filter with condition and return specific things in javascript 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 of objects

function isBigEnough(value) {
  return value >= 10
}

let filtered = [12, 5, 8, 130, 44].filter(isBigEnough)
// filtered is [12, 130, 44]
