React Components Revision Notes and Examples

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

The weirdest value in JavaScript — explained fast. 😈 This is the edited version. NaN is not a number… And it’s not equal to itself either. A quick JS concept every developer must know. #CodeBreakDev #JavaScript #NaN #JSConcepts #InterviewPrep

Practicing React hooks with a simple project: a button that prompts for name and age, stores them in state, and renders dynamically #ReactJS #JavaScript #CodingJourney

100 identical requests. 1 expensive DB call! I wrote about request collapsing and how to implement it in NestJS using an interceptor + decorator. https://lnkd.in/dJZK859c #javascript #nestjs #requestsandlimits

This is a fantastic topic! 💡 I try to bridge the gap using a CI pipeline as a DevOps analogy. I think of a build where environment variables get "baked" into the image. Now, even when I deploy to Prod later and overlay the baked variable in Kubernetes, the container stubbornly remembers the values from its creation time. (Not recommended by the way 😂) So a Closure is a function that captures a snapshot of its definition scope (Build Time) and carries it into the execution scope (Run Time). Does anyone else use infrastructure patterns to understand coding concepts? 😉 #JavaScript #DevOps #BonnConsulting

DAY 22 OF POSTING REACT CONTENT ⚛️ WHAT ARE ES MODULES? 🤔 Modern JavaScript uses ES Modules to split code into separate files. Instead of writing everything in one file, we can: 👉 export something from one file 👉 import it into another file React heavily depends on ES Modules. Every component you create is usually exported and imported somewhere else. #ReactJS #JavaScript #ESModules #FrontendDevelopment #LearnInPublic #WebDevelopment #CodingJourney

Writing less code in React, but thinking more about structure and edge cases. That’s where most bugs hide. #ReactJS #FrontendDevelopment #JavaScript #CleanCode #SoftwareEngineering #DeveloperLife #WebDevelopment

React performance tip that actually matters 🚀 Most re-render issues come from: ❌ Passing new objects/functions in props ❌ Unstable dependencies ❌ Unnecessary state Fix it with: ✅ memoization (when needed) ✅ stable handlers ✅ derived state 💬 Have you debugged re-renders before?
