To display the count of words, the Word count is used. First, we must initialize the total number of words in the box. Based on this, we must write the sentence. The sentence will stop after the point. We use the first handle, the handle submits, and the second handle. Limwords will give us limited words. If we type extra words, the error will be shown like 'you exceeded the maximum no of words'.If we type fewer words, the hint will be 'you still have to write (result) words'. 

The number of words and characters (including whitespace) will be displayed when you type some text into this text area. When the user types something into the text area using the input event handler on the text area, the countWord() function is called every time.  

While you are typing a word, count the number of words in a document. This also counts pages, paragraphs, lines, and characters. This method is used when you need to know how many words, pages, characters, paragraphs, or lines are in a document. Suppose the loop is used to check the status of the word count. This method satisfies our conditions to fill the text in the text area as required.  

  • In real-time, the Word Counter is a tool for counting words, characters, sentences, and paragraphs, while you type.  
  • This method calculates the reading time of your text. 
  • Its readability score helps improve the content of your website, essay, or document. 

Here is an example of how to create a word counter using Reactjs: 

Preview of the output that you will get on running this code from your IDE.


In this solution we use the React library.

   class App extends React.Component {
  constructor(props) {
    this.state = {
      firstValue: "",
      secondValue: "",
      needWords: "",
      wordCount: "",
      limWords: null
    this.firstHandle = this.firstHandle.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
    this.secondHandle = this.secondHandle.bind(this);
  firstHandle(e) {
      firstValue: e.target.value

  handleSubmit(e) {
      needWords: this.state.firstValue,
      secondValue: ""

  secondHandle(event) {
    //calculate the word count first itself and use them in other manipulations
    const wordCount =
      event.target.value === "" ? 0 : event.target.value.split(" ").length;
      secondValue: event.target.value,
      wordCount: wordCount,
        this.state.needWords - wordCount < 0
          ? this.state.secondValue.length
          : null

  render() {
    var result = this.state.needWords - this.state.wordCount;
    let tooManyChars;
    if (result < 0) {
      const tooManyCharStyle = {
        color: "red"
      tooManyChars = (
        <p style={tooManyCharStyle}>
          You exceeded the maximum number of words!!
    return (
        <form onSubmit={this.handleSubmit}>
          <p>How many words do you have to write?</p>
          <button type="submit">Go</button>
          <p>You still have to write {result} words</p>


Follow the steps carefully to get the output easily.

  1. Install the Node.js and React on your IDE(preferable Visual Studio Code).
  2. Create React Application using npx create-react-app foldername.
  3. cd foldername.
  4. Open the folder in IDE.
  5. Copy the code using "copy" button above and paste it in App.js file(remove the earlier code from App.js).
  6. Import React and React-Dom.
  7. Add const rootElement = document.getElementById("root"),ReactDOM.render(<App />, rootElement),export default App to the end of the line.
  8. Open the terminal from IDE.
  9. npm start to run the file.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.

I found this code snippet by searching for Word Counter with React in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in VS Code 1.73.1 version.
  2. The solution is tested on Nodejs 16.14.2 version.
  3. react 18.2.0 version.

Using this solution, we are able to do Word Counter with React with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to do Word Counter with React.
