Tell us what’s happening:

I’m trying to check equality with the id property of the function and the id property of item but it’s telling me that I’m doing something wrong. I don’t know what.

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

  addItem(id, products) {
    const product = products.find((item) => item.id === id.addItem)
  }

// User Editable Region

returns whether the id property of item is strictly equal to the id

What do you mean by id.addItem?

I’ve just been playing around with ways of identifying the parameter that’s supposed to be measured. addItem.id hasn’t been working.

addItem is a method, id is one of its parameters.

Inside find compare item.id to the id parameter.

Example 
const users = [
  { id: 1, name: "John", age: 34 },
  { id: 2, name: "Amy", age: 20 },
];

const findUser = (id, users) => users.find((user) => user.id === id);

const user1 = findUser(1, users);
console.log(user1); // { id: 1, name: 'John', age: 34 }

const user2 = findUser(2, users);
console.log(user2); // { id: 2, name: 'Amy', age: 20 }
