I am attempting to replicate a rather simple example from this question here
<div <% if (page_name === 'overview') { %> class="menu__menu-overviewPage menu" <% } %> class="menu">
However, when I try it on any page other than overview, I encounter an error stating that page_name is not defined
I find it puzzling how in most programming scenarios, if/else statements can handle undefined or undeclared variables, except in ejs. How can I work around this issue?
In this scenario, Javascript will consistently generate an error.
It is crucial to distinguish between a variable being undefined and a variable not being defined at all.
If you have not previously declared the variable, it cannot be compared to anything because it does not exist. This leads to an error, as expected.
