vector

Vector object for canvas etc.

Installation

$ component install component/vector

Example

var Vector = require('vector');
var a = new Vector(5, 5);
var b = new Vector(10, 10);
a.distance(b);

or without new:

var vec = require('vector');
var a = vec(5, 5);
var b = vec(10, 10);
a.distance(b);
