Homework one - Vector Library.

Vector Library:

A JavaScript library for 2D vectors.

Installation

You can install the library using npm:

npm i homework-vector-library

code is in /src/

Usage

Adding vectors

const sum = a.add(b);

Calculating vector length

const abs = sum.abs();

console.log(a.toString()); // Output: Vector(1, 2)

console.log(b.toString()); // Output: Vector(2, 0.5)

console.log(sum.toString()); // Output: Vector(3, 2.5)

console.log(abs); // Output: 3.905124837953327

Finding unit vector

const unitA = a.unit();

console.log(unitA.toString()); // Output: Vector(0.4472135954999579, 0.8944271909999159)

Calculating direction angle

const angleA = a.angle();

console.log(angleA); // Output: 1.1071487177940904 (in radians)
