[Question] Array encapsulation functionality

In the middle of the process of making a Pokédex-like application, I saw that this library provides some kind of array encapsulation, allowing to make several requests with just one function call.

P.getBerryByName(['cheri', 'chesto', 5])
    .then((response) => {
      console.log(response);
    })

However, I want to know how the process is made in order to know if this would transform several requests to the API in just one concatenated.

The idea was to use this to implement a search component in the application since the other way consist in making one request to the general endpoint and a singler request per element of the results in the first request. As result, this could lead a decrement of the requests made to the API.

Thank you for all of this.
