JavaScript JavaScript Foundations Functions Return Values

Having trouble with return value challenge. I keep getting zero with all values.

Not sure what I'm doing wrong. I understand the function and return value but don't quite understand how to make the if(type of) work for me.

index.html
<!DOCTYPE html>
<html lang="en">
  <head>
    <title>JavaScript Foundations: Functions</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Functions: Return Values</h2>
    <script>
      function arrayCounter(array) {
        if(typeof array === 'string','number', 'undefined'){
          return 0;
        }
        return array.length;
      }



    </script>
  </body>
</html>
