Solution
Solution:

  1. Step 1: Identify challenges in complex UI

    Many components communicating directly create a tangled web of dependencies.

  2. Step 2: Role of Mediator pattern

    Mediator centralizes control, reducing direct links and simplifying maintenance.

  3. Final Answer:

    By reducing the number of direct connections and centralizing control logic in one mediator component. -> Option C

  4. Quick Check:

    Mediator reduces connections for scalability [OK]
Quick Trick: Mediator centralizes control to reduce complexity [OK]
Common Mistakes:
MISTAKES
  • Thinking more direct connections improve scalability
  • Duplicating event handling everywhere
  • Assuming no communication is needed
