Add leading zeros to fill a certain number to the given size.
npm install zeroise
About
This will fill a number with leading zeros to reach a specified digit threshold.
If you set the threshold to '4' and the number is '17', then you will get back '0017'.
If you set the threshold to '4' and the number is '1400', then you will get back '1400'.
Optionally, you can specify your preferred string to pad the number with (instead of the default '0').
Syntax
zeroise(12, 5, 0);
number

Usage

var zeroise = require('zeroise');
var result = zeroise(12, 4);
console.log(result); // 0012
