Dark_Knight :
I am new to Javascript so forgive me if my query is too trivial. I am writing a simple program using the function "confirm()". Here it is:
if (confirm("Are you xyz?"))
{
console.log("Hello xyz, how are you?");
} else {
console.log("Then what is your name?");
}
But on running this I get the error: confirm is not defined. Do I need to install or call a package to make this confirm() function defined?
Aplet123 :
There's a very important difference between browser javascript and node.js. Browsers have a confirm function, while node does not. If you want to do something similar, you can use the readline module.
const readline = require("readline");
const interface = readline.createInterface({
input: process.stdin,
output: process.stdout
});
interface.question("Are you xyz? (y/n) ", function(ans) {
if (ans == "y" || ans == "yes") {
console.log("Hello there xyz.");
} else {
console.log("So what is your name?");
}
// pause the interface so the program can exit
interface.pause();
});
