tesseract-ocrHow do I create a Tesseract OCR JavaScript demo?

To create a Tesseract OCR JavaScript demo, you will need to install the Tesseract OCR library and its dependencies.

First, install the Tesseract OCR library using npm: npm install tesseract.js.

Then, create a JavaScript file with the following code:

const Tesseract = require('tesseract.js')

Tesseract.recognize('image.png')
    .then(function(result){
        console.log(result.text);
    })

This code will use the Tesseract library to recognize the text in the image 'image.png'.

Next, create an HTML file with the following code:

<!DOCTYPE html>
<html>
<head>
    <title>Tesseract OCR Demo</title>
</head>
<body>
    <h1>Tesseract OCR Demo</h1>
    <p>
        This is a demo of the Tesseract OCR library.
    </p>

    <script src="script.js"></script>
</body>
</html>

This code will create an HTML page with a heading and a paragraph.

Finally, open the HTML page in a web browser and open the JavaScript console. The result of the Tesseract OCR recognition should be printed in the console.
