Uncaught ReferenceError: books is not defined

Write a function checkBasket() that lets you know if the item is in the basket or not.

Here is the object basket:

amazonBasket = {
 glasses: 1,
 books: 2,
 floss: 100
}

What I tried in my JS:

function checkBasket(basket, lookingFor) {
   for(item of amazonBasket)
   {
       if(lookingFor===item){
           console.log("This item is in the basket")
       }else{
           console.log("This item is not in the basket")
       }
})
}
checkBasket(amazonbasket, books)

i.e:

checkBasket(amazonbasket,books)

it will return “This item is in the basket”

I don’t understand why books are undefined.
