What is the event loop in JavaScript?

Description : The event loop is responsible for managing the execution of code, event handling, and asynchronous operations.

Answer :

The event loop is a core mechanism of JavaScript that handles asynchronous operations. It continuously checks the call stack to see if there is any function that needs to run. If the call stack is empty, the event loop will look at the task queue to see if there are any pending tasks (like callbacks from asynchronous operations) that need to be executed. This allows JavaScript to perform non-blocking operations despite being single-threaded. 

console.log('Start');

setTimeout(() => {
  console.log('Timeout');
}, 0);

console.log('End');

// Output:
// Start
// End
// Timeout
