Mengurutkan Array Berdasarkan Nilai Boolean Di JavaScript

const items = [
	{ name: "Item A", featured: false },
	{ name: "Item B", featured: true },
	{ name: "Item C", featured: false },
	{ name: "Item D", featured: true },
];

// Urutkan featured: true dulu, lalu false
items.sort((a, b) => (a.featured === b.featured ? 0 : a.featured ? -1 : 1));

console.log(items);

Penjelasan singkat:

• (a.featured === b.featured) ? 0 → kalau sama, urutan tidak berubah.
• a.featured ? -1 : 1 → kalau a.featured itu true, maka a akan ditempatkan sebelum b.

Hasil:

[
	{ name: "Item B", featured: true },
	{ name: "Item D", featured: true },
	{ name: "Item A", featured: false },
	{ name: "Item C", featured: false },
];

Kalau mau false dulu baru true, tinggal balik urutannya jadi:

items.sort((a, b) => (a.featured === b.featured ? 0 : a.featured ? 1 : -1));
