React useEffect and HTTP calls
- 08/06/2022
The motivation behind the introduction of useEffect Hook is to eliminate the side-effects of using class-based components. For example, tasks like updating the DOM, fetching data from API end-points, setting up subscriptions or timers, etc can be lead to unwarranted side-effects. Since the render method is to quick to produce a side-effect one needs to use life cycle methods to observe the side effects. For example, consider updating the document title for a simple counter component to the current value. On the initial render, we set the current clicked value to 0 clicks. So, this section is coded into the componentDidMount() method which is executed only once in the component life cycle.
