2.1 Concepts and Terminologies
</h3>
<p>
Understanding the fundamental concepts associated with templates is essential for effective utilization:
</p>
<ul>
<li>
<strong>
Template Engine:
</strong>
A software component that takes a template as input and renders it dynamically, replacing placeholders with data to produce the final output. Popular template engines include Jinja2 (Python), Handlebars (JavaScript), and Twig (PHP).

Placeholder:
</strong>
A variable or special symbol within a template that represents a value to be replaced at runtime. Placeholders can be used for text, data, images, or other content.
</li>
<li>
<strong>
Control Structures:
</strong>
Template engines often provide control structures (loops, conditionals) for dynamically generating content based on data.
</li>
<li>
<strong>
Inheritance:
</strong>
Templates can inherit from other templates, allowing for the creation of hierarchical structures and modularity.
</li>
<li>
<strong>
Data Binding:
</strong>
The process of linking data sources to template placeholders, automatically updating the displayed content when the data changes.
</li>
</ul>
<h3>
