get index of matched element between two array of objects in javascript

I have two array of objects. I want to get the index of matched element from array 2. How to find that?

This is an example.

Array 1

selectedProduct: [{id:2, name:"product 1", category:"home"}]

Array 2

allProducts: [{id:1, name:"product 3", category:"grocery"},
             {id:2, name:"product 1", category:"home"},{id:3, name:"product 4",category:"vegetables"}]

Code snippet:

const index = this.allProducts.findIndex(item => this.selectedproduct.filter(entry => entry.id === item.id))

But, it is returning 0. How can i get the index of matched element?

Use some instead:

let selectedProduct = [
  {id:2, name:"product 1", category:"home"}
];
let allProducts = [
  {id:1, name:"product 3", category:"grocery"},
  {id:2, name:"product 1", category:"home"},
  {id:3, name:"product 4",category:"vegetables"}
]

const index = allProducts.findIndex(item => selectedProduct.some(entry => entry.id === item.id));

console.log(index);
