App Weather Api in App Development
An API (Application Programming Interface) allows your app to communicate with external services to get or send data.
The fetch() function in JavaScript is used to make HTTP requests to APIs and returns a Promise.
Most APIs return data in JSON format, which you parse using response.json().
API keys are unique identifiers that authenticate your requests — never expose them in public frontend code.
Error handling with try/catch and loading states are essential for a good user experience when using APIs.
