<!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'||typeof array ==='number'||
            typeof array ==='undefined'){
            return 0;
        }      
        else(){ 
            return typeof array.length ;
        }
      }


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

Hello Mickey,

Your code is mostly right like you said. The issue is with the else part of you conditional statement. Else doesn't take a condition.

so the javascript should be

function arrayCounter (array){

        if (typeof array === 'string'||typeof array ==='number'||
            typeof array ==='undefined'){
            return 0;
        }      
        else { 
            return typeof array.length ;
        }
}

Hope this helps

Ali M
