Can I use Multiple useEffects in a single Component?

Using the useEffect hook we can inform the react that we need some data after component render. It can handle any side effect in your component data.

React allow us to use multiple hooks in a single component. For example, we need multiple states in a single component so we can easily utilize multiple useState hooks in one particular component.

• const [data,setData]= useState(24);
• const [data1,setData]= useState(25);

same like as useState, we can also utilize multiple useEffects in one functional component. Its depend on case study where you need to implement multiple useEffects.
