When scraping a website using Puppeteer, it's crucial to wait for all necessary elements to be fully loaded before interacting with them, especially for JavaScript-rendered content.
Puppeteer provides methods like waitForNetworkIdle, waitForSelector, and waitUntil to control the timing of page interactions and ensure complete page loading.
Using waitForNetworkIdle helps in waiting for the page to finish all network requests, vital for JavaScript-heavy pages with ongoing requests.
WaitForSelector is useful for waiting for specific elements to load, while the waitUntil option offers control over when Puppeteer considers navigation complete.
