Conditionals

If/Else Statements

Conditionals in EJS work exactly like JavaScript. No new syntax to learn—just plain if/else blocks wrapped in EJS tags.

<% if (user.isLoggedIn) { %>
  
Welcome back, <%= user.name %>!
<% } else { %>
  
Please log in.
<% } %>
    

The logic is clear and readable. Your HTML structure stays intact around the conditional blocks.

Else If Chains

Need multiple conditions? Chain them with else if:

<% if (score >= 90) { %>
  
Grade: A
<% } else if (score >= 80) { %>
  
Grade: B
<% } else if (score >= 70) { %>
  
Grade: C
<% } else { %>
  
Grade: F
<% } %>
    

Works just like you'd expect. The conditions are evaluated in order.

Ternary Operator

For simple conditionals, the ternary operator keeps things concise:

<%= user.isAdmin ? 'Admin Dashboard' : 'User Dashboard' %>
    

Short, sweet, and perfect for inline conditions where a full if block would be overkill.

Logical AND Shorthand

Want to show something only if a condition is true? Use &&:

<% if (user.isPremium) { %>
  Premium Member
<% } %>
    

Or even shorter with && for output:

Discount: <%= isPremium && '20% off' %>
    

The && operator returns the second value if the first is truthy. Neat trick for quick conditional output.
