What is EJS?
So you want to learn EJS. EJS stands for Embedded JavaScript. It's a simple templating language that lets you generate HTML markup with plain JavaScript. Think of it as a way to sprinkle dynamic content into your HTML without fighting the syntax.
Unlike some other template engines that force you to learn a new language, EJS is literally just JavaScript inside HTML. If you know JavaScript, you already know 90% of EJS. That's the beauty of it.
How EJS Works
EJS works by taking a template file and mixing it with data to produce final HTML. It runs on the server, so the browser never sees the EJS code—just the rendered output.
Hello, <%= name %>!
You have <%= messages.length %> new messages.
See that? The <%= tags get replaced with actual values. The rest stays as regular HTML. Simple as that.
Why Choose EJS?
There are plenty of template engines out there—Handlebars, Pug, Nunjucks. So why EJS?
First, the learning curve is almost zero. You don't need to learn a new syntax. Second, it's just JavaScript. Loops, conditionals, variables—all work the way you expect. Third, it outputs real HTML. No indentation-based syntax, no special block helpers.
Trust me, once you try EJS, you'll wonder why you ever struggled with other template engines.
Real HTML with Logic
The real power of EJS is that you write normal HTML and add logic where you need it. Need a list? Just use a for loop. Conditional content? Use an if statement. It's that straightforward.
<% if (user.isAdmin) { %>
Welcome back, Admin!
<% } else { %>
Welcome, <%= user.name %>!
<% } %>
This keeps your templates readable and your code maintainable. No magic, just JavaScript.
