Mustache vs Pug vs TypeScript: What are the differences?

# Introduction
Your task is to perform the following actions:
- Format everything as Markdown code that can be used in a website.
- Provide the Key differences between Mustache and Pug and TypeScript . Be specific 
- Differences should not be more than 6. Be specific.
- Each difference should be in a single paragraph  
- Extract and remove generic/declarative sentence
- Subheadings must be bold and in number points not bullet points
- Summary should be in one line only

1. **Syntax**: Mustache uses {{ }} for templating, while Pug uses indentation to denote structure, and TypeScript enforces statically typed syntax.
2. **Functionality**: Mustache is logicless and primarily focuses on data binding, Pug allows for more complex logic and operations, and TypeScript provides type checking during compile time. 
3. **Extensibility**: Mustache is limited in its functionality and requires additional libraries for advanced features, Pug has built-in features like mixins and includes for modularity, while TypeScript supports class-based inheritance and interfaces for structuring code. 
4. **Error Handling**: Mustache may not provide detailed error messages, Pug offers more descriptive error messages during compilation, and TypeScript catches potential errors at compile time, reducing runtime errors. 
5. **Rendering Speed**: Mustache's rendering speed might be slower due to its simple logic, Pug's compilation process can be faster because of its concise syntax, and TypeScript’s transpilation process might take longer but results in optimized JavaScript code. 
6. **Community Support**: Mustache has been adopted widely across various languages, Pug has a robust community supporting its development and offering plugins, while TypeScript has strong community backing from Microsoft and many open-source contributors. 

In Summary, the key differences between Mustache, Pug, and TypeScript lie in their syntax, functionality, extensibility, error handling, rendering speed, and community support.
