splice
const loyaltyPrograms = [{ id: 1 }, { id: 2 }, { id: 3 }, { id: 4 }, { id: 5 }]; let id = 3; const loyaltyProgramIndex = loyaltyPrograms.findIndex((item) => item.id === id); if (loyaltyProgramIndex === -1) { return; } // replace existing object with new one loyaltyPrograms.splice(loyaltyProgramIndex, 1);
filter
let loyaltyPrograms = [{ id: 1 }, { id: 2 }, { id: 3 }, { id: 4 }, { id: 5 }]; let id = 3; loyaltyPrograms = loyaltyPrograms.filter((item) => item.id !== id);
