SDK for JavaScript | Apify Documentation
Four years ago, Apify released its open-source Node.js library for web scraping and automation, Apify SDK. It became popular among the community, but there was a problem.

JavaScript "loose" comparison step by step When you start learning JavaScript, you will likely read about preferring to use === over == to compare values.
