Managing multiple local projects with different ports can get messy quickly. Portless by Vercel Labs solves this by replacing ports with clean, named localhost URLs like api.myapp.localhost. No port conflicts, clearer tabs, and a smoother development workflow. #WebDevelopment #DeveloperTools #SoftwareDevelopment #JavaScript #DevExperience https://lnkd.in/gJGABYB3

The spread operator looks like this: ... The rest operator looks like this: ... They're identical. But they do opposite things. Spread = Expands outward Rest = Collects inward I wrote a detailed guide breaking down both with real examples: Array & object spreading patterns Rest parameters & destructuring Practical use cases (React, APIs, function forwarding) Why context matters Simple rule: Use spread to unpack. Use rest to gather. 🔗 Read here: https://lnkd.in/gnMgH-zR More JavaScript fundamentals on Hashnode: https://lnkd.in/gAwxuryw Inspired by @Hitesh Choudhary @Piyush Garg @ChaiCode #JavaScript #ES6 #WebDevelopment

Day 14 #100DaysOfCode 💻 Today I learned Promise & Async/Await in JavaScript. Promise helps handle asynchronous operations like API calls. Async/Await makes code cleaner and easier to read. Example: function getData() { return new Promise((resolve) => { setTimeout(() => { resolve("Data received"); }, 1000); }); } async function fetchData() { const result = await getData(); console.log(result); } fetchData(); Now I can handle async code without messy callbacks 🚀 #JavaScript #AsyncAwait #Promise #WebDevelopment #CodingJourney #Akbiplob

Inconsistent syntax in a #React project almost cost me hours of debugging. In store.js, I used set-people, while in Home.jsx, I used set_people. It took a while to catch it. The problems is, after changing both to set_people, the store is now inconsistent since other cases in this switch statement use an underscore. I may change all to an underscore to keep them the same. This seems to be more common among developers than the dash when using storeReducer, despite camel case being most recommended in #JavaScript in general.

📌 Promises in JavaScript A Promise represents the eventual completion or failure of an asynchronous operation It has three states: pending, fulfilled, and rejected .then() handles successful outcomes .catch() handles errors Helps avoid callback hell and improves code readability 👉 Use case: API calls, asynchronous data handling #JavaScript #Promises #AsyncProgramming #WebDev #Coding

JavaScript is a single-threaded language, which means it executes one task at a time using the call stack. But it can still handle asynchronous tasks like API calls, timers, and promises. This happens because of the Event Loop. The Event Loop continuously checks if the call stack is empty. When it is empty, it takes tasks from the callback queue and moves them to the stack to be executed. Because of this system, JavaScript can run asynchronous operations without blocking the main thread, which makes web applications faster and more responsive. Learning the Event Loop helped me understand how JavaScript manages asynchronous code behind the scenes. #JavaScript #Coding #EventLoop #async

REST API Best Practices Every Dev Needs Building APIs that won't haunt you at 2AM 🔥 Here are 5 patterns that separate good devs from great ones: 1️⃣ Use nouns, not verbs — /users not /getUsers 2️⃣ Version your API — /api/v1/ saves future headaches 3️⃣ Plural resource names — /products not /product 4️⃣ Always HTTPS — never expose APIs over plain HTTP 5️⃣ Rate limit everything — protect from abuse And please… return the right status codes. 400 ≠ 500 🙏 A well-designed API is like a good joke — if you have to explain it, it's not that good. Save this for your next project! 🔖 #RestAPI #WebDevelopment #BackendDev #NodeJS #APIDesign #JavaScript #SoftwareEngineering #TechTips

🚀 Day 955 of #1000DaysOfCode ✨ How JavaScript Event Loop Works Behind the Curtains JavaScript looks simple on the surface — but under the hood, a lot is happening to make async code work smoothly. In today’s post, I’ve explained how the JavaScript Event Loop actually works behind the scenes, so you can understand how tasks are executed, queued, and prioritized. From the call stack to the callback queue and microtask queue, this concept explains why some functions run before others — even when the code looks sequential. Understanding the event loop helps you debug tricky async issues, avoid unexpected behavior, and write more predictable code. If you’re working with promises, async/await, or APIs, this is one of those concepts you must truly understand. 👇 What part of the event loop confuses you the most — call stack, microtasks, or callbacks? #Day955 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #CodingCommunity #AsyncJavaScript

A small but common mistake when working with asynchronous JavaScript: forgetting await. Everything in the code can look correct, the function is async, the logic makes sense, but without await, the result you expect never arrives when you need it. It’s a simple oversight, but it can cause confusing behavior when working with APIs or database calls. Sometimes the difference between a bug and a working feature is just one keyword. #JavaScript #AsyncAwait #SoftwareDevelopment #WebDevelopment #Debugging #DeveloperExperience

hi connections Day 16 of 30: Implementing a Promise Time Limit! Moving deeper into the Asynchronous section of my 30 Days of JavaScript on LeetCode. Today was about adding a "safety net" to our code. 🛠️⏳ The Goal: Wrap an async function so that if it takes longer than a specified time t, it immediately fails with a "Time Limit Exceeded" error. The Lesson: I used Promise.race() to pit the actual function against a custom timeout promise. This pattern is crucial for building resilient systems. Whether it's a web crawler or a high-traffic API, you never want one slow request to block your entire event loop. Control the time, control the performance! 💻🔥 #JavaScript #WebDevelopment #CodingChallenge #LeetCode #Day16 #SoftwareEngineering #AsyncJS #PerformanceOptimization
