create an event loop ? code example
Example 1: event loop in javascript
The Event Loop has one simple job — to monitor the Call Stack
and the Callback Queue. If the Call Stack is empty, it will
take the first event from the queue and will push it to the
Call Stack, which effectively runs it. Such an iteration is
called a tick in the Event Loop. Each event is just a function
callback.
Example 2: javascript event loop
function task(message) {
let n = 10000000000;
while (n > 0){
n--;
}
console.log(message);
}
console.log('Start script...');
task('Download a file.');
console.log('Done!');
