By default inquirer js questions are preceded by a '?'. Is it possible to change it to something else? I tried exploring but did not find it mentioned anywhere.
Sure, you can change the prefix of your question with the prefix option of your question object:
inquirer
.prompt({
type: 'input',
prefix: '$',
name: 'first_name',
message: 'What\'s your first name'
})
// => $ What's your first name
