# Guess the output of this JS code

Try to guess the output of this code without running it. Let me know in the comment what you got 😉

``````let num = 10;
for(let i = 0; i < num; i++){
console.log(num);
num--;
}
``````

hint: You may have got the first half right

Output (i/num after iteration):
10 (1/9)
9 (2/8)
8 (3/7)
7 (4/6)
6 (5/5) - loop terminates as `!(i < num).`

Nice one!

The solution is:
10
9
8
7
6

The explanation:
1- It'll output 10 since we didn't change it yet.
2- We'll increase i to `1` and num decreased to `9`.
3- Increases i to `2` and num decreased to `8`.
4- Increases i to `3` and num decreased to `7`.
5- Increases i to `4` and num decreased to `6`.
Then it ends, 'cause num will be `5` while i will be the equal, so it stops.

for loop stop when num = 5, ( every console.log in for decrease num for 1 )

Shuvo
