Javascript Question

I want to reduce n to 0 on the last iteration but my calculations are wrong. Im overlooking something. Right now im doing Math.round(n / loops). I need to find a way to disperse the substraction in such a way so that in the last iteration n becomes 0 while the range between each n´s is constant.

`function check(a, b) {`

let loops = a / b;

let n = 200;

for (let i = 0; i <= loops; i++) {

console.log(n);

n -= Math.round(200 / loops);

}

}

check(60, 10)

Edit: Im sorry but these downvotes are ridiculous.

The main problem with your code is that the expression `n / loop`

is different in each iteration. You might have intended that this expression was constant, in which case the logic would have been more reasonable.

Use a separate variable that starts with the value of `n`

and then is the subject of the subtractions, but *without* changing the original value of *n* that is used in the expression `n / loop`

:

```
function check(a, b) {
let loops = a / b;
let n = 200; // don't change n after this.
let n2 = n; // use a separate variable for that.
for (let i = 0; i <= loops; i++) {
console.log(Math.round(n2)); // only round in output
n2 -= n / loops; // use n, but only change n2
}
}
check(60,10);
```
