JavaScript String Methods Cheat Sheet for Developers

Why does this print 4 4 4 4 in JavaScript? 🤯 A small setTimeout() + var question that teaches a big concept: closures, scope, and async behavior. When you understand why it happens, JavaScript starts making much more sense. #JavaScript #WebDevelopment #Programming #Coding #FrontendDevelopment #SoftwareEngineering #Developer #TechCommunity #LearnToCode #AsyncJavaScript #Closures #SetTimeout #100DaysOfCode #CodingTips #JavaScriptDeveloper

Most JavaScript problems aren’t about complexity. They’re about fundamentals. Common mistakes I still see: Using == instead of === Not understanding scope Poor async handling Callback hell Fixing these will improve your code quality instantly. Master the basics → everything else becomes easier.

If you're learning JavaScript, understanding functions is non-negotiable. These are the core types every developer should know: • Function Declaration • Arrow Function • Anonymous Function • Callback Function • IIFE (Immediately Invoked Function Expression) • Higher-Order Function • Constructor Function Most beginners jump into frameworks without mastering these basics — and that’s where problems start. Strong fundamentals = faster growth in development.

Master the most important JavaScript loops every developer should know 🚀 From basic iteration to clean and efficient coding — these loops are your foundation: • for • for...of • for...in • while & do...while • forEach() 💡 Pro Tip: Write cleaner code by choosing the right loop and avoiding unnecessary complexity. Start simple. Stay consistent. Level up daily. #JavaScript #WebDevelopment #FrontendDeveloper #CodingLife #LearnToCode #FullStackDeveloper #Programming #DeveloperLife #JS #TechSkills #CodeNewbie #100DaysOfCode #CodingJourney #SoftwareDevelopment #TechoSkills

Types of Functions in JavaScript... JavaScript offers multiple ways to write functions — each with its own use case: 💡 Knowing when to use each can make your code cleaner and more efficient. #JavaScript #WebDevelopment #Coding #Developers #LearnToCode

this in JavaScript looks simple… until it starts pointing to the wrong thing 😵 Same function, different outputs — just because of how it’s called. So what does this actually mean? 👉 It’s not about where the function is written 👉 It’s about who is calling the function In this blog, I’ve explained: What this really represents this in global context this inside objects and functions How calling context changes everything Kept it simple with clear examples (no unnecessary theory) ✨ 🔗 Read here: https://lnkd.in/dMkPffeA Would appreciate your feedback 🙌 #javascript #webdevelopment #programming #coding

30 Days JavaScript Challenge : Day 24 ✅ Today’s problem was about sorting an array using a custom function. Instead of directly sorting values, we use a function fn to decide the order — basically telling JavaScript how to compare elements. At first it feels simple, but it actually shows how powerful sorting can be when you control the logic: Sorting objects based on a property Sorting nested arrays Custom ranking based on conditions It’s one of those concepts that looks basic but is used everywhere in real projects. Slowly getting more clarity on how to write flexible and reusable logic in JavaScript. #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic
