javascript array.filter multiple arguments code example

Example 1: filter out object in array using two arguments

var arr= [{id: "123", name: "Faa"},
          {id: "123", name: "Bar"},
          {id: "345", name: "Foo"},
          {id: "678", name: "FaaBar"}
         ];

var name = 'FaaBar';
var id = '678';

arr = arr.filter(function(elem) {
  //return false for the element that matches both the name and the id
  return !(elem.id == id && elem.name == name)
});

Example 2: javascript filter array multiple values

// use .filter and write multiple validations in the callback function

let numbers = [3, 7, 2, 15, 4, 9, 21, 14];

let filteredNumbers = numbers.filter(function (currentElement) {
  if (currentElement > 3 && currentElement < 17) {
    return true;
  }
});

console.log(filteredNumbers);
