Open any AI chatbot and type a question. Watch the response appear. It doesn't pop up all at once. It flows in word by word, like someone typing in real-time. That's streaming, and it completely changes how your app feels to use.

Without streaming, a user clicks "Generate" and stares at a blank screen for 5, 10, maybe 15 seconds waiting for the full response. They wonder if it's broken. They might click again. It feels slow and frustrating.

With streaming, the first words appear in under a second. The user starts reading immediately while the rest generates. The same total wait time feels three times faster because there's constant visual feedback. Streaming isn't just a technical feature. It's a user experience superpower. Building it requires a different approach to handling API responses, and that's what you'll learn today.
