Handlebars.js vs Pug vs TypeScript: What are the differences?

# Introduction
This Markdown code provides key differences between Handlebars.js, Pug, and TypeScript.

1. **Syntax**: Handlebars.js is a logicless templating language with simple and clean syntax using double curly braces for placeholders, while Pug uses indentations and whitespace for defining tags and elements. TypeScript, on the other hand, is a superset of JavaScript that adds optional static typing.
2. **Code Readability**: Pug focuses on simplicity and clean code by reducing redundant characters like closing tags, making the code more readable and concise. Handlebars.js allows developers to write HTML elements more naturally without much alteration. TypeScript enhances code readability and maintainability by providing type checking and interfaces.
3. **Error Handling**: Handlebars.js has better error-handling capabilities, providing detailed error messages for easy debugging. Pug can be more strict in syntax, which may make it harder to work with for beginners. TypeScript catches errors during development due to its static typing, reducing bugs and improving code quality.
4. **Extensibility**: Handlebars.js has a vast number of plugins available for extending its functionality to handle more complex logic. Pug also supports mixins and filters for modularity and reusability. TypeScript offers better compatibility and integration with existing JavaScript libraries and frameworks.
5. **Performance**: Handlebars.js is lightweight and efficient in rendering dynamic content, making it suitable for high-performance applications. Pug has a higher overhead due to its compilation process, which can affect performance in larger projects. TypeScript provides performance benefits through static typing and early error detection during development.
6. **Community Support**: Handlebars.js has a large and active community, with good documentation and resources available for developers. Pug also has a strong community backing, advocating for its unique templating approach. TypeScript has a growing community and is widely adopted in modern web development projects.

In Summary, the key differences between Handlebars.js, Pug, and TypeScript lie in syntax, code readability, error handling, extensibility, performance, and community support. Each has its unique strengths and use cases in web development.
