## Summary
Template language is a scripting language used to write templates, which are reusable patterns for generating content. It is typically processed by a template processor to produce final output, such as HTML or reports. Template languages simplify content generation by separating structure from logic.

## Key Facts
- Template language is a subclass of scripting language, designed for run-time events.
- It is used by template processors to generate final output.
- Common examples include Jinja (for Python), JSX (for React), and DocuDraft (for legal reports).
- Template languages often avoid inline code to keep documents cleaner.
- The first known use of JSX was in 2013 as an extension to JavaScript syntax.
- Template languages are widely used in web development and report generation.

## FAQs
### Q: What is the difference between a template language and a programming language?
A: A template language is a specialized scripting language designed for writing templates, while a general-purpose programming language can perform a wide range of tasks. Template languages focus on generating structured output efficiently.

### Q: Can template languages be used outside of web development?
A: Yes, template languages are used in various domains, including legal report generation (e.g., DocuDraft) and document processing, where they help automate content creation.

### Q: How does JSX differ from other template languages?
A: JSX is an extension of JavaScript syntax introduced in 2013, allowing developers to write HTML-like structures within JavaScript code. It is specifically designed for use with React.

### Q: What is the most popular template language?
A: Jinja is one of the most widely used template languages, particularly in Python-based web frameworks like Flask and Django.

### Q: Are template languages secure?
A: Template languages can be secure if properly implemented, but they may introduce vulnerabilities if user input is not sanitized. Best practices should be followed to mitigate risks.

## Why It Matters
Template languages play a crucial role in modern software development by simplifying the process of generating structured content. They separate the presentation layer from business logic, making applications more maintainable and scalable. For example, Jinja and JSX enable developers to create dynamic web pages efficiently, while DocuDraft automates legal report generation. By reducing redundancy and improving consistency, template languages enhance productivity and reduce errors in content creation. Their ability to integrate with various programming languages further extends their utility across different domains.

## Notable For
- Serves as the foundation for modern web templating systems like Jinja and JSX.
- Introduced in 2013 as an extension to JavaScript syntax, enabling React developers to write HTML-like structures within JavaScript.
- Used in legal practices for generating standardized reports, such as DocuDraft.
- Designed to avoid inline code, promoting cleaner and more readable documents.
- Supports dynamic content generation, making it essential for web development and document processing.

## Body
### Definition and Purpose
Template language is a scripting language used to write templates, which are reusable patterns for generating content. It is processed by a template processor to produce final output, such as HTML or reports. The primary purpose is to separate structure from logic, improving maintainability and scalability.

### Classification and Relationships
Template language is a subclass of scripting language, designed for run-time events. It is related to other templating systems like JSX, Jinja, and DocuDraft, each tailored for specific use cases. JSX, introduced in 2013, extends JavaScript syntax for use with React, while Jinja is a Python-based web template engine.

### Usage and Examples
Template languages are used in web development, legal report generation, and document processing. Examples include:
- **JSX**: An extension of JavaScript syntax for React.
- **Jinja**: A Python-based template engine for web development.
- **DocuDraft**: A templating language for legal report generation.
- **Haml**: A templating system designed to avoid inline code in web documents.

### Security Considerations
While template languages offer efficiency, they require careful handling of user input to prevent security vulnerabilities. Best practices should be followed to ensure safe implementation.
