React Hooks Tutorial - 6 - Fetching data with useEffect

React Hooks are revolutionising the way we develop in React and solving some of our biggest concerns. The useEffect Hook allows us to replace repetitive component lifecycle code.

Essentially, a Hook is a special function that allows you to “hook into” React features. Hooks are a great solution if you’ve previously written a functional component and realize that you need to add state to it.

In this example we are explaining how to use useEffect as componentDidMount

When the user lands on our page, we want to call the API. In other words, we want to call the API during the mounting part of the component's lifecycle.

Then, let's create an asynchronous function to fetch our data. An asynchronous function is a function that needs to wait after the promise is resolved before continuing. In our case, the function will need to wait after the data is fetched (our promise) before continuing.
The function we just created is wrapped in a try...catch statement so that the function catches the errors and prints them in the console. This helps debug and prevents the app to crash unexpectedly.
