Given an array of items arr

const arr = [
    {type: 'phone', color: 'green', name: 'iPhone'},
    {type: 'phone', color: 'gold', name: 'Samsung'},
    {type: 'computer', color: 'silver', name: 'Chromebook'},
];

And rules

const rules = [
    {k: 'name', v: 'iPhone'},
    {k: 'color', v: 'gold'},
];

Filter the elements from the items array with rules from the rules array.

example output:

 [
    {type: 'computer', color: 'silver', name: 'Chromebook'},
]
