Functions and Function Expressions

1. Create a module for working with DOM. The module should have the following functionality

   • Add DOM element to parent element given by selector
   • Remove element from the DOM by given selector
   • Attach event to given selector by given event type and event hander
   • Add elements to buffer, which appends them to the DOM when their count for some selector becomes 100
   • The buffer contains elements for each selector it gets
   • Get elements by CSS selector
   • The module should reveal only the methods

       var domModule = …
       var div = document.createElement("div");
   
       //appends div to #wrapper
       domModule.appendChild(div,"#wrapper"); 
   
       //removes li:first-child from ul
       domModule.removeChild("ul","li:first-child"); 
   
       //add handler to each a element with class button
       domModule.addHandler("a.button", 'click', function(){alert("Clicked")});
       domModule.appendToBuffer("container", div.cloneNode(true));
       domModule.appendToBuffer("#main-nav ul", navItem);

• Create a module that works with moving div nodes. Implement functionality for:

  • Add new moving div element to the DOM
    • The module should generate random background, font and border colors for the div element
    • All the div elements are with the same width and height
  • The movements of the div nodes can be either circular or rectangular
  • The elements should be moving all the time

      var movingShapes = …
  
      //add element with rectangular movement
      movingShapes.add("rect"); 
  
      //add element with ellipse movement
      movingShapes.add("ellipse");

• Create a module to work with the console object. Implement functionality for:

  • Writing a line to the console
  • Writing a line to the console using a format
  • Writing to the console should call toString() to each element
  • Writing errors and warnings to the console with and without format

      var specialConsole = …
      specialConsole.writeLine("Message: hello");
      specialConsole.writeLine("Message: {0}", "hello");
      specialConsole.writeError("Error: {0}", "Something happened");
      specialConsole.writeWarning("Warning: {0}", "A warning");
