In today’s fast-paced web development world, creating smooth and responsive user experiences is key. One way to achieve this is through AJAX (Asynchronous JavaScript and XML), a powerful technique that allows web pages to communicate with servers and...
TOPICS Callbacks Promises Async/Await .then/.catch finally Why do we need promises in Javascript : let's understand this first by some basic topics Callbacks: to understand promises we first need to understand callbacks. callbacks are function...
Closures !? Closures are blocks of code you can pass around in Swift. They're like functions but lighter and more flexible. Closures let you run code on demand, pass it as a variable, or use it for callbacks. UsesClosures make code compact and powerf...
What is Asynchronous Programming? Asynchronous programming is a programming technique that allows tasks to run concurrently (at the same time) without blocking the execution of other tasks. What is a Future? A Future is the result of an asynchronous ...
Why Go Async? Imagine you’re racing a car, but every time your car needs a pit stop, the entire race pauses until it’s finished. This wouldn’t make sense! In a race, every car runs independently, so one car’s pit stop doesn’t stop others. Asynchronou...
Here are some examples of asynchronous programming in JavaScript using callbacks, Promises, and async/await. 1. Using Callbacks A callback is a function passed as an argument to another function, which is then executed after some operation completes....
Welcome to Day 11! Today, we’re diving into a fundamental concept in JavaScript’s approach to handling asynchronous operations: Promises. If you’ve ever been stumped by complex asynchronous code, understanding promises will be your gateway to more re...
JavaScript, by design, is a single-threaded language 🧵. This means it can only execute one task at a time. However, many modern applications require operations like network requests 🌐, file handling 📁, or database queries 🗄️, which can take time ...
JavaScript is often described as a single-threaded language, but it manages to handle tasks like fetching data from servers, updating the UI, and responding to user events seamlessly without blocking or freezing. This is made possible by a magical co...
Introduction: JavaScript is asynchronous, which means certain actions (like fetching data) don’t block the rest of your code. Promises and async/await help manage these non-blocking actions. Working with Promises: A promise is an object that represen...
