Passing functions as an argument, how to use the same passed object, passed along with these functions in them?

Question

JavaScript

How can I use the same people object in both the query function and the select and filterIn functions?

var lib = {
    query: query,
    select: select,
    filterIn: filterIn
};

function query(collection) {
    //Сюда получаем
}

function select() {
    // Как использовать тот же или копию collection что мы получили в query в этой функции?
}

function filterIn(property, values) {
    // Как использовать тот же или копию collection что мы получили в query в этой функции?
}

var people = [
    {
        name: 'Андрей',
        gender: 'Мужской',
        email: '[email protected]',
    },
    {
        name: 'Николай',
        gender: 'Мужской',
        email: '[email protected]',
    }
]

var result = lib.query(
    people,
    lib.select('name', 'gender'),
    lib.filterIn('name', ['Андрей', 'Николай'])
);

Answer 1

Write one common function, pass an object into it, and use these functions inside and it is desirable to declare them as: '_query()', '_select()', etc. Add '_' in general. This designation is used if you need to show that these functions are needed only inside the object / class and outside it you do not need to use them
