directionality

Determines the writing system's directionality based on characters tests.

Installation

$ component install component/directionality

Example

var dir = require('directionality');
dir('الولايات المتحدة الأمريكية'); // 'rtl'
dir('Hello world'); // 'ltr'

Methodology

The decision is made based on the first character of the input string, testing for a range of unicode characters that belong to rtl or ltr languages (see API to learn how to access the regular expressions).
