A variable is considered a container that can contain values of different types, these values can be numbers, characters, boolean, strings, etc. The value a container contains can access by its name and hence naming a variable is also an important aspect of JavaScript programming. This tutorial will teach you everything including the process of […]

In programming, there is often a case where we want to print out a complete sentence but there are some values of some variables that are unknown to us, or that might frequently change since they are variables. Then we can use the string interpolation method to get the desired output. By string interpolation, we

Object Oriented Programming is a programming paradigm that is centered around objects rather than functions. Before OOP we had procedural programming where the program is divided into several functions. We had data stored in different variables and functions and worked on those data to produce results. There was too much interdependence in this system. As

D3.js is a JavaScript Library that stands for Data-Driven-Documents famous for creating interactive data visualizations, especially in SVG format. It was created in 2011 with the goal of creating SVG graphics from data. D3 helps you bring data to life with the help of technologies you already know, like HTML, CSS and SVG. In this

The scope is the most fundamental concept in programming, it defines the current context of a program, i.e., where the variables can be accessed. For Example, a variable defined inside a function can’t access outside it. So its scope is Function scope as it can only be accessed inside the function.  Also Read: JavaScript Strict

JavaScript has a Date object that provides information regarding the date and time. This information can be used for different purposes such as getting the current time, comparing dates, formatting dates, reminders, etc. JavaScript Date objects represent a specific point in time and do not depend on the platform they are being used on. The

JavaScript is different from other programming languages in terms of data types, it is dynamically typed, allows changing the data type of a variable during runtime, it uses the concept of loose equality, i.e, it compares value regardless of what data type is, even it allows to declare a variable without any keyword like var,

JavaScript uses objects everywhere, it is a fundamental part of writing modern JavaScript code. JavaScript only has a few primitive data types(i.e. string, boolean, null and undefined, etc), and all the remaining data types are considered objects. Objects are non-primitive data types and can be of multiple types such as Boolean, Number, String, Array, Data,
