const menu = [{
       name: "tofu fritters",
       ingredients: ["tofu", "egg yolk", "breadbrumbs", "paprika"],
     },
     {
       name: "black bean curry",
       ingredients: ["black beans", "garam masala", "rice"],
     },
     {
       name: "chocolate tiffin",
       ingredients: [
         "dark chocolate",
         "egg",
         "flour",
         "brown sugar",
         "vanilla essence",
       ],
     },
     {
       name: "hummus",
       ingredients: ["chickpeas", "tahini", "lemon", "garlic", "salt"],
     },
   ];

searchResult = menu.some(menuItem => menuItem.ingredients === 'flour');
console.log(searchResult);

I was expecting this to return true since flour is present in the array for the third menu item but it returns false. Some() only seems to return true if I remove the array entirely from the object.

>Solution :

As menuItem.ingredients is an array, try with menuItem.ingredients.includes('flour') instead of menuItem.ingredients === 'flour'

The includes() method determines whether an array includes a certain value among its entries, returning true or false as appropriate.

    ],
  },
  {

searchResult = menu.some(menuItem => menuItem.ingredients.includes('flour'));
console.log(searchResult);
