js.forEach is not a function

The error "js.forEach is not a function" occurs when you try to use the `forEach` method on a variable that is not an array or does not have the `forEach` method defined on it.
Please make sure that the variable you are using with `forEach` is indeed an array. If it is not, you can convert it into an array before using `forEach`. Alternatively, ensure that you spelled `forEach` correctly and that it is available in the version of JavaScript you are using.
Here's an example of correct usage of `forEach` with an array:
```javascript
const array = [1, 2, 3];
array.forEach((element) => {
console.log(element);
});
```
Make sure to double-check your code and verify that you are using `forEach` on an appropriate variable.
