- Using comments within the code itself, can you provide an line by line explanation of the below JavaScript file? The file itself deals with WebGl and if that helps you. Please and thank you JavaScript file: function mat2() { var out = new Array(2); out[0] = new Array(2); out[1] = new Array(2); switch ( arguments.length ) { case 0: out[0][0]=out[3]=1.0; out[1]=out[2]=0.0; break; case 1: if(arguments[0].type == 'mat2') { out[0][0] = arguments[0][0][0]; out[0][1] = arguments[0][0][1]; out[1][0] = arguments[0][1][0]; out[1][1] = arguments[0][1][1]; break; } case 4: out[0][0] = arguments[0]; out[0][1] = arguments[1]; out[1][0] = arguments[2]; out[1][1] = arguments[3]; break; default: throw "mat2: wrong arguments"; } out.type = 'mat2'; return out; } //---------------------------------------------------------------------------- function mat3() { // v = _argumentsToArray( arguments ); var out = new Array(3); out[0] = new Array(3); out[1] = new Array(3); out[2] = new Array(3);…In this lab, you will use a timer to animate the movement of a heart image to the location where the mouse clicks, as shown below. In jacascript, please! The given web page shows a heart image. When the user clicks anywhere in the page, the startAnimation() function is called. startAnimation() determines where the user clicked and calls moveImage() with the clicked (x, y) coordinate. moveImage() moves the heart 1 pixel in the direction of the given (x, y) coordinates. Make the following JavaScript modifications using clearInterval() and setInterval() where appropriate: In startAnimation(), add an if statement that stops the timer with the ID timerId if timerId is not null. In startAnimation(), start a timer that calls moveImage(clickX, clickY) every 10 milliseconds. Save the timer ID in the timerId variable. Add an if statement in moveImage() that stops the timer with the ID timerId if (imgX, imgY) is equal to (centerX, centerY). Also set timerId to null. After the…For this task, you need to develop a JavaFX application in NetBeans that implements a LinkedHashMap class. The Java application should consist of a graphical user interface that can be used to add elements to the LinkedHashMap. There should be two TextFields to take in the element name and number. Then there should be four buttons to do four tasks, namely: add, change, remove and show all elements in the LinkedHashMap. Your buttons should have Action methods and should make use of methods in the LinkedHashMap class.When the Add button is clicked, the element name and value should be added to the LinkedHashMap. Make use of the LinkedHashMap methods to add the elements. When the user fills in the element name and number and the Add button is clicked, a message should be displayed in an alert dialog box to the user to inform them of this If no element is specified at the time the Add button is clicked, an error message should be displayed to inform the user to enter the element

Include a menu named Borders that offers three options—beveled border, etched border, and line border—as submenus with the following options: • Beveled-border submenu options: raised or lowered. • Etched-border submenu options: raised or lowered. • Line-border submenu options: small, medium, or large. Each of these options should be a submenu with three color options: black, red, and blue. Put the borders around a label containing text that describes the border, such as Raised Border, Lowered Etched Border, and so forth. Fix the highlight and shadow colors for the etched-border options to whatever colors you like, and make the small line border 5 pixels wide, the medium one 10 pixels wide, and the large one 20 pixels wide
- Add a JTextField and a JTextArea to the frame. Initialize the field to an empty string and the text area to “||”. Modify the program so that the contents of the field are appended to the area each time the user clicks the button. For example, if the user enters “xxx” in the field and clicks the button three times, the area contains “||xxx||xxx||xxx||”. Go off this code: import javax.swing.*;import java.awt.Color;import java.awt.event.*; public class MyCustomFrame extends JFrame{ // instance variables - replace the example below with your own private JButton button; private JLabel label; // add two more instance variables for JTextField and a JTextArea t // ... private static final int FRAME_WIDTH = 800; private static final int FRAME_HEIGHT = 800; public MyCustomFrame() { JPanel panel = new JPanel(); panel.setBackground(Color.RED); button = new JButton("Push Me"); // create a listener object and add it to the button //...…Write a JFrame that uses two text boxes to accept two integer numbers. When the user clicks the button "Calculate", arithmetic operations can be performed and the results of the operations can be output. the results of the operations are placed in the multi-line text area JTtextArea component. The GUI interface reference is as follows. When doing division, if the remainder is 0, the integer quotient will be displayed, otherwise, a floating point number with two decimal places will be displayed.
