1. Open the project named BooksDonation. 2. Inside the project you will find a folder called data that contains catalog.books.json 3. Create a class named BooksRepo and write the following methods shown in the table below using async-await 4. Create a test file called BooksRepo.spec.js that tests all the methods inside the BooksRepo.js. Make sure that you write all the tests using Mocha and Chai. 5. Finally create an app.js file to test BooksRepo class (no need to use mocha here) getBook(bookName) Returns the book object if it exists, otherwise null getBooksWithPageCount More ThanX(pageCount) Returns all the books that have a pageCount more than the given pageCount. Eg. If the user calls the function with pageCount-1000. It should return all the books that have pagecount >1000 Returns all the books authored by that specific author Note: some books have more than one author. You should consider those too and return them as well getAuthorBooks(author) getAuthorsBookCount() Returns a map that contains author name anda count of books their authored Eg Author Name James Ali Book Count 4 getBooksbyCatagory(category) Returns all the books of that category E.g. category Java should return all the books that are related to java You should use async/await(or promises), and other JavaScript features such as arrow functions, array functions (.map, .reduce, filter, .splice,.sort..), spread operator, object literals, and classes wherever required 1.
