Both Firewall and Antivirus are security tools that protect the computer systems as well as the network infrastructure from virus, worms, Trojans, and other such cyber-threats. Firewalls scan and evaluate the data packets before they enter into a network, and then they either allow or deny the data packets based on certain predefined rules setup by the network protocols. Firewalls can be implemented both at the software and hardware levels, while an antivirus program can be implemented only at the software level. Read through this article to know more about Firewall and Antivirus and how they are different from each ... Read More
Let’s start our article with an explanation of how to find the sum of even factors of a number but what are factors? Factors are the numbers which completely divide the given number leaving zero as remainder or we can say factors are the multiples of the number. Example 1 − If we are given a number 60 Factors of 60 (6*10=2*3*2*5) are 2, 5 and 3 But according to the question, we must find out the sum of even factors so, in the above given example, the even factor will be only 2. Also, if the given number is an ... Read More
The terms "parameters" and "arguments of a function" are frequently used synonymously in JavaScript, despite the fact that there is a substantial distinction between the two. The function parameters are included when we define a function. While defining a function, you may also specify a list of variables; these variables are referred to as function parameters. On the other hand, "function parameters" are the values we pass when we call or execute the newly created function. In JavaScript, the variables listed in the function declaration serve as the argument values. The arguments that are part of the function definition are ... Read More
A string representation of the given node's name is returned by the nodeName property. When a node has attributes, it produces a string with the name of the corresponding attribute. When a node is an element, it returns a string with the name of the tag. This property can only be read. Each element on a webpage can be accessed through a node, which is a component of the DOM tree. Every node is an object with a number of methods and properties; this is why nodes are sometimes known to as node objects. The browser builds a tree ... Read More
The user's current location can be found using the getCurrentPosition() method. The Geolocation API that HTML5 offers us allows us to know the user's geographic location. The Geolocation API provides the latitude and longitude of the user's current location, that are thereafter delivered to the backend via JavaScript and displayed on the website. The read-only longitude property of the GeolocationCoordinates interface is a double-precision floating point value that indicates a location's longitude, expressed in decimal degrees. The GeolocationCoordinates object is a component of the GeolocationPosition interface, since it is the object type delivered by Geolocation API calls which collect and ... Read More
In JavaScript, you may extend both classes and objects with the extends keyword. It is frequently used to build classes that are children of other classes. In addition to built-in objects, customized classes can also be subclass using the extends keyword. The classes serve as the blueprint for a real-world item so that we may easily change, access, and utilise them in programming. It is specified to establish an abstract data type to hold a specific sort of information together with the methods for manipulating that information. You use the extends keyword to use class inheritance. Any constructor with the ... Read More
The document's current title can be obtained or changed using the document.title attribute. When present, the value of the is used by default. You can change or get the current title of the document using the document.title attribute. By providing a new title as a string to this attribute, the page's title can be changed. The chosen title will immediately be reflected in the website's title. In this article you will see two types of methods used to change or use Document.title() use in JavaScript Using the document.title property − You may set or get the current title ... Read More
JavaScript is a lenient object-oriented language. We'll look at various JavaScript object creation methods in this article. It is crucial to know that JavaScript is an object-oriented language based on prototypes instead of classes before moving on. It can be more difficult to understand how JavaScript enables you to build hierarchies of objects and to get an inheritance of properties and their values because of this different foundation. Programming objects can combine variables, functions, and data structures. In other words, objects can hold values, you can use objects to manipulate values, and you can combine values into more complicated objects, ... Read More
Property accessors offer dot notation or bracket notation-based access to an object's properties. Associative arrays are a good way to understand objects (a.k.a. map, dictionary, hash, lookup table). The names of the property names are the keys inside this array. A difference between properties and methods is frequently made when discussing an object's properties. But the distinction between a property and a technique is simply an established practice. When a property's value is a reference to an example of a Function, for example, that property can be invoked to perform a function. Syntax ObjectName[propertyName] You will study JavaScript getter ... Read More
To remove an element from an array with JavaScript, use the shift() and pop() functions. However, there is a slight distinction among them. While pop() removes the last element from an array, shift() removes the first element from an array. When using the shift() method, the value that was deleted is returned after the element at the zeroth position is removed and values at subsequent indexes are shifted downward. The return value is undefined if the length property is 0. A function that modifies data is shift(). Both the substance and the length of this are altered. Use arr.slice(1) instead ... Read More
