A comprehensive TypeScript vector math library providing 2D, 3D, and 4D vector operations with a focus on performance and type safety.

/**
 * Creates an ArrayVector2D from y-axis angle.
 * @param {number} phi - Angle in radians
 * @param {number} magnitude - Optional magnitude of the vector (default: `1`)
 * @returns {ArrayVector2D} Vector
 */
export const fromAngleY2D = (phi, magnitude = 1) => [
    magnitude * -Math.sin(phi),
    magnitude * Math.cos(phi),
];
