   • Different Types of DOM Available to Access and Modify Content in JavaScript

     The Document Object Model (DOM) enables developers to access and control web page elements using scripting languages like JavaScript, it is a crucial part of web development. There are various DOM types that can be accessed and modified with JavaScript. The various DOM types offered by JavaScript, their capabilities, and their applications in web development will all be covered in this article. The DOM displays an HTML or XML document as a tree structure, with each node denoting a document’s element, attribute, or textual content. The document node is at the root of the nodes’ hierarchical organization, with the other nodes serving as its offspring. In addition, the DOM offers an application programming interface (API) for getting at and changing the nodes’ attributes and content.

     To access and modify the content of a web page using the DOM, you can use one or more of the following approaches:

     • getElementById: This method is used to access an element in the document by its unique ID attribute.

   • Types of Arrays in JavaScript

     A JavaScript array is a collection of multiple values at different memory blocks but with the same name. The values stored in an array can be accessed by specifying the indexes inside the square brackets starting from 0 and going to the array length – 1([0]…[n-1]).

     A JavaScript array can be classified into multiple types:

     Table of Content

     • Numeric Array
     • String Array
     • Array of Arrays (2D Arrays)
     • Array of Objects
     • Mixed Arrays
     • Array with empty values

     Numeric Array

     A numeric array is an array that contains only the numeric values as elements that are stored at different memory locations but in a consecutive manner.

     Example: The below code example is an implementation of defining and using a numeric array.

     Javascript

     const numArr = [1, 2, 3, 4, 5];console.log("Numeric Array: ", numArr);console.log("First element: ", numArr[0]);-

     Output

     Numeric Array: [ 1, 2, 3, 4, 5 ]First element: 1-

   • Events of an image in HTML and JavaScript

     You can try jquery hover to keep the current actions.

     fiddle example:

     <img src="image_1.png" />-<script>$('img').hover( function(){ $(this).attr('src','image_2.png'); }, function(){ $(this).attr('src','image_1.png'); },);</script>

     Maybe, other option could be a css :hover and :active filters, using background propertie. See this css example

     .Myimg{ display:block; width: 100px; height:100px; background-image:url('img1.jpg');}.Myimg:hover{ background-image:url('img2.jpg');}

   • How to call different types of functions in Javascript

     Top Answer

     Answered Jan 16, 2014 · 2 votes

     There are no different formats of functions. All of them are defined with function keyword followed by arguments and body. If you have a function foo then you call it via foo(); (you can pass arguments as well, foo(1,2,3);). There are more complex ways of calling functions, for example via foo.call or foo.apply but I don't think it is necessary to talk about that here.

     Note that functions in JavaScript are first class citizens. That means that they can be treated as objects. In particual you can pass them to another function. Have a look at this example:

     var foo = function(fn) { return fn()+1;};

     What happens here? foo takes a function as an argument (we know that because fn() is called in body), calls it and adds 1 to result. So if I call foo like this:

     foo(function() { return 1;});

     what would the result be? That's a simple example. Consider something more complex:

     var foo = function(list, fn) { var res = []; for (var i = 0; i < list.length; i++) { var mapped = fn(list[i]); res.push(mapped); } return res;};

     This is a simple version of the .map method on lists. So it takes a list and a function as arguments, then applies the function to each element of the list and returns a new list:

     > foo([1, 2, 3], function(el) { return -el; });[-1, -2, -3]

     It is the same as calling

     > [1, 2, 3].map(function(el) { return -el; });[-1, -2, -3]

   • Different ways of writing functions in JavaScript

     JavaScript Function is a block of code that is designed to perform a task and executed when it is been called or invoked.

     Below are the ways of writing functions in JavaScript:

     Table of Content

     • Function Declaration
     • Function Expression
     • Arrow Functions

     Function DeclarationFunction Declaration is the traditional way to define a function. It is somehow similar to the way we define a function in other programming languages. We start declaring using the keyword “function”. Then we write the function name and the parameters.

     Example: Below is an example that illustrates the use of Function Declaration.

     Javascript

     // Function declaration function add(a, b) {             console.log(a + b);} // Calling a functionadd(2, 3);

     After defining a function, we call it whenever the function is required.

     Function ExpressionFunction Expression is another way to define a function in JavaScript. Here we define a function using a variable and store the returned value in that variable.

     Example: Below is an example that illustrates the use of Function Expression.

     Javascript

     // Function Expressionconst add = function (a, b) {    console.log(a + b);} // Calling functionadd(2, 3);

     Here, the whole function is an expression and the returned value is stored in...
