Twig vs Volt: What are the differences?

# Introduction

1. Syntax: Twig uses curly braces {{ }} for evaluating variables and expressions, while Volt uses double curly braces {{ }} for echoing variables and single curly braces {% %} for control structures like loops and conditionals.

2. Security: Twig automatically escapes any variable output to prevent XSS attacks, while Volt does not automatically escape variable output, which means developers need to manually escape potentially dangerous content.

3. Functionality: Twig provides various built-in functions and filters, making it easier to manipulate data and customize output, whereas Volt offers a more limited set of functions and filters, requiring developers to write additional custom functions if needed.

4. Caching: Twig has built-in caching functionality to improve performance by storing compiled templates, whereas Volt relies on the Phalcon PHP framework's caching mechanism for caching compiled templates.

5. Extensibility: Twig allows developers to create custom extension functions and filters easily, enabling greater flexibility in extending its functionality, while Volt has limited support for custom extensions, making it less versatile for complex projects.

6. Documentation: Twig has extensive documentation with a large community of users, making it easier for developers to find resources and solutions to common problems, whereas Volt has less documentation and a smaller user base, which can make it more challenging to troubleshoot issues and learn best practices.

In Summary, Twig and Volt differ in terms of syntax, security, functionality, caching, extensibility, and documentation, providing developers with distinct options for templating engines in web development.
