API / Apache FreeMarker Interview questions

What is the purpose of the <#if> directive?

<#if> lets a template branch its output based on a boolean condition, the same role an if-statement plays in a programming language. It supports <#elseif> for additional conditions and <#else> for a fallback, and must always be closed with </#if>.

<#if user.role == "ADMIN">
  Welcome, administrator.
<#elseif user.role == "EDITOR">
  Welcome, editor.
<#else>
  Welcome, guest.
</#if>

Conditions can use comparison operators, boolean logic (&&, ||, !), and the existence-test operator ?? to safely check whether a variable is present before comparing it.
