React Word Counter | React Js word count in Textarea
React Word Counter | React Js word count in Textarea:To implement a word count feature in a textarea using React.js, you can start by creating a state variable to hold the textarea value. Then, attach an event listener to the textarea's onChange event, updating the state with the current value. Next, split the value by whitespace and use the length of the resulting array to calculate the word count. Finally, render the word count alongside the textarea. By dynamically updating the word count on every change, you provide real-time feedback to the user. This approach efficiently tracks and displays the word count in a React.js application.

How can I implement React Js word counter in a textarea?
This code snippet demonstrates a React.js component that counts the number of words entered in a textarea. It utilizes React hooks, specifically the useState hook, to manage the state of the entered text. The handleTextChange function updates the text state whenever the textarea content changes.
The getWordCount function calculates the word count by splitting the text using whitespace as a delimiter and filtering out empty strings. The result is displayed in the paragraph tag below the textarea.
