Using private methods has a simple underlying concept. In this situation, you can declare private methods or private properties, which are used to hide a class's internal functionality from those other classes, whenever you wish to keep something private, whether it be a method or a property. You can include private fields, static methods, instance methods, and getters and setters that are only accessible to you. Truly private fields and methods are delivered through private class features, with the language maintaining that privacy rather than a custom. Benefits include preventing naming conflicts between class features and the other of the ... Read More
A property of an element called "children" delivers all child elements of the element as objects. We will learn how to use Javascript to obtain the child element of the parent in this tutorial. The challenge is to use JavaScript to choose a certain element in an HTML document and retrieve all of the parent element's children. There are 2 methods for doing this to obtain the child element − making use of the children property making use of the querySelector Method Through the use of examples, we will discuss both strategies and understand how they are applied. ...

JavaScript provides us with functions, that are a collection of pre-defined instructions or statements that are only carried out when we call the function that contains this code. The function accepts one or more arguments as input and output. You can pass values or references for the input arguments. All function parameters are always given by value in JavaScript. It indicates that JavaScript inserts copies of variable values into function parameters. The passing variables outside of the function are not affected by any modifications you make to the function's internal arguments. Or, to put it another way, changes made to ... Read More
Clone often refers to copying a value from one place to another. We duplicate one value to another using JavaScript, which is known as cloning. In JavaScript, there are actually two different sorts of copying. The ability to distinguish between deep and shallow clones is something that every programmer, regardless of experience level, should understand. Since this essay is about deep clones, we shall investigate deep clones in detail. Any data type, including composite data types like arrays and JavaScript, as well as primitive data types (like string and number), can experience the concept of cloning. Therefore, we must understand ... Read More
The Math object, a built-in object with attributes or methods for carrying out mathematical operations, has the native implementation of the random() method in JavaScript. As its name suggests, the random() method aids in the generation of random numbers. The return value of the Math.random() method is a floating-point, sort of semi number between 0 (inclusive) and 1. (exclusive). This is defined mathematically by the equation 0 = x 1. The Math.random() function will return a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0 but not 1) with an essentially uniform distribution throughout that ...

The key-value pairs are stored using JavaScript WeakMap Objects. A WeakMap object differs from a Map object in that such objects should be weakly referred and "object" should be stored in the WeakMap object as a key. In comparison, you can add simple values like strings, booleans, symbols, and numbers to the Map objects. WeakMap objects are stored loosely, therefore if the references to a particular key are dropped or the object is erased, the garbage collection will drop the WeakMap element after it has verified that the value is mapped to the relevant object. The JavaScript built-in function weakMap.has() ... Read More
What is Routing? The process of determining a path for traffic inside a network or across or across different networks is known as routing. Routing occurs in a wide range of networks, including circuit-switched networks like the public switched telephone network (PSTN) and computer networks like the Internet. Routing is the higher-level decision-making in packet switching networks that sends network packets from their source to their destination through intermediate network nodes using particular packet forwarding techniques. The passage of network packets from one network interface to another is known as packet forwarding. Routers, gateways, and other network hardware devices are ... Read More
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
