React useEffect Hook - (Part-1) | Side-Effects in React| Life Cycle Method|UseEffect Hook

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
