Here's a basic outline of how this process works:
Fetching Data: To pull data from an
API, JavaScript is often used to make asynchronous requests using the
fetch() function. This function sends an HTTP request to
the API endpoint and waits for a response.
Receiving Data: Once the API responds, the data is typically returned in JSON format. JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy to work with in JavaScript.
Using the Data: After receiving the data, it can be processed and displayed on the web page as needed. This can involve updating the DOM (Document Object Model) to insert the data into specific HTML elements.
Saving Data Locally: In some cases, it may be desirable to save the retrieved data for offline use or to improve performance. Local storage, a feature provided by web browsers, allows developers to store data as key-value pairs in the user's browser. JSON is often used to serialize and deserialize data when saving and retrieving it from local storage.
By following these steps, web developers can seamlessly integrate data from external APIs into their applications, providing users with dynamic and up-to-date content.
