Web Scraping Libraries provide functions and methods to facilitate web scraping. These libraries offer tools to send HTTP requests, parse and navigate HTML or XML documents, and extract data from web pages. Common web scraping libraries include Beautiful Soup, Requests, and lxml in Python, and Cheerio and Axios in JavaScript. They simplify the process of interacting with web pages and retrieving data, making it easier for developers to write scripts that can handle various web scraping tasks. These libraries are essential for creating custom scrapers tailored to specific data extraction needs.
