Playing with Node.js Event Loop

setImmediate/clearImmediate - will execute code at the end of the current event loop cycle
process.nextTick - used to schedule a callback function to be invoked in the next iteration of the Event Loop

function cb(msg){
setImmediate(cb, 'setImmediate');
process.nextTick(cb, 'process.nextTick: 1');
process.nextTick(cb, 'process.nextTick: 2');
process.nextTick(cb, 'process.nextTick: 3');
console.log('Processed in the first iteration');
process.nextTick(cb, 'process.nextTick: 4');
process.nextTick(cb, 'process.nextTick: 5');


Processed in the first iteration
process.nextTick: 1
process.nextTick: 2
process.nextTick: 3
process.nextTick: 4
process.nextTick: 5
