What are the timing features of Node.js?

The Timers module in Node.js contains functions that execute code after a set period of time.

• setTimeout/clearTimeout – can be used to schedule code execution after a designated amount of milliseconds
• setInterval/clearInterval – can be used to execute a block of code multiple times
• 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(){
  console.log('Processed in next iteration');
}
process.nextTick(cb);
console.log('Processed in the first iteration');

Output:

Processed in the first iteration
Processed in next iteration
