But... who can use sancronos-validator?

Answer: Everyone!

For Promise lovers

const sancronos = require("sancronos-validator");
//..
sancronos.isValid("* * * * *")
.then(function(crontab) {
  //.. do something
})
.catch(function(err) {
  // handle error
});

For callback lovers

const sancronos = require("sancronos-validator");
//..
sancronos.isValid("* * * * *", (err, crontab) => {
  if(err){
    //Oops I did it again!
  }
  //Do something with your newly validated crontab
});

For sync lovers

const sancronos = require("sancronos-validator");
//..
let crontab = sancronos.isValid("* * * * *", true);
//Do something with your crontab
//Be aware that in case it's invalid, it will throw an error.

See test/ for more details.
