JavaScript Vector Classes for Creative Coding

I have started a small collection of JavaScript Euclidean Vector classes. These are commonly used in creative programming. I wanted a quick way of adding Vectors in to any project that may need them so they’re installable from bower and have a basic set of methods available.

Set up

Currently there is 2 dimensional and 3 dimensional Vectors available. Add references to the files to your project.


You can install these as a bower dependency

$ bower install js-vector-classes --save


This can be used as a RequireJs dependency. The Vector files will return the JavaScript constructor class. You will just need to point the module name to the corrent location of each file.

require(['Vec2'], function(Vec2){
    var velocity = new Vec2(10, 5);


You can start using this vector by creating a new instance:

var v        = new Vec2(1, 5),
    velocity = new Vec2(10, 5),
    location = new Vec2(250, 100)

You can set the properties again using

v.set(x, y)


You have the following methods available to you.

// Maths
v.mult(Vec2) // multiply
v.div(Vec2)  // divide
v.mod(Vec2)  // modulus

// helpers
v.inv()      // invert

New Instances

Each of these also have a version which returns a new instance just change the first letter to be uppercase.

// => etc


You also have a few helper functions


This copies the properties of another vector in to the current vector.


This returns a new instance of the current vector with cloned values


This will return true if the properties of the two vectors are equal


This will return the distance between two vectors.
