JavaScript console input and store as a variable.
I have created a JavaScript console input code and tried to return the value but it showed "undefined" //Here's what I've tried var a = input(); function input(){ process.stdin.resume(); process.stdin.setEncoding("ascii"); process.stdin.on("data", function(value){ return value; }); }

Ok. Then here is an example of input in Node.js from the console.
const readline = require('readline);
const userInput = readline.createInterface({
input: process.stdin,
output: process.stdout
});
userInput.question('What is your favorite number? ', (favNum) => {
let num = favNum;
console.log(`Thank you, your favorite number is: ${favNum}`);
userInput.close();
});
On a windows 10 machine in the cmd type node enter, then type .editor enter and when finished writing the code type ctrl + d. It will ask what is your favorite number. But, because you are typing input from the same cmd it shows each digit twice but, gives the correct output.

If you tried this on Sololearn..... Unfortunately it's not gonna work
if not, for input as far as I know we use :
let variable = console.readline();

Subhajeet Sikdar ... In JavaScript input is obtained with the prompt() function. Here is an example using HTML and a function that uses the document.get ElementBy Id().innerHTML Dom function.
<!DOCTYPE html>
<html>
<body>
<!--A Simple JS Function: Declararion, Invocation and Return that will call a function which prompts user input then performs a calculation and returns the result.-->
<p id="demo"></p>
<script>
var _$x = myFunction();
document.getElementById("demo").innerHTML = _$x;
function myFunction(a) {
a = prompt("Enter a number to find its Squareroot");
let b = Math.sqrt(a) ;
return "The squareroot of the number you entered is " + b;
}
</script>
</body>
</html>
