Are you struggling with JavaScript assignments? Are those complex codes causing you sleepless nights? or If you are thinking, 'Who can write my javascript assignment', Fret not! Welcome to programminghomeworkhelp.com, your ultimate destination for mastering JavaScript. In this post, we delve into advanced JavaScript concepts, unraveling intricate problems, and providing expert solutions. So, if you're looking for assistance with your JavaScript assignments, you're in the right place. Let's dive in!
Question 1:
Challenge:
You are given an array of objects representing different books in a library. Each object contains information about the book, including its title, author, and the number of pages. Write a JavaScript function that takes this array as input and returns the average number of pages across all books.
Solution:
```javascript
function calculateAveragePages(books) {
let totalPages = 0;
books.forEach(book => {
totalPages += book.pages;
});
return totalPages / books.length;
}
// Example usage:
const library = [
{ title: 'The Great Gatsby', author: 'F. Scott Fitzgerald', pages: 218 },
{ title: 'To Kill a Mockingbird', author: 'Harper Lee', pages: 281 },
{ title: '1984', author: 'George Orwell', pages: 328 }
];
const averagePages = calculateAveragePages(library);
console.log("Average number of pages:", averagePages);
```
Explanation:
This solution employs a forEach loop to iterate over each book in the library array, accumulating the total number of pages. Finally, it calculates the average by dividing the total pages by the number of books in the library.
Question 2:
Challenge:
You are given a string containing a series of words separated by spaces. Write a JavaScript function that reverses the order of words in the string.
Solution:
```javascript
function reverseWords(str) {
// Split the string into an array of words
const words = str.split(" ");
// Reverse the array
const reversedWords = words.reverse();
// Join the words back into a string
return reversedWords.join(" ");
}
// Example usage:
const sentence = "JavaScript is awesome";
const reversedSentence = reverseWords(sentence);
console.log("Reversed sentence:", reversedSentence);
```
Explanation:
This solution first splits the input string into an array of words using the split method. Then, it reverses the array using the reverse method. Finally, it joins the reversed array back into a string using the join method.
