] | In a browser environment, you can assign variables by setting a property of the `window` object:
```js
for (let i = 0; i < 8; i++) {
window["a"+i] = "something "+i;
}
console.log(a2, a3);
```
As for your code, use this:
```
window["a"+i] = $('[name="answer['+i+']"]:checked').val();
```
In the `for` loop | What I can think of is this
```
var i;
for (i = 1; i < 8; i++) {
let a[i] = $('[name="answer['+i+']"]:checked').val();
}
