<h2>
Challenges and Limitations
</h2>
<h3>
Learning Curve
</h3>
<p>
Angular has a steeper learning curve compared to some other frameworks, especially for beginners. Understanding its concepts, architecture, and best practices requires a significant investment of time and effort.
</p>
<h3>
Project Size and Complexity
</h3>
<p>
Angular is a powerful framework that excels in building complex applications, but it may be overkill for smaller projects. For simpler applications, other frameworks or libraries might be more efficient choices.
</p>
<h3>
Performance Optimization
</h3>
<p>
While Angular offers excellent performance, optimization is crucial for large and complex applications. Techniques like lazy loading, change detection strategies, and component optimization are essential for maintaining responsiveness.
</p>
<h3>
Community Support
</h3>
<p>
While Angular has a large and active community, specific issues or niche use cases might require more specialized knowledge or support.
</p>
<h2>
Comparison with Alternatives
</h2>
<h3>
Angular vs. React
</h3>
<p>
Angular and React are two popular JavaScript frameworks with distinct approaches. Angular is a more opinionated framework that emphasizes structured development and built-in features, while React is more flexible and allows for greater customization. The choice between them depends on your project's specific requirements and the preferences of your team.
