const validate = require("aproba")

const myfunc = (...args) {
  validate('SNF', args)
}

myfunc('test', 23, function () {}) // ok
myfunc(123, 23, function () {}) // type error
myfunc('test', 23) // missing arg error
myfunc('test', 23, function () {}, true) // too many args error

Valid types are:

Validation failures throw one of the following code errors:

• EMISSINGARG
• EINVALIDTYPE
• ETOOMANYARGS
• EUNKNOWNTYPE (for an invalid type)

P.S: For optinal args one can use a | ex: SO|S.
