In this example, we will learn how the prototype works in JavaScript. It is rare if a JavaScript developer doesn’t use the objects while developing the functions, and the objects can make a lot of work easy for developers.The prototype is also the advanced concept associated with the objects in JavaScript. Many of you have heard about the prototypes for the first time but don’t worry. We will cover all things about the prototypes in this tutorial.What does the prototype do?The prototype is the object created for every function class when the program starts execution. However, it depends on the ... Read More
In this article, we will learn how to print Unicode characters in the console using JavaScript. No matter the platform, the software, or the language, Unicode assigns a unique number to each character.Most writing systems' characters are defined by the universal character set known as Unicode, which also assigns each character a unique number (code point). A unit of data called an abstract character (or character) is used to organize, manage, or represent textual data.Most of the modern languages' letters, punctuation marks, diacritical markings, mathematical symbols, technical symbols, arrows, emoji, and other symbols are all included in Unicode.These are different ...

In this tutorial, we will learn to display the image in the alert or confirm box in JavaScript. The alert() is the JavaScript method that displays the alert or confirms box on the top center of the screen when you invoke it.As a programmer and user, you have seen on many websites that they ask you for confirmation in the dialog box before you delete any precious thing in your user's account. Also, the alert box can be helpful to show some information when a user comes into the web page or a message.So, the default alert box can have only ... Read More
A namespace is a programming concept that gives identifiers (names of types, functions, variables, etc.) scope to avoid name conflicts. For instance, a program may need to use the same variable name in many contexts. In such a case, namespaces will separate these contexts so that the same identifier may be utilized in many namespaces.The initialization and application of namespaces in JavaScript will be covered in this tutorial. A namespace is not by default available in JavaScript. Constructing a global object that contains all functions and variables, the JavaScript Namespace feature may be repeated. Because numerous libraries and components are ... Read More
In this article, we will learn how to check the null values in JavaScript. The null value indicates the intentional absence of any object value. It is a JavaScript primitive value that is false when used in Boolean operations. This distinguishes null from the related primitive value undefined, which is an unintended absence of any object value. This is because a variable that has been declared but not given a value is undefined rather than null.You may visualize a variable as a box by using a real-world analogy. The box can hold things like a teapot, just like a variable ... Read More
In this tutorial, we will explore some of the most commonly used and famous HTTP clients that are present in Linux. A HTTP Client is a software that is mainly used to allow us to download files from the Internet. The primary reason for using HTTP clients is generally to download files, but these can also be used in case we want to debug or interact with a web server or multiple web servers.Now, let's consider the most famous HTTP Clients that are used.HTTPieWith the name that almost resembles of the famous web protocol (i.e., HTTP), HTTPie, is command line ...

Most SQL databases are relational. Relational Databases are tabular and have a pre-determined schema that organizes the data logically. Database management solutions have evolved from the classic relational paradigm to the more flexible and scalable NoSQL approach.Some say NoSQL stands for "non-SQL, " but many refer to it as SQL. NoSQL is a non-relational database management system for certain data models. These data models don't need a schema and are scalable. It offers a system-supported alternative to relational databases' tabular format for storing and retrieving data. NoSQL databases don't require a certain schema. You can store data without worrying about ... Read More
Wireless technology has completely altered the ways in which we communicate with one another and share information. Mobile radio is put into use for a wide variety of purposes, including navigation, broadcasting, transportation, space exploration, military applications, and a whole lot more. Each mobile radio application is designed to fulfil a unique set of requirements.The fundamental ideas behind mobile communications continue to be applicable across a wide variety of contexts. The Global System for Mobile Communications, or GSM for short, is the cellular technology that was widely used across the globe until it was replaced by the more efficient LTE.Towards ... Read More
Kanban and Scrum are both process tools used in Agile software development. The primary goal of the two is to increase efficiency in software development processes.Kanban is an approach that involves breaking down work into small deliverables and assigning specific tasks to team members. The Kanban method aids in the perception of software development as a whole system. Its primary goal is to gradually improve the entire development system.Read through this article to find out more about Kanban and Scrum and how they are different from each other.What is Kanban?Kanban is a visual management approach used for the workplace. It ... Read More
Because of its rising economic importance and the ever-increasing number of users, capacity in cellular systems has emerged as a primary concern for the people who design these systems. There is a maximum number of users that may be accommodated by any given cellular system before either the quality or performance of that particular cellular system is negatively impacted.As the number of users increases, so does the amount of traffic that occurs in a given period of time. As a consequence, the system progressively becomes more and more congested. As a result, the channel's capacity will continue to diminish, and ... Read More
