Async/Await simplifies working with promises, making asynchronous code easier to read and manage. Here's a quick tutorial: Use the async keyword before a function to declare it asynchronous. Use the await keyword to pause the execution until a promise resolves or rejects. async function fetchData() { try { const response = await fetch('https://lnkd.in/dz48DrYF'); const data = await response.json(); console.log(data); } catch (error) { console.error('Error fetching data:', error); } } fetchData(); This structure is cleaner than chaining .then() calls!

⏳ Async/Await: Writing Asynchronous Code Synchronously ⏳ async/await makes asynchronous code easier to read and write by allowing us to use a synchronous-looking syntax. Example: Async/Await function fetchData() { return new Promise(resolve => { setTimeout(() => { resolve("Data fetched!"); }, 2000); }); } async function getData() { const data = await fetchData(); console.log(data); // Output after 2 seconds: Data fetched! } getData(); Using async/await improves the readability and manageability of asynchronous code. #JavaScript #AsyncAwait #WebDevelopment #Frontend

🧵 Promises vs Async/Await - What’s the Difference? Both handle async code, but how do they differ? Let’s find out! 𝗣𝗿𝗼𝗺𝗶𝘀𝗲𝘀 are objects, representing the eventual completion (or failure) of an async operation. Example: ``` fetch('api/data') .then(response => response.json()) .then(data => console.log(data)) .catch(err => console.error(err)); ``` 𝗔𝘀𝘆𝗻𝗰/𝗔𝘄𝗮𝗶𝘁: simplifies promises by allowing you to write async code in a synchronous style: ``` async function fetchData() { try { let response = await fetch('api/data'); let data = await response.json(); console.log(data); } catch (err) { console.error(err); } } ``` Here are the 👇 𝗞𝗲𝘆 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲𝘀: - Promises use `.then()` and `.catch()` chaining. - Async/await looks cleaner, especially with complex promise chains. - Both handle async logic, but async/await can make your code more readable. 👓 - Which one do you prefer?

𝗛𝗲𝗹𝗹𝗼 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿𝘀 / 𝗖𝗼𝗱𝗲𝗿𝘀, In our day-to-day development process, many of us create bundles without knowing the best practices that can help reduce costs and enhance application performance. How many of you are familiar with 𝗧𝗿𝗲𝗲 𝗦𝗵𝗮𝗸𝗶𝗻𝗴? 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗧𝗿𝗲𝗲 𝗦𝗵𝗮𝗸𝗶𝗻𝗴? With tree shaking, we can reduce the bundle size by eliminating dead code. Tree shaking is aimed at removing unused code from a 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 bundle. Bundlers can automatically detect dead code, to exclude this code from the final bundle. 𝗟𝗲𝘁'𝘀 𝘂𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱 𝗶𝘁 𝘄𝗶𝘁𝗵 𝗮𝗻 𝗲𝘅𝗮𝗺𝗽𝗹𝗲: If two methods are exported from the input.js file, namely validateInput and formatInput, but we're only importing validateInput, the bundler will ensure that the formatInput method won't be included in the final bundle. // 𝗶𝗻𝗽𝘂𝘁.𝗷𝘀 export function validateInput(input) { const isValid = input.length > 10; return isValid; } export function formatInput(input) { const formattedInput = input.toLowerCase(); return formattedInput; } // 𝗶𝗻𝗱𝗲𝘅.𝗷𝘀 import { validateInput } from "./input"; const input = document.getElementById("input"); const btn = document.getElementById("btn"); btn.addEventListener("click", () => { validateInput(input.value); }); After tree shaking, the final bundle won't include the formatInput function as it's not referenced in the code. #TreeShaking #JavaScriptOptimization #CodeOptimization #WebDevelopmentTips #PerformanceBoost #FrontendDevelopment #JavaScriptPerformance #BundleOptimization #CleanCode #DevelopmentBestPractices #ReduceBundleSize #EfficientCoding #CostEffectiveDevelopment #ModernJavaScript

More Important To Know The Benefits From These Concepts👀: ✅𝗘𝘃𝗲𝗻𝘁 𝗟𝗼𝗼𝗽: -The engine that allows JavaScript to execute asynchronous code (like timers, network requests) while being single-threaded. It manages when asynchronous tasks get added back to the main thread for execution. ✅𝗖𝗮𝗹𝗹𝗯𝗮𝗰𝗸: -A function passed to another function, executed after an asynchronous task is completed. While useful, callbacks can lead to messy, nested code ("callback hell"). ✅𝗣𝗿𝗼𝗺𝗶𝘀𝗲: -An object that represents a future result of an asynchronous task. It can be either fulfilled (successful) or rejected (error). Promises allow chaining operations to make the code cleaner. ✅𝗔𝘀𝘆𝗻𝗰/𝗔𝘄𝗮𝗶𝘁: -A more readable way to handle Promises, making asynchronous code look synchronous. async functions use await to pause execution until the Promise resolves, making the flow easier to understand. #Javascript #FrontEndEngineering #CallbackPromiseAsyncAwait

🚀 𝐌𝐚𝐬𝐭𝐞𝐫𝐢𝐧𝐠 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐂𝐥𝐨𝐬𝐮𝐫𝐞𝐬 𝐟𝐨𝐫 𝐃𝐚𝐭𝐚 𝐏𝐫𝐢𝐯𝐚𝐜𝐲 𝐚𝐧𝐝 𝐒𝐜𝐨𝐩𝐞 𝐂𝐨𝐧𝐭𝐫𝐨𝐥! 🚀 Closures are powerful tools in JavaScript. They let functions access variables outside their immediate scope. The example shows how closures can create private, persistent data across calls. This pattern is super useful for: 🔹 Data encapsulation 🔹 Stateful functions 🔹 Managing scopes in asynchronous callbacks By leveraging closures, we can build more secure and organized code. #JavaScript #Closures #WebDevelopment #Coding #DevSouq
