Wacktor

Solves the main pain points I have with the other vector libraries:

• vectors are not being mutated => every method returns a new vector
• methods accept vectors, objects, arrays and single numbers

var Vector = require('Wacktor');
var v1 = new Vector(2, 3);
var v2 = new Vector([4, 2]);
var v2 = new Vector({x: 13, y: 37);

Methods

Iterable

var v1 = new Vector(2, 3);
console.log(...v1); // 2, 3
var [x, y] = v1;
console.log(x);     // 2

add, sub, mul

The method signature is the same for each of these.

(Number n)

n will be applied to x & y

(Number nx, Number ny) OR ([Number nx, Number ny])

nx will be applied to x, ny to y

(Vector/Object v)

x of v will be applied to x, y of v to y

v1.add(2);      // (4, 5)
v1.add(2, 0);   // (4, 3)
v1.mul([2, 5]); // (4, 15)

magSq, mag

Returns the (squared) magnitude.

new Vector(4, 3).mag(); // 5

neg

new Vector(12, 34).neg(); // (-12, -34)

equals

Compares the vector with another vector, numbers, array or object.

dist

Distance to another vector, numbers, array or object

dot

angle

max
