How can I use if statement in ejs?

Question

I have a page that makes a foreach and show some photos like this

<% imgs.forEach(function(img) { %>
      <img src="uploads/<%=user.username%>/screenshots/<%= img %>">
 <% }); %>

And I want make a if statement because, in case that not photos to show gives a message like this:

"no photos uploaded"

Something like this:

<% if(imgs.length > 0){ %>
    <% imgs.forEach(function(img) { %>
        <img src="uploads/<%=user.username%>/screenshots/<%= img %>">
    <% }); %>
<% } else{ %>  
    <p>no photos uploaded</p>
<% } %>

This works well but do ejs support nested if else loop? – xetryDcoder Dec 31 '20 at 15:36
@xetryDcoder I have not tried it, but it should work the same way single `if-else` works. Let me know if you face any issues. – Shaharyar Dec 31 '20 at 18:05

The shorthand version is correct, but it does have a syntax error

<%= role === 'admin' ? 'Super Admin' : 'Admin' %>

Or

<% if(role === 'admin'){ %>
    <p>Super Admin</p>
<% } else{ %>
    <p>Admin</p>
<% } %>

It should actually be `<%= role == 'A' ? 'Super Admin' : 'Admin' %>`, with only one `?`. Your code results in a Syntax Error – May 11 '22 at 23:50
My bad it was a typo .. thanks – Abderrahim Soubai-Elidrisi May 12 '22 at 02:00

Do you mean something like this...?

<% if (kindOfDay === "Sarturday" || kindOfDay === "Sunday") { %>
  <h1 style="color: green;"><%= kindOfDay %> Todo List</h1>
<% } else { %>
  <h1 style="color: blue;"><%= kindOfDay %> Todo List</h1>
<% } %>
