Why does this JavaScript code print an unexpected result?
I came across this small JavaScript example and the output surprised me.
for (var i = 0; i < 3; i++) {
setTimeout(function () {
console.log(i);
}, 1000);
}
When this runs, the output is:
3
3
3
But I expected it to print:
0
1
2
Why does this happen in JavaScript?
What would be the correct way to fix this behavior?
