How to filter an array using another array in Javascript?

August 3, 2022

I have an array of objects that has "number" property in it, i want to filter this array based on the "number" property through an array of numbers called "filteredNumbersArray"

i tried this but it doesn’t make any changes to the array

const remaining = phones.filter(
          (data) => !((data.number as number) in filteredNumbersArray),
        );

const remaining is the filtered phones array.

phones is my array of object, my object has a field number: number

example on data in phones: [{number: 5}, {number:2}]

filteredNumbersArray is an array of numbers. ex.[1,2,3]

i want result to be [{number:5}] based on the above example.

>Solution :

you could use array.includes to know if it contain an element

const phones = [{number: 5}, {number:2}] ;
const filteredNumbersArray = [2,4,6];
console.log( phones.filter( e => !filteredNumbersArray.includes(e.number) ) );
