I have the below codes, I am trying to access data sent from my backend server in my frontend js. How can I do that?

Express

...
app.get("/", (req, res) => {
  res.render("home", {data} );
});
...

home.ejs

...
<script src="frontend.js"></script>
...

frontend.js

var data = <%=data%>; // this didnt work...

You could directly inject the data variable into javascript on the page.

<% if (data) { %>
     <h2>I have data</h2>
     <script>
        var data = <%= data %>            
     </script>
<% } %>

Another option might be to make an AJAX call back to the server once the page has already loaded, return the data
