Advantage and disadvantage of Web Scraping Javascript?
One advantage of web scraping with JavaScript is the ability to interact with dynamic and interactive content on websites. JavaScript can be used to navigate through pages, click buttons, and extract data from elements that are loaded dynamically. This makes it easier to scrape data from modern websites that heavily rely on JavaScript for their functionality. However, a major disadvantage of using JavaScript for web scraping is that it can be more complex and resource-intensive compared to traditional scraping methods. JavaScript rendering requires more processing power and may be slower than other scraping techniques, especially when dealing with large amounts of data or complex websites. In conclusion, while JavaScript can offer more flexibility and access to dynamic content, it may come with performance trade-offs and technical challenges.
