const suitableRecipes = recipes.filter(recipe => {
  const hasLikedIngredient = recipe.ingredients.some(ingredient => guest.loves.includes(ingredient))
  const hasDislikedIngredient = recipe.ingredients.some(ingredient => guest.dislikes.includes(ingredient))
  return hasLikedIngredient && !hasDislikedIngredient
})

suitableRecipes.forEach(recipe => console.log(recipe.name))

Pseudocode

     • It contains at least one ingredient the guest loves (hasLikedIngredient).
     • It does not contain any ingredients the guest dislikes (!hasDislikedIngredient).

6. Print the suitable recipes:
