JavaScript Basics: First Code and Program

#Day15 Mastering Callbacks in JavaScript Today let’s talk on Callbacks a core concept for handling asynchronous operations in JavaScript. At Mentorship for Acceleration for backend track, I explored how callbacks allow functions to execute after tasks like timers, events, or API responses complete. I also saw firsthand why they can lead to “Callback Hell” if not managed well. Key Concepts Practiced: => Basic callback implementation with setTimeout() => Using callbacks with array methods (.map(), .forEach(), .filter()) => Named vs anonymous callback functions => Understanding the limitations of nested callbacks Callbacks have sharpened my understanding of asynchronous programming and prepared me for cleaner patterns like Promises.

Most people “learn” JavaScript. Few actually understand it. After completing “Namaste JavaScript” by Akshay Saini 🚀, I realised : 👉 Hoisting isn’t magic 👉 Closures aren’t confusing 👉 The Event Loop isn’t scary It’s all about understanding the engine behind the code. This course helped me shift from: ❌ Copying code ➡️ Thinking like a developer Now the real journey begins — building, failing, and improving. If you're learning JavaScript, don’t rush. Depth > speed. #JavaScript #Programming #LearningInPublic #WebDev #AkshaySaini

Work in progress 💻 Deep in the code today, building out new functionality for Scrimba Advance JavaScript. Sometimes the best commits are the ones that say "promise" twice because that's exactly what clean, asynchronous code delivers. Those small, focused commits? That's where the real progress happens.

Async JavaScript is easier to understand when you stop thinking about “parallel code.” JavaScript still runs on a single main thread. What makes it feel non-blocking is the event loop, callback queue, and browser/runtime APIs working together. That is why setTimeout, fetch, and promises do not pause everything else. The big idea: async code gets scheduled first, then runs when the stack is ready. This infographic breaks that flow into the exact pieces that matter.

I have been recently having fun with Javascript and I recently create about 3hours plus video trying to explain concept like Object Oriented programming(OOP), Async/Await and Promise in Javascript. For the OOP part, I talked about the four features of OOP which: 1. Abstraction 2. Encapsulation 3. Inheritance 4. Polymorphism. I also talked about the three ways someone can implement OOP in Javascript which are through the class, Object.create and through contructor function. I also talked about the fact that Js does not really have true class but a synthetic sugar implementation over constructor function/prototypal inheritance. For the Async part, I talked about asynchronous Javascript, Event loop, Callback Queue, Promises, resolving promises and how to basically promisify an async functions.

Mastering strings is a foundational step in becoming efficient with JavaScript. From simple operations like charAt() and concat() to more practical methods like includes(), slice(), and replace(), understanding string methods can significantly improve how you manipulate and handle data in real-world applications. What looks basic at first often becomes powerful when building dynamic user interfaces, validating inputs, or processing text-heavy data. If you're learning or refining your JavaScript skills, take time to truly understand these methods — not just memorize them. The difference shows in how clean and efficient your code becomes. Consistency in the basics is what separates average developers from excellent ones. #JavaScript #WebDevelopment #Programming #Coding #FrontendDevelopment #TechSkills #LearnToCode #SoftwareDevelopment

Ever wondered why JavaScript shows “undefined” even before a variable is assigned? 🤯 console.log(a); var a = 10; At first glance, this feels confusing… But the answer lies in one powerful concept: 👉 Execution Context Here’s what actually happens behind the scenes: ⚡ When JavaScript runs your code, it creates an Execution Context ⚡ In the memory phase, variables are hoisted → initialized as undefined ⚡ In the execution phase, code runs line by line and values get assigned I made a short video explaining the basics—would love your feedback 🙌 #javascript #webdevelopment #frontend #programming #coding #developers #learntocode #100daysofcode

🚀 Today’s JavaScript Learning — DOM Stopwatch Project Today I worked on building a Stopwatch using JavaScript DOM. At first, the code was not working properly. The Stop button issue, event handling mistakes, and timer logic took me nearly 2 hours to debug. But finally I understood: ✅ DOM element selection ✅ EventListeners ✅ setInterval & clearInterval ✅ Debugging real errors ✅ Logical thinking improvement This small project taught me an important lesson: 👉 Programming is not about writing code fast — it’s about understanding problems patiently. Every mistake helped me learn deeper JavaScript concepts.
