It gives a full-featured API for mechanizing web browsers and performing activities like clicking buttons and filling out shapes. The puppeteer can be utilized to scrape data from websites that require JavaScript to operate, which isn't conceivable with conventional web-scratching instruments like Cheerio. Puppeteer is broadly utilized by designers and analyzers to robotize assignments like UI testing, execution testing, and web scratching.
What to Use?
A Cheerio and Puppeteer are both useful tools for web scratching and robotization, but they serve diverse purposes and have diverse qualities.
