Array.prototype.filter

by Pawan Kumar @jsartisan

Implement a custom arrayFilter function that mimics the behavior of the native filter method.

Arguments

The arrayFilter function should take an array and a callback function as arguments. The callback function should be invoked with three arguments: the current element, the index of the current element, and the array itself.

Return Value

The arrayFilter function should return a new array containing all the elements for which the callback function returns a truthy value.

Use the following example to understand how the arrayFilter function should work:

const arrayFilter = (array, callback) => {
  // Your implementation here
};

const isEven = (num) => num % 2 === 0;

const numbers = [1, 2, 3, 4, 5, 6];
const evenNumbers = arrayFilter(numbers, isEven);

console.log(evenNumbers);
// Output: [2, 4, 6]
