Node.js - Timers and Scheduling

Why does this code never print 'Done'?

function loop() {
  process.nextTick(loop);
}
loop();
console.log('Done');

Aconsole.log is inside the loop function and never called

Bprocess.nextTick keeps scheduling loop before console.log runs

Cprocess.nextTick is asynchronous and delayed

Dloop function has syntax error

Step-by-Step Solution

Solution:

Step 1: Understand process.nextTick scheduling
It schedules loop to run before any I/O or timers.
Step 2: Analyze event loop blocking
loop keeps rescheduling itself, blocking the event loop from reaching console.log.
Final Answer:
process.nextTick keeps scheduling loop before console.log runs -> Option B
Quick Check:
nextTick recursion blocks event loop [OK]

Quick Trick: nextTick recursion blocks other code from running [OK]
