A unary function is a mathematical function that takes only one argument or input. It is a function of a single variable, which means that it operates on a single operand. The term “unary” comes from the Latin word “unarius” meaning “consisting of one.” For example, the function f(x) = x^2 is a unary function Continue Reading »
In Java, HashMap is a widely used data structure that stores elements in key-value pairs. It provides constant-time performance for basic operations like adding, removing, and accessing elements. The implementation of HashMap relies heavily on the equals and hashCode methods, which are used to ensure the uniqueness of keys and the efficiency of lookup operations. Continue Reading »
Introduction:- Open API (open application programming interface) Open API Generator can generate code based on an Open API yaml specification.

Following are the steps to create java code from Open API:- Step 1:-Create a yaml file for your API By using this Swagger.io, below Continue Reading »
As per the definition of Javascript Developer, Closure is defined as the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). But what is meant by the terms “enclosed”, “surrounding state“, and lexical environment? No need to worry, we’ll discuss their terms and closure in this article with Continue Reading »
Figure 1:Features of Java 8 JAVA 8 is one of the major feature releases of “JAVA programming language” development. It is one of the revolutionary releases of the development of software platforms. The initial version of Java 8 was released on 18 March 2014. It is responsible for upgrading Java programming, tools, JVM, and libraries. Continue Reading »
HTML forms allow users to enter data into input fields that accept text, passwords, emails, numbers, colors, phone numbers, dates, and more. Once all inputs have been collected, the form can be submitted for further processing using the submit button. React Form HTML form elements maintain their own state. Updating this state property is only Continue Reading »
As you already know everything in JavaScript is an object. One of the objects is so weird in JavaScript called Date(). Today, even experienced devs get nervous with Date() and reach for libraries like ‘date-fns’ and ‘moment’. Yes, you read it at the right moment. which is the most popular library while struggling with date Continue Reading »
An array is a linear data structure and collection of items stored at a contiguous memory location. Pairs of square brackets [ ] represent an array and all elements are comma (,) separated. An Array can hold multiple values(elements) of any type i.e (String, Number, Boolean, objects, and even other Arrays ) under a single Continue Reading »
The map method holds key and value pair, the key can be any datatype. The map method is the function for every array element and returns the new part. The map method does not change the original array. We can create a map method passing an Array to a new Map(). We can set the Continue Reading »
A Person with another programming background is definitely confused with hoisting in Javascript. So let’s deep dive into the hoisting in javascript The Javascript engine creates the global execution context when we execute a piece of Javascript code. Global Execution Context has two phases : (i) Creation Phase (ii) Execution Phase Definition: During the creation Continue Reading »
Introduction: In Java, we have to deal with classes, methods, variables, etc. Let’s suppose we have a class and we need to use variables or methods in different classes/packages. OR we want to specify that a variable or method will be accessed within a defined area. To manage the accessibility of any variables, methods, or Continue Reading »
Introduction of Recursion and Dynamic Programming: Recursion is the process in which a function calls itself until the base cases are reached. And during the process, complex situations will be traced recursively and become simpler and simpler. The whole structure of the process is tree-like. Recursion does not store any value until reaching the final Continue Reading »
Annotations are used to provide metadata about class or method in java and can be used while compiling the program. Annotations were introduced in Java 1.5 version. Before that, we had an XML file for configuration. We write annotations with the ‘@’ sign, for example, @Override annotation. Here ‘@’ sign tells the compiler about the Continue Reading »
Core Java Concepts: Serialization Serialization is defined as the process of converting an object into a sequence of bytes that can persist in a database or can be sent through streams. Serialization saves the state of objects for recreation without having to reprocess them on different platforms. Serialization is useful for storing, Transmitting the state Continue Reading »
Debouncing in JavaScript Debouncing is a technique, use of Denouncing we can write better performance code that gets executed repeatedly within a period of time Debouncing ensures that time is taken to task, debouncing prevent unnecessary event on the web Debouncing code ignores unnecessary calls until the call has stopped for a particular time period. Continue Reading »
What is currying? Currying is a technique of evaluating a function with multiple arguments, into a sequence of functions with a single argument. OR In other words, while a function, rather than taking all arguments at one time, takes the primary one and goes back to a new function that takes the second and returns Continue Reading »
The process of placing a list of items in a specified manner is known as Sorting. Some common criteria for sorting are alphabetical and numerical. It can be done in an ascending manner or in descending order. We all know that Collections.sort has the ability in sorting an arrayList for example, alphabetically if they are Continue Reading »
Currying is a task that takes one argument at a time and brings back a new task awaiting the next argument. It is a modification of functions that translate function from callable as f (a, b, c) to f (a)(b)(c). In this article, we will look at what currying is in Javascript, why you should Continue Reading »
Hoisting is a phenomenon in javaScript by which you can access variables and functions even before you have initialized them or you have put some value on them. you can access it without any error. Hoisting allows functions to be safely used in code before they are declared. for Example: var x=7; function getName(){ console.log(“hoisting Continue Reading »
The Destructuring introduced new features of ES6.JavaScript provides a mechanism to handle the array and properties of objects in a much more innovative way. this mechanism is called destructuring. destructuring means implies a complex structure into the simpler parts. Destructuring allows us to extract multiple properties from an object or an Array. It is a Continue Reading »
A closure is a combination of a function bundled together (enclosed) with references to its surrounding state (the lexical scope). Lexical scoping The stance of a variable asserted in the source code denotes its scope in syntactic figuring. For example: let name = ‘John’; function greeting() { let message = ‘Hi’; console.log(message + Continue Reading »
Closures:- One of the greatest features in javascript is closures and it’s widely used but a little bit confusing term of javascript. So let’s understand what is closures. In simple words closures function are gives you access to an outer function from the inner function. We will start the fundamental term lexical scope known as Continue Reading »
Event Bubbling: In the event bubbling, an event starts at the most specific element and then flows upward toward the least specific element. For better understanding let’s take an example:-Suppose we have created a div inside the body tag and then we create a button inside that div. Let’s add the “Click” function on the Continue Reading »

By default, every function has a property called prototype this property by default is empty and you can add properties and methods to it and when you create an object from this function. The object inherits its properties and methods. It has been often confusing to the beginners “How Prototype Works in Javascript” and with this, you will also get the Continue Reading »
