In my code, I am utilizing the Node Events module to execute a function asynchronously.
var events = require('events');
var eventEmitter = new events.EventEmitter();
eventEmitter.on('myEvent', f2);
function f1(x, y) {
console.log('received', x, y)
eventEmitter.emit('myEvent', x, y);
eventEmitter.emit('myEvent', x, y);
eventEmitter.emit('myEvent', x, y);
console.log('finished')
}
var count = 0
function f2(x, y) {
count++;
console.log('from f2 function', x, y, count)
}
f1(1, 2)
The current output of this code snippet is as follows:
alok@alok-HP-Laptop-14s-cf3xxx:~/tmp/test-node$ node alok.js
received 1 2
from f2 function 1 2 1
from f2 function 1 2 2
from f2 function 1 2 3
finished
However, I am expecting the following output:
received 1 2
finished
from f2 function 1 2 1
from f2 function 1 2 2
from f2 function 1 2 3
I am puzzled by why console.log('finished') is appearing last and the execution seems synchronous. Any thoughts on this?
