Please check this example https://onecompiler.com/javascript/3y5prbmjv
In JavaScript, you can access stdin (standard input) using the process.stdin object.
Here is a simple example that reads a line of input from the user and then prints it back to the console:
const readline = require('readline').createInterface({
input: process.stdin,
output: process.stdout
});
readline.question('Enter a line of text: ', (input) => {
console.log(`You entered: ${input}`);
readline.close();
});
In this example, we are using the readline module, which provides an easy way to read input from the user. The createInterface method creates a new readline.Interface object, which takes an input stream (process.stdin) and an output stream (process.stdout).
The question method of the readline.Interface object takes two arguments: a prompt message to display to the user, and a callback function that will be called with the user's input when they press Enter. The close method is called to close the readline.Interface object once we are done reading input.
Note that process.stdin is a readable stream, which means you can also use the data event to read input from the user. Here's an example that does that:
process.stdin.setEncoding('utf8');
process.stdin.on('data', (chunk) => {
console.log(`You entered: ${chunk}`);
});
In this example, we set the encoding of the stdin stream to utf8 so that we can read string input from the user. Then, we listen for the data event on the stdin stream, which is emitted whenever the user enters input. The chunk argument passed to the event listener contains the user's input.
