Make Them Fly.\u003c\/p\u003e\u003cp\u003eYour web scraper takes hours to crawl thousands of URLs. Your API server handles requests one at a time while users sit watching loading spinners. Your data pipeline processes records sequentially, wasting precious wall-clock time on the network.\u003c\/p\u003e\u003cp\u003eYou've heard async programming could fix all of this. You've seen the async and await keywords.
