Day 13 – Node.js Understanding HTTP Methods Today I implemented basic handling of HTTP methods using the built-in http module. By checking req.method, we can differentiate between GET and POST requests. Understanding this is essential before moving to REST APIs and Express. Next: Handling POST request body in pure Node.js. #NodeJS #BackendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering

JavaScript Promise.all() vs Promise.allSettled(): Promise.all() → Fails if ANY promise rejects Promise.allSettled() → Waits for ALL, returns status of each For critical operations: Use Promise.all() For non-critical batch operations: Use Promise.allSettled() Know the difference. Use wisely. #JavaScript #AsyncJS #CodingTips

I learned about the rest operator in JavaScript. When a function can receive an unknown number of arguments, we can use the rest operator (...). We define the known parameters first, and then use ... with one parameter to collect the remaining arguments. All extra arguments are stored inside that rest parameter as an array. A simple but powerful feature that makes functions more flexible. #JavaScript #ES6 #RestOperator #Functions #WebDevelopment #LearningJourney

Schema validation is a critical part of building secure and reliable APIs. Here’s a side-by-side comparison of Express Validator, Joi, and Zod with practical examples to help you understand the differences in syntax and structure. Which one do you prefer in your Node.js projects — Express Validator, Joi, or Zod? #NodeJS #BackendDevelopment #JavaScript #WebDevelopment #APIs

Memoization is a powerful tool but misusing it creates: • Extra memory usage • More dependency comparisons • Harder debugging • Zero real performance gains Optimization without profiling is just assumption. Use React DevTools. Find the real bottleneck. Fix what actually matters.

frameworks and libraries is all about syntax, the real deal is knowing what powers them... useEffect and useState are dangerous syntax to someone who doesn't understand how window loaded and DomContent event listeners work in pure javaScript... Axios is great but if you dont know how the fetch API works, the you would struggle to undertstand how the browser handles http errors... Knowing the fundamentals isn't about going back to the stone age, its what you need to build with confidence. #reactjs #frontend #javaScript

Server Actions feel powerful — almost magical ✨ But many developers are using them unsafely. Let’s break down the common mistakes and the right way to use them. #NextJS #ReactJS #WebDevelopment #FrontendTips #JavaScript

A highly practical article on building bulletproof React components. I know that it sounds trivial but there are some good tips. Give it a read https://lnkd.in/dNqCsk65 #React #JavaScript

Day 12 – Node.js Handling Routes Without Express Today I implemented basic routing using the built-in http module. By checking req.url, we can manually handle different routes and send appropriate responses. This helps understand how routing works internally before using frameworks like Express.
