What is wrong with this for loop?

for (let i = 0, i < 10, i + 1) {
move();
}
JavaScript
I. The for loop uses commas instead of semicolons

II. It should say i++ instead of i + 1

I and II

The for loop is correct

1 answer

The correct answer is I and II.

Here are the reasons:

I. The for loop uses commas instead of semicolons: In a for loop in JavaScript, the three components (initialization, condition, and increment) must be separated by semicolons (;), not commas (,).

II. It should say i++ instead of i + 1: The incrementer part of the for loop should ideally use i++ (or i += 1, or i = i + 1), but i + 1 by itself does not update the value of i.

Therefore, both points indicate issues with the for loop syntax and logic. The corrected loop should look like this:

for (let i = 0; i < 10; i++) {
    move();
}
