The code is great. I just see some indentation improvements (like, keep all lines following the spaces conventions)

const normalizedSearch = searchString.trim().toLowerCase();

// Define the book title and convert to lowercase
const bookTitle = "The fundamentals of JavaScript".toLowerCase();

// Check if the book title contains the search string
return bookTitle.includes(normalizedSearch);
}

// Test
console.log(isBookApplicable("javascript"));
console.log(isBookApplicable("javascript "));
console.log(isBookApplicable("python"));
console.log(isBookApplicable("JavaScript"));
console.log(isBookApplicable("JAVASCRIPT"));
