Tell us what’s happening:
/*
This is a general comment-The problems that I am seeing are written badly-the instructions are not clear in what they are asking, that should be solved. I have been in too many sprints/daily stand ups to see that this is a problem because the ask needs to be very clear for any programmer to solve, step by step. I am noticing lately that the problem sets are written haphazardly. Please update.*/
Your code so far
// the global variable
var bookList = ["The Hound of the Baskervilles", "On The Electrodynamics of Moving Bodies", "Philosophiæ Naturalis Principia Mathematica", "Disquisitiones Arithmeticae"];
/* This function should add a book to the list and return the list */
// New parameters should come before the bookName one
// Add your code below this line
function add (bookName) {
return bookList.push(bookName);
// Add your code above this line
}
/* This function should remove a book from the list and return the list */
// New parameters should come before the bookName one
// Add your code below this line
function remove (bookName) {
if (bookList.indexOf(bookName) >= 0) {
return bookList.splice(0, 1, bookName);
// Add your code above this line
}
}
var newBookList = add(bookList, 'A Brief History of Time');
var newerBookList = remove(bookList, 'On The Electrodynamics of Moving Bodies');
var newestBookList = remove(add(bookList, 'A Brief History of Time'), 'On The Electrodynamics of Moving Bodies');
console.log(bookList);
