What's an API? A metaphorical explanation 💡

Think of API as the waiter in a restaurant, taking orders from the customer (front end), answering questions, communicating these order to the kitchen (backend) and coming back with the kitchen’s response in the form of a meal.

@Fred_Kuzyk: Excellent metaphor.

In short, once the customer places an order, the waiter communicates it to the kitchen team, which acts as the backend. The kitchen then prepares the food and sends it back to the waiter, who delivers it to the customer as a response to their order.

Similarly, an API acts as an intermediary between the front-end and back-end of an application. It receives requests for data or services from the front-end, communicates them to the backend, and then sends the backend’s response back to the front-end.

In summary, the analogy highlights the role of APIs as a means to connect the front-end and back-end of an application and how they help simplify and streamline communication between the two.
