I have this code in an EJS file:
<table>
<% for(var i=0; i < data.length; i++) { %>
<tr>
<td><%= data[i].id %></td>
<td><%= data[i].name %></td>
</tr>
<% } %>
</table>
When I comment it this way,
<!-- <table> -->
<!-- <% for(var i=0; i < data.length; i++) { %> -->
<!-- <tr> -->
<!-- <td><%= data[i].id %></td> -->
<!-- <td><%= data[i].name %></td> -->
<!-- </tr> -->
<!-- <% } %> -->
<!-- </table> -->
I still have an error in Line 2. Here is the stack of the error:
ReferenceError: c:\Users\toumi\Desktop\workspaces\eclipse\ToDoList\views\x.ejs:2

How can I comment this code?
480
Multiline (Block) Comments Javascript multiline comments, also known as block comments, start with a forward slash followed by an asterisk (/*) and end with an asterisk followed by a forward slash (*/).
JavaScript comments can be used to explain JavaScript code, and to make it more readable. JavaScript comments can also be used to prevent execution, when testing alternative code.
There is two solutions:
<%# comment %> (it's from documentation)<%/* comment */%> (it works too, but it's pretty ugly and uncomfortable for use)I don't see a difference between those examples except highlighting syntax in an IDE (example with the Brackets IDE).

Sample of the <% /* */ %> format for multi-line.
<% /* %>
<div>
<span>This will not be rendered</span>
<% for(var i=0; i < data.length; i++) { %>
<span>These won't be rendered either.</span>
<% } %>
</div>
<% */ %>
It says here about the comments as well that you can comment like below:
<%# code %>
There are two ways to do it!
As mentioned in the documentation of EJS:
<%# commented out code %>
<%/* multiple lines commented out code*/%>
For example:
<%# include('includes/head.ejs') %>
</head>
<body>
<%# include('includes/navigation.ejs') %>
<h1>Page Not Found!</h1>
<%- include('includes/end.ejs') %>
I found this helpful for me. It's simple, multiline and does not conflict with anything.
<%if(false) {%>
<ul>
<% for(var i =1; i <= 10; i++) { %>
<li>
Hello this is iteraiton <%=i %>
</li>
<% }%>
</ul>
<%- include('./meow') %>
<%} %>
