# --description--
Within your loop, you need to check if the character in `strArray` at index `i` is not a `+`, `-`, or a space. If it is not, `push` it to the `cleanStrArray`.
You will need to check if the array `["+", "-", " "]` does not include the current character. You can use a combination of the <dfn>includes()</dfn> method and the <dfn>!</dfn> operator to do this.
The `.includes()` method returns `true` if the array contains the character, and `false` if not. The logical NOT operator (`!`) will return the opposite of the value of the `.includes()` method.
Here is an example:
Here is an example checking if the current character is not in the vowels array. If it is not, that current character is pushed into the `consonantArray`:
```js
const numbersArray = [1, 2, 3, 4, 5]
const number = 6
const inputString = "Hello World";
const charArray = inputString.split('');
const consonantArray = [];
if (!numbersArray.includes(number)) {
console.log("The number is not in the array.")
for (let i = 0; i < charArray.length; i++) {
if (!['a', 'e', 'i', 'o', 'u'].includes(charArray[i])) {
consonantArray.push(charArray[i]);
}
}
```
Within your loop, you need to check if the character in `strArray` at index `i` is not a `+`, `-`, or a space. If it is not, `push` it to the `cleanStrArray`.
