Filter multidimensional JSON array in vanilla JavaScript?

Question

JavaScript

Good time!
There is such an array that arrives from the backend via the REST API (tourist industry):

[
  {
    "id": 1,
    "resort": "Сочи",
    "hotels": [
      [4, 100, 8100],
      [3, 80, 5399],
      [5, 20, 15399],
      [4, 180, 8399],
    ]
  },
  {
    "id": 2,
    "resort": "Пхукет",
    "hotels": [
      [1, 30, 10570],
      [3, 50, 12799],
    ]
  },
  
  // ...ещё около 50 стран...

]

The element hotelscontains hotels of this resort with information (let's take the first one as an example):

...
      [ 
        4,  // кол-во звёзд отеля
        100,  // кол-во номеров
        8100 // средняя стоимость номера
      ],
...

So here's how to get this most average room rate (the third element of each hotel), if only known:

• Resort ID
  
• hotel stars
  
• number of rooms
  

For example:

I want to get the room rate in the Sochi resort, a 4 star hotel, where the number of rooms is 100.

Thanks in advance.
I will be glad to sensible comments!
