How to filter by several parameters?

I want the user base to be able to filter by several parameters.

I have an object with parameters to filter:

const options = { _id: 'fu4gosy5hjruierbweyuu5u6hh', name: "Jhon" }

and an array of objects with a database of users:

const base = [
    { _id: '5h245jg2h4gjh2jh5g2j4hg52g', name: 'Jhon' },
    { _id: 'fdgd6fgd7f84b5hhjfdghj4hgg', name: 'Jhon' },
    { _id: 'fu4gosy5hjruierbweyuu5u6hh', name: 'Jhon' }
]

Of course you could make everything much simpler, namely to filter by unique id, but you have to understand that filtering has to be by several parameters and parameters can be completely different.

I tried using every() in filter().

In your filter function you can loop through all the object properties:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const find = (data, query) => 
  data.filter(entry => {
    for(const [key, value] of Object.entries(query)) {
      if(entry[key] !== value) return false
    }
    return true
  })

const base = [{
    _id: '5h245jg2h4gjh2jh5g2j4hg52g',
    name: 'Jhon'
  },
  {
    _id: 'fdgd6fgd7f84b5hhjfdghj4hgg',
    name: 'Jhon'
  },
  {
    _id: 'fu4gosy5hjruierbweyuu5u6hh',
    name: 'Jhon'
  },
  {
    _id: 'fu4gosy5hjruierbweyuu5u6hh',
    name: 'Jhon',
    entry: 2 // the 'find' function only cares about the given options
  }
]

const options = {
  _id: 'fu4gosy5hjruierbweyuu5u6hh',
  name: "Jhon"
}
console.log(find(base, options))
console.log(find([
  { name: "apple", category: "fruit" },
  { name: "celery", category: "vegetable" },
  { name: "mushroom", category: "vegetable" },
  { name: "lemon", category: "fruit" },
  { name: "watermelon", category: "fruit" },
], { category: "fruit" }))

The filter function can be given greater versatility by being used in conjunction with a lambda. I'm not familiar with filter, but it seems filter places every iterated object into the function provided and breaks if you straightfowardly try to add more parameters to said function.

So this

function is_bigger_than(element, value) {
  return element > value
}

filter(is_bigger_than(10))

wouldn't work because the function provided executes before an object can even be placed into it for evaluation. That means a lambda, which won't run so soon, is needed.

It would look like this

filter((automatically_inserted_element) => is_bigger_than(element, value))

you can just then tweak with is_bigger_than to accept more parameters and whether it works on a "both" or "or" basis.

function is_bigger_than(element, value, start_value) {
  return (element > value && element.toString().slice(0, 1) == start_value)
}
