Vector2

A TypeScript 2D vector math library.

Mutable and Immutable Data

For operations that change vector components, the Vector2 library
provides functional methods for working with immutable data as well as an interface for
working with mutable data.

Functional Methods

For working with immutable data, all of the top-level functions provided by the library
are purely functional and return new Vector2 objects.

``typescript
import { Vector2, add } from '@graph-ts/vector2';

const a: Vector2 = { x: 0, y: 1 };
const b: Vector2 = { x: 1, y: 0 };
const c: Vector2 = add(a, b);

console.log(c); // { x: 1, y: 1 }
`

Method chaining

To apply operations to a target vector, the Vector2 library requires you to be explicit
about your intentions. The update() method returns an object that contains chainable
vector updating methods.

`typescript
import { Vector2, update } from '@graph-ts/vector2';

const a: Vector2 = { x: 0, y: 1 };
const b: Vector2 = { x: 1, y: 0 };

update(a) // update vector a by...
.add(b) // adding vector b and...
.translate(0, 1); // translating a distance of 1 along the x-axis

console.log(a); // { x: 2, y: 1 }
