API

`cosSimilarity(vectorA, vectorB)`

Returns the cosine similarity between the given vectorA and vectorB. Returns 0 when given a zero vector, [], undefined or nothing.

import cosSimilarity from "cos-similarity";

cosSimilarity([1, 2, 4], [1, 0, 2]); // -> 0.8783100656536799
cosSimilarity([1, 2, 0], [1, 2, 0]); // -> 1
cosSimilarity([2, 0, 0], [0, 2, 0]); // -> 0
cosSimilarity([-1, -2, 0], [1, 2, 0]); // -> -1
