Learning JavaScript Fundamentals: Variables and Control Flow

Started my journey with automation and programming thinking strongly typed languages already solved many problems. In languages like Java, type safety is already built in. You define a type, and the compiler protects you from many mistakes before the code even runs. But when I started exploring Playwright with TypeScript, one question came to my mind: "If Java already has type safety, why do we need TypeScript again?" Then the learning clicked. 💡 TypeScript is not replacing strongly typed languages. Instead, it brings type safety into the JavaScript ecosystem. For large automation frameworks, this brings several advantages: ✔ Catching errors at compile time ✔ Better IDE auto-completion ✔ Safer code refactoring ✔ Cleaner and maintainable automation code Playwright supports multiple languages like Java, Python, JavaScript, and TypeScript, and each team chooses what fits their ecosystem best. At the end of the day, the key lesson is simple: Use the right tools for the right problem. And keep learning — because technology never stands still. 🚀 #AutomationTesting #TestAutomation #Playwright #TypeScript #Java #SDET #SoftwareTesting #QualityEngineering #AutomationEngineer #TechLearning #LearningJourney #QACommunity #AutomationFramework #SoftwareQuality #TestEngineering

Closures in JavaScript are a powerful concept that allow functions to retain access to their lexical scope, even after execution. They are widely used for data encapsulation, maintaining state, and building modular, maintainable code in modern applications. Understanding closures reflects strong command over core JavaScript fundamentals. #JavaScript #Closures #FrontendDeveloper #WebDevelopment #SoftwareEngineering #CleanCode #Programming #DeveloperSkills #TechCareers #ModernJavaScript

I wrote a small JavaScript example to practice callbacks and asynchronous programming. The code simulates fetching a user’s data step by step: first the ID, then the name, then the surname.

After years of building with Java and TypeScript, I realized something: I had become too comfortable with Garbage Collectors and abstractions. I felt a bit disconnected from how things actually work under the hood, specifically when it comes to memory management and system resources. I decided to change that. I’ve started a journey to dive into low-level programming, and I picked Zig as my tool of choice. To make the learning process real and painful (in a good way), I’m building a custom HTTP web framework from scratch: zserver. This isn't about reinventing the wheel for production use; it's about relearning the fundamentals. I want to understand every byte I allocate and deallocate. I’m still very early in the process, but I’m open sourcing it. If you’re into systems programming or just want to see how I struggle with pointers and allocators, feel free to take a look! 🔗 https://lnkd.in/dAB256yK #ZigLang #Zig #LowLevel #BackendDevelopment #SystemDesign #OpenSource

🚀 Day 59 of #100DaysOfCode Today I worked on a classic problem: Converting Time into Words (C Programming) ⏰ It sounds simple — but it really tests your: ✅ Conditional logic ✅ Edge case handling ✅ String formatting ✅ Problem understanding For example: 5:47 → thirteen minutes to six 3:00 → three o' clock 7:15 → quarter past seven This problem reminded me that: 👉 Clean logic > Complex logic 👉 Edge cases matter a lot 👉 Small problems improve big thinking As a developer, mastering fundamentals in C strengthens problem-solving skills for any language — whether it’s JavaScript, Java, or backend development. Consistency is the real power. 59 days done. Still building. 💪 #Day59 #100DaysOfCode #CProgramming #ProblemSolving #CodingJourney #DeveloperGrowth #Consistency

Because JavaScript does not follow traditional class-based OOP like Java or C++. Instead, it uses a prototype-based inheritance model. In this video, I explain: • Why JavaScript OOP is different • Prototype vs Class concept • How JavaScript actually creates objects behind the scenes • Why many developers get confused with JavaScript OOP If you want to become a better JavaScript / Full Stack developer, understanding this concept is very important. 🎥 Watch the full video here: https://lnkd.in/dyNPYRMu What confused you the most when learning JavaScript OOP? #javascript #oop #javascriptdeveloper #webdevelopment #programming #softwaredeveloper #nodejs #reactjs #coding #learnjavascript #frontenddevelopment #developercommunity

🚀 JavaScript Fundamentals Series — Part 9 Once you understand objects, the next step is Object-Oriented Programming. OOP helps structure complex programs using: • Classes • Objects • Encapsulation • Reusable code In this guide I explain how JavaScript implements OOP and how it helps organize applications.

Callbacks in JavaScript are fundamental for handling asynchronous operations and controlling execution flow. They allow functions to be passed as arguments and executed later, enabling efficient handling of tasks like API calls, events, and data processing. Understanding callbacks is essential for mastering JavaScript’s core behavior. #JavaScript #Callbacks #AsyncJavaScript #FrontendDeveloper #WebDevelopment #SoftwareEngineering #Programming #DeveloperSkills #CleanCode #TechCareers
