Welcome! Today, we will learn how our React apps can fetch data from servers using a library known as Axios. Simply put, Axios helps us request information from other applications (servers) through APIs or the Application Programming Interface.

APIs are sets of guidelines that allow communication between software. They often send and receive data in a format called JSON, which stands for JavaScript Object Notation. An API response may look like:

Remember, when working with JSON data from APIs, it might come as an array of objects, or sometimes just a single object. 😊 Always check the structure of the data you receive and adjust your code accordingly!

You can check the structure of the data returned from the API by going to API link in your browser. Try going to "https://api-regional.codesignalcontent.com/posting-application-2/posts/" to inspect the structure of the data we will be using in this lesson. You will see that the API returns a JSON object that is an array of objects, each object including  the keys id, text, authorId, and likesCount.
