for-of in Firefox

# Axel Rauschmayer (11 years ago)

Does Firefox not yet do the one binding per loop iteration? I would have expected the output 0 in the following code.

let arr = [];
for (let i of [0, 1, 2]) {
    arr.push(() => i);
}
console.log(arr[0]()); // 2

Does Firefox not yet do the one binding per loop iteration? I would have expected the output `0` in the following code.

```js
let arr = [];
for (let i of [0, 1, 2]) {
    arr.push(() => i);
}
console.log(arr[0]()); // 2
```
