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

/**
 * Calculates the squared Euclidean distance between two 3D vectors.
 * @param {ArrayVector3D} xyz1 - First vector as `[x, y, z]`
 * @param {ArrayVector3D} xyz2 - Second vector as `[x, y, z]`
 * @returns {number} Squared Euclidian distance
 */
export const distanceSq3D = (xyz1, xyz2) => (xyz1[0] - xyz2[0]) ** 2 + (xyz1[1] - xyz2[1]) ** 2 + (xyz1[2] - xyz2[2]) ** 2;
