🌐 The Backbone of Web Interactions

Welcome to the dynamic world of backend development, where we unveil the magic behind web experiences. While backend development spans many fields, this course will hone the backend's role in crafting interactive web experiences. In this chapter, we'll dive deeper into the specific aspects of backend development that pertain to the web environment.

🤔 Why Do We Need Backend Development?

Backend development is like the engine of a car. It powers everything behind the scenes, like storing data securely, doing calculations, and making sure everything works together smoothly. It's what makes apps and websites run properly, even though you don't see it directly.

Imagine 💭 you're using a social media app:

1. Data Storage: The Backend stores your posts, photos, and info safely so you can access them anytime;
2. Security: It keeps your account safe by ensuring only you can access your stuff;
3. Making Things Work: When you post something, the backend figures out where to put it, who can see it, and how to show it to others;
4. Notifications: It sends notifications when someone likes your post or sends you a message;
5. Search: The Backend finds what you want when searching for friends or topics;
6. Fast Responses: It responds quickly when you want to see your feed, even when many people use the app.

The best part 🎉 is that YOU can independently develop 👩‍💻 both the Frontend and Backend of your app using only JavaScript.
