Not a kata issue. Your code does not throw an Exception when query is not an array of Object

Your code does not throw an error / exception when any of the given inner array of the 2-dimensional array is not of length 2. One of such cases being:

[
1, 2, 3, 4,
5, 6, 7
]

This is the design of the kata, there is only 1 exception to throw though, and the conditions of each are specified. This is a much better kata design than a lot of those which prompt users to return -1 / return "invalid string" as returning multiple types is bad practice.

The only thing that one might be nitpicking is different condition should throw different Exceptions for debugging purposes . But since this is not a production-based coding foundation, I do not see much of an issue :-)

Easy and cool Kata, BUT WHY SO MANY EXCEPTIONS??????? Are you kiding me??????

Query length should not be less than or greater than 2. If it is, throw error.

Добрый день!
Условия у данной Ката не отражают суть задачи.
Поэтому решил написать данное пояснение, возможно кому-то поможет не ломать голову.

1. На самом деле описание следующее:
   У вас есть гипотенуза и катет в прямоугольном треугольнике.

• est - оцениваемое расстояние от полицейского до дороги (катет в треугольнике) - 1 расчет
• act - фактическое расстояние от полицейского до дороги (катет в треугольнике) - 2 расчет
  readings - содержит 4ре значения.
  const [[distance1, time1], [distance2, time2]] = readings;
• distance1 - дистанция от радара до автомобиля (1 замер)
• time1 - время (1 замер)
• distance2 - дистанция от радара до автомобиля (2 замер)
• time2 - время (2 замер)
• timeDif - (time1 - time) - не может быть отрицательным значением (используется для расчета обоих расстояний
  Есть два подхода, чтобы учесть данное условие:
  Обратите внимание, что ваш код должен быть способен обрабатывать показания, передаваемые в функцию в любом порядке.
  Можно вернуть модуль числа при расчетах или просто изменить порядок элементов массива (distance1 > distance2)

На всякий случай формула прямоугольного треугольника: (A2 + B2 === C**2) (A/B - катеты) (C - гипотенуза)
Только нужно не забывать, что нам нужно относительное значение и в километрах в час.

Good day!
The conditions of this Kata do not reflect the essence of the problem.
Therefore, I decided to write this explanation, perhaps someone will help not to break his head.

1. Actually the description is as follows:
   You have a hypotenuse and a cathetus in a right triangle.

• est - estimated distance from the policeman to the road (the cathetus in the triangle) - 1 calculation
• act - actual distance from the policeman to the road (the cathetus in the triangle) - 2 calculations.
  readings - contains 4 values.
  const [[distance1, time1], [distance2, time2]] = readings;
• distance1 - distance from the radar to the car (1 measurement)
• time1 - time (1 measurement)
• distance2 - distance from radar to car (2nd measurement)
• time2 - time (2nd measurement)
• timeDif - (time1 - time) - cannot be a negative value (used to calculate both distances).
  There are two approaches to account for this condition:
  Note that your code must be able to handle readings passed to the function in any order.
  You can return the modulus of the number in the calculation, or you can simply change the order of the array elements (distance1 > distance2)

Just in case, the formula for a right triangle: (A2 + B2 === C**2) (A/B - cathetes) (C - hypotenuse).
Only we need to remember that we need a relative value and in kilometers per hour.

P.S. please explain in the problem that you have an angle to the road of 90 degrees (For est and act this is a very good explanation).

1. Bump. Completely broken tests.
2. Extremely cryptic description.
3. Worst kata experience ever (after solving 6500 ones...)

Solved...

I seem to be getting funny errors despite having solved this questions, any tips please?

Hello, I'm stuck on the solution of this Kata.
Basically I've solved, just I don't understand what kind of error this Kata expects from:
I used // throw new Error(""); but it seems to not be the solution expected by the author so any tips/ suggestion would be helpful

cheers

Awesome Kata! Thanks!
