Objective:To add scripting to the existing web page and work with JavaScript Es-6 features like class, object , getter methods and collection. Problem Description:As part of a simple billing application, you are provided with an html page to obtain inputs for item number, item name, price & quantity. Using the ES-6 collections, add every item object into a Set and iterate through it to find the total cost to be paid. On adding each item object into Set, it must also get added to the table as a new record. Refer to the screenshot. Following are the files that contain code snippets index.html HTML for webpage (complete implementation is given for you). You only have to run this. No change needs to be done in this file. script.js Add your code to this file for the functions given. Procedure to complete the exercise Class Properties Methods Item itemNumberitemNamepricequantity Include constructor with properties and getter methods for Item properties…
In this task we want you to help fill in the links on our Whales information page: The first link should be linked to a page called whales.html, which is in the same directory as the current page. We'd also like you to give it a tooltip when moused over that tells the user that the page includes information on Blue Whales and Sperm Whales. The second link should be turned into a link you can click to open up an email in the user's default mail application, with the recipient set as "whales@example.com". You'll get a bonus point if you also set it so that the subject line of the email is automatically filled in as "Question about Whales".

You are expected to complete the skeleton code for a web server by providing the missing code in the sections marked with comments #Fill in start and #Fill in end. Each section may require one or more lines of code.It is not recommended to deviate or remove any skeleton.However, do not you skeleto code,You never need to modify code outside the start and end fill areas, do so at your own peril. Using the skeleton code provided, you will develop a web server that handles one HTTP request at a time. Your web server should: Accept and parse the HTTP request Get the requested file from the server’s file system Create an HTTP response message consisting of the requested file preceded by header lines Send the response directly to the client. For the header ‘Server’ feel free to use one of your own choice/making. Ensure you include all relevant header lines. If you forget any required headers, GradeScope will tell you. If the requested file is not present on the server, the server…
Setup Branch name assignment1 Directory assignment1 Package name assignment1 Instructions Create a node server with the following requirements: Use the dotenv package to manage your development environment variables. PORT should be 3000 HOST should be localhost Endpoints /dotted Only GET requests are allowed. This endpoint will respond with the HTML content type. This endpoint will take two required query parameters: word1 and word2. The endpoint will take the two words and create a string that is the two words separated by enough “.” characters to make the length of the string 30. For example if word1 is “turtle” and word2 is “153” the output should be: turtle.....................153 The response body should be the string wrapped in a <pre> tag. /fizzBuzz Only GET requests are allowed. This endpoint will respond with the HTML content type. This endpoint will take two required query parameters: start and end. The endpoint will iterate from start to end and for each…

Suppose there is a MySQL database named MyDatabase, the name of database server is DatabaseServer, User Name for the database server Abdullah and Password is “Farooqxy%”. There is one table named tbl_Projects (ProjectSID, ProjectTitle, ProjectSupervisor,CellNo,Email). You are required to design a HTML page to get the value for each of these attributes.
