    async function readFile(file) {
    const text = await file.text();
    console.log(text); // Will output: "my name is x"
    return text;
}

// Usage
fileInput.addEventListener('change', async (e) => {
    const text = await readFile(e.target.files[0]);
    // Use your text here
});

    Yes, you can easily achieve this using the FileReader API in JavaScript. Here’s a simple example to read the contents of a .txt file and store it as a string:
    HTML and JavaScript Code

    <!DOCTYPE html>
<html>
<head>
    <title>Read Text File</title>
</head>
<body>
    <h1>Upload a Text File</h1>
    <input type="file" id="fileInput" accept=".txt" />
    <p id="fileContent"></p>

    <script>
        document.getElementById("fileInput").addEventListener("change", function(event) {
            const file = event.target.files[0]; // Get the uploaded file
            if (file) {
                const reader = new FileReader(); // Create a FileReader object
                
                reader.onload = function(e) {
                    const fileContent = e.target.result; // Get the file content as a string
                    console.log(fileContent); // Output the content to console
                    document.getElementById("fileContent").innerText = fileContent; // Display content
                };

                reader.readAsText(file); // Read the file as a text
            } else {
                alert("No file selected.");
            }
        });
    </script>
</body>
</html>

    const fs = require('fs');
  fs.readFile('Input.txt', (err, data) => {
  const result = data.toString();
  console.log(result);
});

    Simplest way!
