Lecture 254:- Playing With EJS

EJS (Embedded JavaScript) is a simple templating language that lets you generate HTML markup with plain JavaScript. It's easy to use and provides a lot of features to make it flexible and powerful.

Here are some basic examples of how to use EJS:

1. Outputting Variables:

   In EJS, you can output the value of a variable by placing it inside <% %> tags. For example, to output the value of a variable named "title", you can use the following code:

   htmlCopy code

   <h1><%= title %></h1>

2. Conditional Statements:

   You can use conditional statements in EJS to generate different content based on certain conditions. For example, to generate content only if a variable "isLoggedIn" is true, you can use the following code:

   htmlCopy code

   <% if(isLoggedIn) { %>  <p>Welcome back!</p> <% } %>

3. Looping over Arrays:

   You can loop over arrays in EJS using the <% %> tags and the JavaScript forEach() method. For example, to generate a list of items from an array named "items", you can use the following code:

   htmlCopy code

   <ul>  <% items.forEach(function(item) { %>    <li><%= item %></li>  <% }); %> </ul>

4. Including Partials:

   EJS allows you to include partial templates using the <% include %> tag. For example, to include a header and a footer partial in your template, you can use the following code:

   htmlCopy code

   <% include header %> <h1><%= title %></h1> <% include footer %>

These are just a few examples of what you can do with EJS. With its simple syntax and powerful features, it's a great choice for generating dynamic HTML content in Node.js applications.
