    Leading Zeros - 140byt.es

Pad a given number with leading zeroes. Useful to make it a fixed width like with e.g. sprintf in other programming langages.

Example: 00001, 00012, 00123, 01234, 12345

Usage

pad(number, count);
// returns number with leading zeros
For more information

See the 140byt.es site for a showcase of entries (built itself using 140-byte entries!), and follow @140bytes on Twitter. And check my "JavaScript Golf Lessons" slides.

  
## annotated.js
function(
  a, // the number to convert
  b // number of resulting characters
){
  return (
    [ 1e15 ] + a // combine with large number
  ).slice(-b) // cut leading "1"
}

## index.js
function(a,b){return([1e15]+a).slice(-b)}
