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);

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

The method signature is the same for each of these.

n will be applied to x & y

nx will be applied to x, ny to y

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)

Returns the (squared) magnitude.

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

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

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

Distance to another vector, numbers, array or object
