npm vs npx: Node.js dependency management

Just published a new blog post on NPM and Package Management It covers how npm helps manage dependencies, install libraries, and streamline development in Node.js projects. I’ve also explained key concepts and practical use cases to make package management easier to understand. If you're working with Node.js, this is a must know topic!

Most people think the Event Loop just "manages async code." It actually plays favourites. I assumed every callback waited in the same line. Turns out, there are two queues — and they don't get equal treatment. The moment the call stack goes empty, the Event Loop doesn't just grab the next available function. It checks the Microtask Queue first — always. 𝐏𝐫𝐨𝐦𝐢𝐬𝐞𝐬 𝐚𝐧𝐝 𝐟𝐞𝐭𝐜𝐡() 𝐜𝐚𝐥𝐥𝐛𝐚𝐜𝐤𝐬 𝐥𝐢𝐯𝐞 𝐡𝐞𝐫𝐞. 𝐓𝐡𝐞𝐲 𝐜𝐮𝐭 𝐭𝐡𝐞 𝐥𝐢𝐧𝐞, 𝐞𝐯𝐞𝐫𝐲 𝐬𝐢𝐧𝐠𝐥𝐞 𝐭𝐢𝐦𝐞. Regular callbacks — button clicks, setTimeout — wait in the Callback Queue. They only get their turn once the Microtask Queue is fully drained. So the hierarchy is clear: → Call Stack executes → Microtask Queue gets priority when stack empties → Callback Queue runs only after microtasks are done One event loop. Two queues. One clear winner. Next time your async code behaves unexpectedly — check which queue it's sitting in. 🔍 → Agree or disagree?

Just published a deep dive into how V8 handles arrays under the hood 🚀 Key takeaway: not all arrays are equal. Packed arrays (SMI/Double) and TypedArrays are highly optimized, while holey and mixed arrays introduce hidden performance costs due to extra checks and de-optimizations. If you're writing performance-critical JavaScript, these low-level details *matter more than you think*. I’ve also included a benchmark to see the differences yourself 👇 https://lnkd.in/gsxGFNZv #JavaScript #V8 #Performance #NodeJS #Programming

Most developers get this WRONG 😅 What will be the output? console.log(1); setTimeout(() => console.log(2), 0); Promise.resolve().then(() => console.log(3)); console.log(4); 👇 Drop your answer before checking Understanding Event Loop = Next Level JavaScript 🚀 #JavaScript #CodingChallenge #FrontendDeveloper #TechCommunity #Programming #DevelopersIndia #LearnJS

A React component is a function which returns JSX. When you use that component inside another component, the React creates an element. <Ali /> refers to element of Ali component. So, when React sees <Ali /> it gets it's JSX and internally call React.createElement with details of Ali component such as props, key and children. React.createElement creates an object which is basically description of what needs to be rendered. Then React adds that to the virtual DOM and gets added to real DOM. Tried my best to simplify this concept. Thinking of writing a blog on it. You can subscribe to my newsletter to read in-depth. link in comment. #react #javascript #frontend #programming
