Can't get ejs value into script variable?

Whenever I attempt to set a variable within a script to be equal to an array rendered using ejs I get 'Invalid are unexpected token'.

Here is the snippet:

    <script type="text/javascript">
        var list = <%= events.slice(0) %>;
    </script>

Originally I had it set to:

    <script type="text/javascript">
        var list = <%= events %>;
    </script>

But I receive the same error. I was pretty certain you could render an ejs file that contains script tags and set the ejs variable to a variable within the script tag. Am I wrong?

Events is an array of event models for a calendar.

You don't need to add script tags. Just put your code in html

Here is a plain example

index.ejs

<script>

//just call the events variable

for(var i = 0; i < events.length; i++){
    var myEvent = events[i];
    //handle the event
 }

//then use the variables outside the script tag after you are done with all the handling

</script>

<ul>
<li><%=myDefinedVariable%></li>
<% var name = "Jake" %>
<li><%=name%></li>

<%for(var i = 0; i < 10; i++){%>
<li><%=name%></li> // puts li in the ul 10 times
<%}%>
</ul>

this is what you are looking for:

<script type="text/javascript">
    var list = <%-JSON.stringify(events)%>;
</script>
