Mastering JavaScript before React for a smoother workflow

🧠 Why JavaScript Fundamentals Matter Frameworks like React and Next.js are powerful, but they are built on top of JavaScript. Understanding concepts like: • Closures • Promises • Event Loop • Scope can make a huge difference in writing better and more efficient code. Strong fundamentals always make learning new technologies easier. #JavaScript #FrontendDeveloper #Coding

JavaScript felt complete, until I tried TypeScript. I just started the TypeScript module in Melvyn Malherbe's NextFullStack course. I thought it was just "JavaScript with extra steps". It's actually JavaScript with superpowers. I'm still learning, It's just the beginning, but I already can't imagine going back to plain JavaScript. If you use TypeScript, what's the one thing you wish you knew when you started? #TypeScript #JavaScript #LearnInPublic #FrontendDev #NextJS

JavaScript is fast and flexible. TypeScript catches errors before they happen. Small projects? JS is perfect. Big projects? TS is a lifesaver. Which one do you reach for first? #JavaScript #TypeScript #WebDevelopment #CodingLife

While learning JavaScript, I wanted to understand the actual flow of asynchronous operations. This simple diagram shows the sequence from fetch() to Promises, async/await, error handling with try/catch, and finally organizing code using ES Modules. I learned these concepts from Devendra Dhote bhaiya and tried to visualize the flow in a simple way. Breaking concepts into small visual steps makes asynchronous JavaScript much easier to understand. #javascript #webdevelopment #frontend #learninginpublic #sheryians

Many beginners think querySelector() in JavaScript and useRef() in React do the same thing. But React uses a Virtual DOM, so direct DOM manipulation can break React’s flow. That’s why useRef() gives controlled access to the DOM while keeping React’s architecture intact.

JavaScript is indeed a very wierd language. Maybe because it was developed in just 10 days to add dynamic behaviour to otherwise static HTML pages. The deeper you dive into JavaScript, the wierder it becomes. 1. Higher Order Functions -> Functions can be passed as arguments and returned from other functions. 2. Closures -> The inner function still remembers its neighbouring variables even after the outer function completes execution. 3. Callbacks -> A function can be passed as an argument to another function, to be executed later (usually after some async operation completes). 4. Callback Hell -> If multiple such callbacks are nested together, you are stuck in this 'Pyramid of Doom' 5. Promises -> An object which represents the current state of an asynchronous operation that can be returned from async functions to avoid the callback hell while chaining sequential async steps. 6. async / await -> More elegant way to make asynchronous code look and feel synchronous, but still make it non-blocking. And honestly we have not even started OOPS in JavaScript. The so called 'Prototypal Inheritance' and the binding of 'this' keyword which is the most confusing part of JS makes this language very difficult to master. But the good news is that you dont have to study everything. Instead you have to study just enough concepts to get the work done. For front end frameworks like React and Vue.js just the functional programming concepts mentioned earlier is sufficient. Take a look at this video where Keerti Purswani from Educosys explains these concepts in the most simplest of ways. It really helped me set my basics right. https://lnkd.in/gJWgMQf2 Here is the link to my GitHub repo where you can find code which I did while following the tutorial. https://lnkd.in/gzSacyg5 #ReactJS #VueJS #Angular #NextJS #JavaScript #JS

🚀 JavaScript Nuggets for Developers Every JavaScript developer should be familiar with these powerful “nuggets” — small but impactful tricks that can significantly improve your coding efficiency and problem-solving skills. I’ve recently learned and started applying these techniques, and they’ve already made a noticeable difference in how I write and understand JavaScript. I highly recommend that fellow developers take the time to explore and master these concepts — they may be small, but their impact is huge. credits - Javascript mastery #JavaScript #WebDevelopment #CodingTips #FullStackDevelopment #DeveloperJourney

When I first started learning #JavaScript, I made a lot of mistakes. Not because JavaScript is hard — but because I was learning it the wrong way. If you’re starting your JavaScript journey, try to avoid🛑 these 3 common mistakes: 1️⃣. Jumping straight into frameworks** Many beginners start with #React, #Next.js, or other frameworks without understanding core JavaScript. Frameworks are built **on top of JavaScript**. If your basics are weak, everything will feel confusing. Start with fundamentals: Variables, Functions, Arrays, Objects, Closures, Promises, and the DOM. 2️⃣. Watching videos tutorials without mentorship ** Watching 10 hours of tutorials feels productive… but it’s not the same as practising Real learning happens when you: * write code * break things * debug errors * build small projects Code along. Then try building the same thing 3️⃣. Trying to memorize everything** You don’t need to remember every method or syntax. Great developers don’t memorize everything. They understand concepts and know **how to find answers**. Focus on understanding *why things work*, not just *how to write them*. If you avoid these three mistakes early, your JavaScript journey becomes much easier.
