NPM info

letters

Iterate through sequences that include letters.

Installation

npm install --save letters

Usage

var Letters = require('letters');
var letters = new Letters(/*options*/)
 
console.log(letters.next()); // "a"
console.log(letters.next()); // "b"
// . . .
console.log(letters.next()); // "z"
console.log(letters.next()); // "aa"

Options

Some things are configurable via the options object.

useNumbers

Include numbers in the sequence (default is false). By default, when this option is provided, numbers are included after the letters.

var Letters = require('letters');
var letters = new Letters({ useNumbers: true })
 
console.log(letters.next()); // "a"
console.log(letters.next()); // "b"
// . . .
console.log(letters.next()); // "z"
console.log(letters.next()); // "0"

numbersFirst

Include numbers and place them before letters. useNumbers is implied by specifying this option, so you don't need both.

var Letters = require('letters');
var letters = new Letters({ numbersFirst: true })
 
console.log(letters.next()); // "0"
console.log(letters.next()); // "1"
// . . .
console.log(letters.next()); // "9"
console.log(letters.next()); // "a"
// . . .
console.log(letters.next()); // "z"
console.log(letters.next()); // "00"

startAt

By default, the sequence begins with the first character ("a" normally, or "0" with numbersFirst), but you can force the sequence to begin at any point, even at a multi-letter sequence.

var Letters = require('letters');
var letters = new Letters({ startAt: 'abc' })
 
console.log(letters.next()); // "abc"
console.log(letters.next()); // "abd"
