Can't pass the task

Hello. I can't pass the task. It says I'm missing the function called arrayCounter(). What's wrong with my code? I don't get it.

function arrayCounter (arr) {
    if((typeof arr === 'string') or (typeof arr === 'number') or (typeof arr === 'undefined')) {
          return 0;
    }
    return arr.length;
}

You should use the "||" (or operator) rather than the word "or". See the code below

function arrayCounter (arr) {
    if((typeof arr === 'string') || (typeof arr === 'number') || (typeof arr === 'undefined')) {
          return 0;
    }
    return arr.length;
}

Other than that everything was perfect.
