Answer 1

Anusi Chidera Paschal

This is Node JS

Use console.log instead of document.write

Answer 2

Thank you AJ I really appreciate

Answer 3

document.write() might work if your node.js code is inside a html file in a browser.
Instead of document.write() use

console.log()

if you need a new line or

process.stdout.write()

for printing in the same line.
