Async/Await in JavaScript

Async/Await in JavaScript

Introduction: The world of asynchronous programming in JavaScript, with a focus on the powerful async/await syntax. Before we dive into the specifics of async/await, let’s take a moment to understand the challenges posed by synchronous code execution in JavaScript. Section 1: Synchronous Code and Its Limitations: JavaScript traditionally executes code synchronously, meaning it processes one Continue Reading »

Gradle vs. Maven: Which Build Tool to Choose?

Gradle vs. Maven: Which Build Tool to Choose?

Gradle and Maven are both popular build tools used in the software development process, particularly in Java projects. They serve the purpose of automating the process of building, testing, packaging, and managing dependencies for a software project. While they share common goals, they have distinct characteristics and approaches.  Gradle:  Build Script Language:  Language: Gradle build Continue Reading »


Event Loop in Javascript

Introduction The event loop is a mechanism that is an integral part of the browser environment and runs continuously, whether the code is synchronous or asynchronous. The primary function of the event loop is to manage the execution of JavaScript code, placing callbacks in a queue and pushing them onto the call stack when they Continue Reading »

Understanding Tree Shaking in JavaScript: Trimming the Fat from Your Code

If you’ve ever wondered why your JavaScript files are bigger than they need to be, you might be interested in a neat optimization technique called “tree shaking.” No, it doesn’t involve vigorously shaking your computer – it’s a process that helps you get rid of unnecessary code and make your applications faster and more efficient. Continue Reading »

Memoization in Javascript

Memoization is a powerful technique used in computer science to optimize the performance of functions that are called repeatedly with the same arguments. In JavaScript, memoization is particularly useful for expensive computations that involve complex algorithms or data structures. At its core, memoization involves caching the result of a function based on its input arguments. Continue Reading »

Role of equal() and hashCode Methods()

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 »

We can generate request models, response models, and controllers of API. 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 »

Closure in Javascript

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 »

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 »

JavaScript Arrays

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 »

HOISTING IN JAVASCRIPT (Variables & Function)

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 »

Access Modifiers in Java

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 »

Recursion vs Dynamic Programming — Fibonacci

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 in Java

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 »

Debouncing in JavaScript

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 »

Currying in JavaScript

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 »

Currying in JavaScript

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 in javaScript

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 »

Destructuring in JavaScript

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 »

 JavaScript Closures

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 »
