How do I create a filter function javascript

Question

Does someone know how to write this code? On clicking the button, create a new table from people table, which will only contain people whose age is greater than 18 . Display the resulting array in the console

 const people = [
        {
            firstname: "Dreddy",
            lastname: "Nussgen",
            age: 70,
        },
        {
            firstname: "Yves",
            lastname: "Sear",
            age: 49,
        },
        {
            firstname: "Marcel",
            lastname: "Cowderay",
            age: 59,
        },
        {
            firstname: "Dag",
            lastname: "Binnall",
            age: 31,
        },
        {
            firstname: "Horten",
            lastname: "Claesens",
            age: 75,
        },
        {
            firstname: "Charmian",
            lastname: "Harnes",
            age: 10,
        },
        {
            firstname: "Sean",
            lastname: "Littlejohns",
            age: 37,
        },
        {
            firstname: "Hazlett",
            lastname: "Sprouls",
            age: 87,
        },

You can use `Array.prototype.filter()` – Yosvel Quintero May 31 '22 at 09:26 — Yosvel Quintero, May 31 '22 at 09:26

You can use Array.prototype.filter() combined with Destructuring assignment

Code:

const people = [{firstname: 'Dreddy',lastname: 'Nussgen',age: 70,},{firstname: 'Yves',lastname: 'Sear',age: 49,},{firstname: 'Marcel',lastname: 'Cowderay',age: 59,},{firstname: 'Dag',lastname: 'Binnall',age: 31,},{firstname: 'Horten',lastname: 'Claesens',age: 75,},{firstname: 'Charmian',lastname: 'Harnes',age: 10,},{firstname: 'Sean',lastname: 'Littlejohns',age: 37,},{firstname: 'Hazlett',lastname: 'Sprouls',age: 87,},{firstname: 'Marcel',lastname: 'Hasted',age: 66,},{firstname: 'Cary',lastname: 'Summerson',age: 15,},{firstname: 'Feodor',lastname: 'Ollett',age: 56,},{firstname: 'Kelly',lastname: 'Ranahan',age: 62,},{firstname: 'Madelene',lastname: 'Davie',age: 14,},{firstname: 'Bent',lastname: 'Karpe',age: 82,},{firstname: 'Reinaldo',lastname: 'Grimbleby',age: 81,},]

const result = people.filter(({ age }) => age > 18)

console.log(result)
