Where is my syntax error?

Code challenge says I have a syntax error. I have been going over this for an hour now and can't find it. Any suggestions?

<!DOCTYPE html>
<html lang="en">
    <title>JavaScript Foundations: Functions</title>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
    <h1>JavaScript Foundations</h1>
    <h2>Functions: Return Values</h2>
      function arrayCounter(myArray){
        if(myArray.isArray() === true){
          return array.length;
        else if(typeOf myArray === 'undefined'){
          return 0;
          return 0;

It should be typeof not typeOf.
