- The internet primarily consists of websites, with Cloudflare's service handling over 300,000 requests per second.
- Serving clients one at a time doesn't scale, so concurrency is needed to handle multiple clients simultaneously.
- JavaScript lacks native threads, leading to callback-based concurrency known as 'callback hell' before async/await was introduced.
- Async/await simplifies asynchronous code, making it more readable and manageable, as shown by converting callback-heavy code to a cleaner async structure.
