const zeroPad = require('zero-pad');

console.log(zeroPad(7)); // 07
console.log(zeroPad(9)); // 09

console.log(zeroPad(0.1)); // 0.1

// With an array as argument
const arr = zeroPad([1, 10, 7]);
console.log(arr); // [01, 10, 07]

// Example with dates
const date = new Date(2016, 10, 5);

  date.getFullYear(),
  date.getMonth(),
  date.getDate()
]);

console.log(pad.join('-')); // 2016-10-05
