Creating your own filter method equivalent

Implement the function myFilter, which will work the same way as the built-in Array.prototype.filter. After adding it to an array, calling myFilter should return the same result as the original filter.

const source = [1, 2, 3, 4, 5, 6];

const expected = source.filter(item => item % 2);

const actual = source.myFilter(item => item % 2);

console.log(expected);
// console.log(actual);
