Welcome, you're important. 😊

Hey there [ your name ] 👋🏽, I'm Miracle Ifeanyichukwu and you're welcome to my very first blog post ☺️. I blog about web development related topics - mostly JavaScript 😁. So get subscribed if you're interested in those topics, I'm looking forward to also building a community with y'all 😊.

So to the topic at hand, the useState hook.

What is the useState hook? 🤔

So basically, the useState hook is a function that returns an array that holds two items.

const [ state, setState ] = useState(initialState);

So from the above code snippet, the useState hook is destructured and we can see two items in the array, first is the state which takes the value of the argument passed into the useState hook, ( i.e state takes the value of initialState . The initialState can be of any data type - string, Boolean, object, number etc. ) and the other item, setState is a function used to which is used to update state.

So, The useState hook is a way for functional components in React to manage state. You can think of useState as a way to create a "stateful" variable inside a functional component.

Using the useState hook. 👨‍💻

To use the useState hook, you need to import it from the react library. Then, you can call it inside your functional component like this:

import { useState } from 'react'

function MyComponent() {

const [state, setState] = useState(initialValue)

// Your component logic goes here

}

When can I use the useState hook?? 🤔

Once you have your state and setState variables, you can use them in your component like any other variables. For example, you can use the state variable to render dynamic content, and you can use the setState function to update the state in response to user input or other events.

In Summary.

Overall, the useState hook is a great way to add state management to your functional components. It's simple to use and makes it easy to build powerful and interactive components.

This is the most important things about the useState hook in React js.. I am sure it would be of help 🤝🏽.

Keep on coding...

Catch you later 😉.
