Handling multliple readlines for my CLI application.

I'm working on a little CLI project which uses the readline module.The problem is that I have a top level readline.question which holds a switch to cases that can trigger other readline.question (s). The result is that I can pass the first readline.question, trigger the other readline.question, but can't escape back up to the top level.So in a diagram: 1st readline > answer > 2nd readline > answer > nothing.Whereby I would like a sort of recursion that takes me back to the first readline.The code is as follows:const actionPoint = () => { readline.question('Action:', (action) => { switch (action) { case '0': presentEmailRegistrationScreen(readline) break; case '1': fieldEmailRemovalOption(readline) break; case '2': listEmails() break; case 'E' || 'e': console.log(chalk.red('Exiting application.')) return readline.close() default: console.log(chalk.red('Command not recognised.')) break; } return actionPoint() }) } And as a case, presentEmailRegistrationScreen returns the following:const askRecursively = (readline) => { readline.question('Enter your email: ', (email) => { if (validator.validate(email)) { console.log(chalk.green(`New email: ${email} is valid`)) if (!duplicateEmails(email)) { if (writeEmailToFile(email)) { console.log(chalk.green('Email registered.')) readline.close() return true } } else { console.log(chalk.bgRed('Unable to register email.')) return askRecursively(readline) } } else { console.log('\n') console.log(chalk.red('The email: '), chalk.bgRed(email), chalk.red(' is not valid.')) return askRecursively(readline) } }) } Ignoring the shoddiness of my code (to a point) how would you suggest I lay out my code to ensure that when I reach return true here, I return back up to the first readline?
