Question

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


II


I and II


The for loop is correct

Answer 1

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:

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