Why is my alert box not popping up? 

function isFieldEmpty() {
    const field = document.querySelector('#info');
    if (field.value ==== '') {
        return true;
    } else {
        return false;
    }
}

const fieldTest = isFieldEmpty();

if (fieldTest === true) {
    alert("Please provide your information.");
}

Here is my HTML code:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>JavaScript Functions</title>
    <link href="css/style.css" rel="stylesheet"> 
  </head>
  <body>
    <main>
      <input type="text" id="info">
    </main>
    <script src="js/multiple.returns.js"></script>  
  </body>
</html>

Figured it out!

File name was incorrect. I fixed it to read 

<script src="js/multiple-returns.js"></script>

You have four equal signs on line 3.

function isFieldEmpty() {
    const field = document.querySelector('#info');
    if (field.value ==== '') {     👈
        return true;
    } else {
        return false;
    }
}

No error for that?
