Mastering JavaScript Single Page Application Development

Embedded JavaScript (EJS)

EJS is a JavaScript templating engine that works much like Underscore.js and also uses ERB <% %> style delimiters. Alternatively, it also allows the use of [% %] style tags for delimiters.

Just like Underscore.js, EJS allows arbitrary JavaScript to be parsed when used with the standard <% %> ERB style syntax, and allows the evaluation of expressions using an equals sign = following the opening delimiter tag <%= %>:

<ul> 
<% for (var i = 0; i < people.length; i++) { %> 
    <li><%= firstName %> <%= lastName %></li> 
<% } %> 
</ul> 

This template can be used to iterate over a list of objects from which key names are evaluated as variables with different values:

{ "people": [ { "firstName": "Peebo", "lastName": "Sanderson" }, { "firstName": ...
