Revisiting JavaScript Fundamentals for Deeper Understanding

I wasted months watching JavaScript tutorials. It felt productive… But I wasn’t actually improving. The moment I started building projects, everything changed. So I made this: 10 JavaScript projects that can actually help you get hired 👇 [https://lnkd.in/gvUz5MYz] If you're stuck in tutorial hell, this might help. #javascript #webdevelopment #coding #100DaysOfCode

Implemented Selection Sort in JavaScript, where the smallest element is selected in each iteration and placed at its correct position. A simple yet effective way to understand sorting fundamentals and in-place operations. #JavaScript hashtag#DSA hashtag#Algorithms hashtag#Coding hashtag#WebDevelopment

Ever wondered why changing employee1 also changes employee in JavaScript? 🤯 It’s the classic Reference Trap—objects are stored in the heap, and the = operator only copies the reference, not the object itself. In my latest video, I break down how memory references work and why mastering Pass by Reference is key to writing bug-free code. 👉 Watch the full explanation and level up your JavaScript skills! 🎬 #JavaScript #CodingTips #WebDevelopment #ProgrammingConcepts

JavaScript becomes a different language the moment you realize this: 👉 Functions are not just reusable blocks… they are values. And once you understand that, concepts like callbacks and higher-order functions stop feeling confusing and start feeling natural. In this video, I’ve broken it down step by step: How values behave in JavaScript How objects behave Why functions behave the same way (and why that matters) From there, everything builds logically: ✔ Passing functions as arguments ✔ Returning functions from functions ✔ What exactly a callback is ✔ What a higher-order function is ✔ How this leads to more flexible and reusable code No jargon. No unnecessary complexity. Just a clear, practical approach to a core JavaScript concept. 🎥 Watch here: https://lnkd.in/gM8ibZ6M This is Part 1 — next, we’ll explore how this shows up in real code with: setTimeout, forEach, map, filter #JavaScript #WebDevelopment #FrontendDevelopment #Programming #Coding #LearnToCode #JavaScriptDeveloper #SoftwareDevelopment #Developers #CodingJourney #TechEducation #Hosiyar #JS

🚀 From Confusion → Clarity (JavaScript Learning Moment) Today I finally understood one of the most confusing topics in JavaScript: 👉 "this" keyword with Arrow Functions vs Regular Functions At first, it made ZERO sense 😵 But after practicing, here’s what clicked: ✅ Regular functions → "this" depends on how they are called ✅ Arrow functions → don’t have their own "this", they inherit it from parent scope 💡 This small difference can completely change your output — especially inside "setTimeout()" and callbacks! Sharing this because I know many beginners struggle with this (just like I did 🙌) 📍 Still learning. Still growing. One step closer to becoming a Full Stack Developer. #JavaScript #WebDevelopment #CodingJourney #FullStackDeveloper #100DaysOfCode #LearningInPublic

One important question when learning JavaScript: 👉 How are we able to run JavaScript without internet? Simple answer 👇 Because browser itself can run JavaScript. Every browser has something called a JavaScript Engine. 👉 Example: Google Chrome uses V8 Engine So what happens? 👉 You write JavaScript 👉 Browser reads it 👉 Engine executes it That’s why: ➡️ You can run code in DevTools Console ➡️ You can run code using local files ➡️ No internet is required 👉 VS Code is just for writing code 👉 Browser (with engine) is what actually runs it This is a small concept… But very important to understand how things work. #javascript #automationtesting #qa #learning

A quick look at some powerful TypeScript features: • Generics (with constraints) • Conditional & Mapped Types • typeof & keyof These concepts make it easier to write flexible, reusable, and maintainable TS code.

Continuing my Frontend revision, sharing my handwritten notes on JavaScript concepts. While learning JavaScript, I realized how important it is to understand how strings and arrays actually work. These cover string methods, method chaining, arrays, array methods, and basic operations on arrays. Sharing in case it helps anyone learning JavaScript fundamentals.

In this Postman Tutorial, we will learn about variables in JavaScript. In order to do API test automation with Postman we need to learn JavaScript for API testing. As Postman tool supports JavaScript so we can write automated API tests in Postman using JavaScript. https://lnkd.in/drHCD477 #PostmanTutorial #javascript #javascriptforbeginners #PostmanAPITesting #ApiTesting #API #apiautomation #RcvAcademy #SoftwareTestingMentor
