Interfaces in typescript is one of the most important concept that helps maintain clean, readable, and scalable code. But what exactly is an interface in typescript, why should you use it, and what happens if you don’t? Let’s dive in to understand it clearly, step by step, with practical examples. What is an Interface in […]
Understanding Why data1 === data2 Returns False in JavaScript In JavaScript, objects are one of the most commonly used data structures. However, understanding how objects are compared in JavaScript can sometimes be tricky. One of the most common questions developers face is: Why does data1 === data2 return false even though both objects have the […]
HTTP interceptors in Angular are a powerful feature in Angular that allows you to intercept and manipulate HTTP requests or responses globally. They provide a centralized place to handle common concerns like authentication, logging, error handling, or modifying request/response data before it reaches your components. By using interceptors, you can ensure that your HTTP calls […]
Breaking It Down Let’s analyze what each line does: The JavaScript Event Loop JavaScript is single-threaded, which means it can only execute one operation at a time. But it can handle asynchronous tasks like timers, network requests, and user events without blocking the execution of other code. This is achieved using something called the event […]
Understanding JavaScript’s Asynchronous Behavior: A Look at setTimeout() and the Event Loop JavaScript is known for its asynchronous nature, which allows developers to manage multiple tasks without blocking the execution of other code. To better understand how this works, let’s break down the following code snippet and see how JavaScript handles both synchronous and asynchronous […]
In JavaScript, the bind() method is one of the most powerful and useful tools for controlling the behavior of this inside functions. Understanding how and when to use bind() is essential for working with functions, especially in complex scenarios where the context of this can change unexpectedly. what is the bind() Method? The bind() method […]
In JavaScript, closures in JavaScript are one of the most powerful and essential concepts for any developer to understand. They enable functions to remember and access variables from their lexical scope, even after the outer function has finished execution. This feature allows for more modular, efficient, and reusable code. Understanding closures in JavaScript is critical […]
Constraints: I have to use core JavaScript. Frameworks are not allowed. Find the index of the array element you want to remove using indexOf, and then remove that index with splice. The second parameter of splice is the number of elements to remove. Note that splice modifies the array in place and returns a new array containing the elements that have been removed. For completeness, […]
JavaScript is a fundamental part of modern web development, driving dynamic content and interactive features. However, poorly optimized JavaScript can significantly slow down your website, leading to an inferior user experience, higher bounce rates, and poor SEO performance. JavaScript performance optimization is essential for achieving faster page load times, improving search engine rankings, and keeping […]
Today, let’s explore a code snippet to understand how the array length behaves when we manipulate the array in non-conventional ways: Code Snippet: 1. Initializing the Array: Here, we initialize an array numbers with three elements: 1, 2, and 3. In JavaScript, arrays are zero-indexed, meaning the first element is at index 0, the second […]
