Props and/or state are used by a React component to generate the output.
If the component makes calculations that don't target the output value, then these calculations are named SIDE-EFFECTS
Fetch requests, direct DOM manipulation, the use of timer functions like setTimeout(), and other actions are examples of side effects.
The side-effect logic is independent of component rendering. It is a mistake to carry out side-effects directly in the component's body
You have no control over how frequently the component renders;
and to decouple rendering from the side-effect and we have useEffect Hook
This video will also help you to understand, different ways of implementing useEffect Hook by understanding different Life Cycle methods

I have learned and used many times useEffect() hooks many places. But i never understood properly how useEffect() hooks works in different scenarios like mounting, updating and unmounting phase in same as working in class based Component. Your way of explanations are very helpful and concise . Thank you for making amazing series on KZfaq. Thank u 🙏🙏

Hi Nisha, QQ; I’ve couple of them. 1. ReactJs follow virtual DOM methodology, which as per your explanation from previous video’s means only changed/updated elements get reflected on browser. Here, User functional component is getting triggered even though there are no changes of it own. How is this happening? 2. useEffect hook, is only restricting the code written within ‘useEffect’ function in mounting stage, remaining code outside of useEffect() is getting executed. In Updating stage, code outside and inside of useEffect() both are getting executed then, what is the exact purpose of useEffect? Correct my understanding. Thanks.
