(ns live.test
(:require [cljs.test :refer-macros [deftest is run-tests]]))
(defn dot-product [a b]
(reduce +
(map * a b)))
(deftest dot-product-test
(is (= 0 (dot-product [0 1 0] [1 0 0])))
(is (= 3 (dot-product [1 1 1] [1 1 1])))
(is (= 32 (dot-product [1 2 3] [4 5 6])))
(is (= 256 (dot-product [2 5 6] [100 10 1]))))
