How does readline-sync.keyInYN work?

readline-sync.keyInYN() is a function in the readline-sync package that prompts the user to enter a "yes" or "no" answer by pressing "Y" or "N" on the keyboard and returns true if the user enters "Y" and false if the user enters "N". It also allows for customization of the message prompt and default value.

const readlineSync = require("readline-sync");

const answer = readlineSync.keyInYN("Do you want to proceed?");

if (answer) {
  console.log("Great, let's proceed!");
} else {
  console.log("Okay, maybe some other time.");
}

In this example, the keyInYN() method is called with a string argument that will be displayed to the user as the question to answer. The user can input "y" for "yes" or "n" for "no". The function returns true if the user answered "y" and false if the user answered "n".
