Day.js is a lightweight JavaScript library used for parsing, validating, manipulating, and formatting dates. It is a popular alternative to moment.js due to its smaller size and improved performance. Day.js works seamlessly with modern browsers and has an API that is almost identical to moment.js, making it easy to switch between the two libraries. Key Features: + Immutable: Day.js objects are immutable, meaning that all operations return a new instance without modifying the original object. + Chainable API: The API allows you to chain multiple methods together for concise and readable code. + Locale Support: You can easily change the locale to format dates according to regional preferences. + Plugin System: Day.js is highly modular and supports plugins to extend its capabilities without bloating the core library. + Timezone and Duration Handling: With plugins like dayjs/plugin/timezone and dayjs/plugin/duration, you can easily manage time zones and durations. #dayjs

What is usesState ? useState is a hook in React, a JavaScript library for building user interfaces. Hooks are functions that let you use state and other React features in functional components, which are a way of writing React components using JavaScript functions instead of classes. The useState hook specifically allows functional components to have stateful logic. It returns a stateful value and a function to update that value, allowing you to declare state variables in your functional components. The state variables can hold data that may change over the lifetime of the component. When the state variable changes, React re-renders the component to reflect the updated state.

Rules of Hooks To ensure hooks work correctly, React enforces two rules: Only call hooks at the top level: Hooks should not be called inside loops, conditions, or nested functions. Only call hooks from React function components or custom hooks: You cannot call hooks from regular JavaScript functions. Custom Hooks Custom hooks allow you to extract reusable logic into separate functions that can be shared across multiple components. These functions must follow the naming convention of starting with use. Example of a custom hook: javascript function useCounter(initialValue) {  const [count, setCount] = useState(initialValue);  const increment = () => setCount(count + 1);  return { count, increment }; } Conclusion React Hooks revolutionize how developers manage state and side effects in functional components by making code more modular and easier to maintain. The most commonly used hooks are useState, useEffect, and useRef, but learning others like useMemo, useCallback, and custom hooks will help optimize performance and code reuse

Ever wondered how JavaScript handles multiple tasks simultaneously despite being single-threaded? The secret lies in the Event Loop! 🌀 What is the Event Loop? The Event Loop is JavaScript’s way of managing asynchronous operations. It ensures your code runs smoothly without getting blocked, enabling responsive web experiences. 🚀 How It Works: 1. Call Stack: Executes functions sequentially. 2. Task Queue: Holds tasks waiting to run. 3. Event Loop: Monitors the Call Stack and moves tasks from the Task Queue when the Stack is clear. This process lets JavaScript handle multiple operations, like user interactions and data fetching, without freezing up. 💡 In the example shared in Image below, Despite setTimeout being called with 0 delay, "This runs last" logs after "End" because the Event Loop processes it after the synchronous code completes. 📜 Hit 👍 Like and follow for daily bite-sized knowledge! #JavaScript #EventLoop #AsyncProgramming #WebDevelopment #frontend

🚀 Unlocking the Magic of JavaScript’s Event Loop! 🌀 JavaScript may be single-threaded 🧠, but it handles asynchronous operations like a pro! Want to know the secret sauce behind it? 🍲 It’s the Event Loop! 🎡 Let's dive in! 💻👇 🔄 Step-by-step Breakdown: 1️⃣ Call Stack: 📚 Where JavaScript keeps track of the functions to execute. It works on a LIFO (Last In, First Out) basis. Each function gets pushed here, and once done, it’s popped off. 2️⃣ Web APIs: 🌐 These are the magic workers that handle async tasks like setTimeout, fetch, or DOM events. JavaScript itself doesn’t do the waiting, it hands these tasks off to Web APIs while continuing with the rest. 3️⃣ Callback/Task Queue: 📥 Once an async task finishes (like a network request 📨), its callback function is added to this queue. The task waits here until the Call Stack is free. 4️⃣ Event Loop: 🔄 The real hero! It constantly checks the Call Stack, and when it's empty, it picks up tasks from the Callback Queue 🏃♂️ and pushes them onto the Call Stack for execution. 💡 Key Insight: The Event Loop ensures that async code (like API requests, timers) runs without blocking the execution of the main thread, keeping your app responsive! 🚀💥 By mastering this process, you can supercharge your understanding of how JavaScript handles concurrency, making you a more efficient and confident developer! 💪✨ #JavaScript #EventLoop #AsynchronousJavaScript #WebDevelopment #Frontend #CodingTips #LearnToCode

✨ How JavaScript Code Executes in the Browser ✨ When you run JS in the browser, two key phases happen: 1️⃣ Memory Allocation Phase (Creation) Variables are hoisted (declared but not assigned). Functions are stored in memory, ready to be invoked. 2️⃣ Execution Phase Code runs line-by-line inside the Call Stack. Synchronous code executes first, while asynchronous tasks (e.g., setTimeout, API calls) are sent to Web APIs. Once async tasks complete, the Event Loop moves them to the Call Stack if it's empty. #JavaScript #Frontend #WebDevelopment #namastejavascript #akshaySaini #linkedin #connections

You ever wondered how JavaScript manages to stay responsive despite being single-threaded? It's all thanks to some clever mechanisms working behind the scenes, and this mechanism consist of • Event Loop: It's allows JavaScript to handle asynchronous tasks without breaking a sweat. It ensures that tasks run smoothly, giving the impression of multitasking. • Call Stack: Think of this as JavaScript's to-do list. Functions are added when called and removed once completed. If something takes a while, it waits its turn. • Web APIs: These are like JavaScript's helpers, handling things like timers, DOM events, or HTTP requests. They take over tasks that would otherwise clog up the call stack. • Callback Queue: After a Web API completes a task, it adds the callback function to this queue. It's basically a line-up of tasks waiting to be processed. • Event Loop (Again): The event loop keeps an eye on the call stack. Once it's clear, it moves the next task from the callback queue to the call stack.

Happy Friday, all! Today I setup file path aliases for the #reactnative project I'm working on. Aliases can simplify the require/import paths in your project. Instead of importing something using a complex relative path like "../../../assets/my-image.png", you can use a simpler path like "~Assets/my-image.png". This has been especially nice in a larger, more structured project where components and screens are stored in their own designated folders. I achieved this by using the #babel plugin, babel-module-resolver. I specified the root directory, defined the desired aliases, and listed the file extensions that required handling in my babel config file. After that, I updated all of the complicated import paths to use the alias. Which was a lot, like 140 files 😮 VSCode's replace all instances tool saved the day for me there. That's all from me. Have a great weekend everyone!   #reactnative #javascript #babel #codeinpublic

Hey everyone! Let's dive into a fundamental concept in JavaScript – handling asynchronous operations with async/await and promises. 1. Why need of async/await and promises? In JavaScript, we often encounter situations where we need to perform tasks asynchronously, like fetching data from an API or reading files. Promises and async/await are two powerful tools we use to manage these asynchronous tasks. 2. What's the Difference? (i). Promises: Imagine promises as a series of steps. Each step represents an asynchronous operation. We chain these steps together using .then() and .catch() to handle success and error cases. Promises are like a guide, leading us through each task one after the other. (ii). Async/Await: Now, async/await is like having an assistant who takes care of everything for us. With async functions and await keywords, we write asynchronous code that looks synchronous. It's like telling the assistant, "Wait until this task is done before moving on to the next one." It makes our code cleaner, easier to read, and less prone to "callback hell." 3. When to use each one? (i). Promises: Simple asynchronous tasks or when precise control is needed. (ii). Async/Await: Readability and simplicity are crucial, especially in complex projects. #JavaScript #AsyncAwait #Promises #WebDevelopment #FrontendDevelopment #JavascriptFundamentals #JavascriptBasics
