My instructions were to iterate through a string and remove all instances of the letter "a". I thought that it would be easy to find examples, but I was unable to do so. Some would remove the letter without the iteration, but that is not what the instructions asked. If someone could please look at my code and assist me in my task I would greatly appreciate it! The "removeA" function will iterate through the string now, and only console logs the !== "a", but for the life of me I can't figure out how to save it to a new string. Thanks in advance.

```
removeA = function(stringWithA) {
    if (stringWithA === null || typeof (stringWithA) !== "string" || stringWithA === "") {  //Checking for is null AND is not array
        return 'Please enter a valid string';
    } else {
        lowerWithA = stringWithA.toLowerCase();
        for (var i = 0; i < lowerWithA.length; i++) {
            if (lowerWithA.charAt(i) !== "a") {
                console.log(lowerWithA.charAt(i));
            }
        }
    }
}

```
