Write a JavaScript program to create the dot products of two given 3D vectors

function dot_product(vector1, vector2) {
  var result = 0;
  for (var i = 0; i < 3; i++) {
    result += vector1[i] * vector2[i];
  }
  return result;
}
console.log(dot_product([1,2,3], [1,2,3]))
console.log(dot_product([2,4,6], [2,4,6]))
console.log(dot_product([1,1,1], [0,1,-1]))
