dynamically add two input field when button click in react js

creating a react application that dynamically adds input fields when a button is clicked is a common task. this tutorial will walk you through the process of implementing this feature step by step.

step 1: setting up your react environment

if you haven't already set up a react environment, you can quickly create one using create react app. open your terminal and run:

step 2: create the main component

step 3: use the component in your app

step 4: run your application

now that you have set up everything, you can run your application. if you are still running `npm start`, you should see the application in your browser.

step 5: test the functionality

you should see a text input field and two buttons: "add input field" and "submit". clicking the "add input field" button will add a new input field, and you can type in each of them. when you click "submit", the current input values will be logged to the console.

summary

in this tutorial, you learned how to create a dynamic form in react that allows users to add input fields on demand. the key concepts covered include:

- managing state with the `usestate` hook.
- handling input changes and updating the state.
- dynamically rendering components based on the state.

this pattern can be extended for various use cases, such as forms with different types of inputs or managing more complex data structures. you can also apply validation, styling, and other functionalities to enhance this basic implementation.
