• Navigating Data Access Barriers: Evaluating application programming interfaces (APIs) as a alternative to scraping, with practical examples.
• Scalable Data Collection: Designing algorithms for systematic pagination and multi-page data harvesting using iterative functions.
• Limitations of Static Scraping: An introduction to dynamic content rendered by JavaScript and an overview of advanced tools (e.g., `RSelenium`) for programmatic browser control.
