ABecause it determines the order in which callbacks execute
BBecause it controls the memory allocation of the program
CBecause it decides the syntax of the code
DBecause it manages the file system permissions
Step-by-Step Solution
Solution:

  1. Step 1: Understand the event loop role

    The event loop manages how Node.js handles asynchronous callbacks in order.

  2. Step 2: Connect timing to callback execution

    The timing affects when callbacks are placed in the event loop queue and executed.

  3. Final Answer:

    Because it determines the order in which callbacks execute -> Option A

  4. Quick Check:

    Timing importance = Order of callback execution [OK]
Quick Trick: Timing controls callback order in Node.js event loop [OK]
Common Mistakes:
  • Confusing timing with memory management
  • Thinking timing affects syntax
