JavaScript array includes multiple values

  • by

The includes() method in JavaScript only checks for the presence of a single value in an array. If you want to check for the presence of multiple values in an array, you can use the every() method in combination with the includes() method.

Simple example code.

<!DOCTYPE html>
        const array = [1, 2, 3, 4, 5];
        const valuesToCheck = [5, 4];

JavaScript array includes multiple values

Another way to check if an array contains multiple values in JavaScript.

The every() method is used in combination with the indexOf() method to check if every element in array_a is present in array_b.

const array_a = [1, 2, 3];
const array_b = [3, 2, 1];

const success = array_a.every(function(val) {
    return array_b.indexOf(val) !== -1;

console.log(success); // true
