# Format.js
Format.js is a simple JavaScript format function, like a Java String.format.
It works in Chrome, Firefox, Safari, Opera, and IE 6.0+.
## Usage
### String
`%s`
var s = format('%s world.', 'Hello');
console.log(s); // 'Hello world.'
`%8s` (Left padding)
var s = format('%8s world.', 'Hello');
console.log(s); // ' Hello world.'
`%-8s` (Right padding)
var s = format('%-8s world.', 'Hello');
console.log(s); // 'Hello world.'
### Number
`%d`
var s = format('%d billion people.', 7.062);
console.log(s); // '7.062 billion people.'
`%5d` (Left padding)
var s = format('%5d billion people.', 7);
console.log(s); // ' 7 billion people.'
`%-5d` (Right padding)
var s = format('%-5d billion people.', 7);
console.log(s); // '7 billion people.'
`%03d` (Zero padding)
var s = format('%03d billion people.', 7);
console.log(s); // '007 billion people.'
`%o` (Octal notation)
var s = format('0%o', 100);
console.log(s); // '0144'
`%x` (Hex notation)
var s = format('0x%x', 255);
console.log(s); // '0xff'
### Escape
`%%d`
var s = format('%%d to %d', 100);
console.log(s); // '%d to 100'
