Content developed during the JS Expert training created by Erick Wendel. This in-depth course provided an immersion in advanced JavaScript topics, essential for developing robust and scalable applications.

• Automated Testing: Implementation of unit, integration and end-to-end tests to ensure code quality and reliability.
• JavaScript Lifecycle: In-depth understanding of the lifecycle, including concepts such as Prototype Chaining, Type Coercion, and Call Stack, which are fundamental for optimization and debugging.
• Advanced Data Types: Mastery of structures such as Map, Set, WeakMap and WeakSet, as well as Generators and Iterators, expanding the capacity to manipulate complex data.
• Regular Expressions (RegEx): Application of regular expressions for text validation and processing, using the Fluent API design pattern for building operations pipelines.
• Design Patterns: Implementation of design patterns such as Singleton, Factory and Observer, promoting more modular, reusable and easy-to-maintain code.
• Package Management with NPM: Creating and managing packages, understanding semantic versioning, and best practices for publishing and maintaining libraries.
• Command Line Interfaces (CLI): Developing CLI applications with Node.js, including file manipulation and safe execution of shell commands.
• Streams in Node.js: Work efficiently with data streams, optimizing read and write operations for better performance in high-demand applications.
• Error Handling: Adoption of best practices for capturing and managing exceptions, ensuring resilience and facilitating application debugging.
• Performance Optimization: Analysis and performance improvement in JavaScript and Node.js applications, focusing on profiling techniques and bottleneck identification.
• Long-Running Processing: Using Worker Threads and Child Processes to handle intensive tasks without blocking the event loop.
• JavaScript Security: Implementing security practices to mitigate common vulnerabilities such as code injection and XSS attacks.

Each module has its own README.md with more details and a ref.txt with external references for consultation.
