Use the inbuilt function split() in JavaScript to split a string into an array of characters i.e. [ ‘c’, ‘o’, ‘d’, ‘e’, ‘d’, ‘a’, ‘m’, ‘n’,]. Use the reverse() function in JavaScript to reverse the array of characters i.e.[ ‘n’, ‘m’, ‘a’, ‘...
Decode the cookie string, to handle cookies with special characters, e.g. '$' Split document.cookie on semicolons into an array called ca (ca = decodedCookie.split(';')). Loop through the ca array (i = 0; i < ca.length; i++), and read out each value c = ca[i]). ...
