What is the `filter` method in JavaScript?

Description : `filter` creates a new array with elements that pass a specific test.

Answer :

The `filter` method is a higher-order function in JavaScript that creates a new array containing all elements of the original array that pass a test implemented by a provided function. The function is called for each element in the array, and if it returns `true`, the element is included in the new array. The original array is not modified. 

const numbers = [1, 2, 3, 4];
const evenNumbers = numbers.filter(n => n % 2 === 0);
console.log(evenNumbers); // [2, 4]
