Understanding Object.create() in JavaScript: A Coding Task

📝 JavaScript Interview Coding Task Question – Day 73 Look at this code snippet 👇 ✅ Answer & Explanation: Parent constructor Child constructor Hello from Parent Hello from Child 1️⃣ The super keyword in classes is used to call methods on the parent class. 2️⃣ In the Child class, the constructor calls super() → this triggers the Parent constructor first before accessing this. 3️⃣ When child.sayHello() is called, it uses the overridden method in Child, but inside it, super.sayHello() invokes the parent’s version. 4️⃣ The output shows how inheritance chains both constructors and methods, combining parent and child logic. ✨ Tip: 👉 Always call super() before using this in a subclass constructor. 👉 super.method() helps reuse parent logic without rewriting it. #100DaysOfCode #JavaScript #Frontend #WebDevelopment #CodingInterview #JSClasses #Inheritance #DailyCoding #LearnInPublic #kirantechnophile

Yesterday, during an interview, I was asked about JavaScript closures. Honestly, I couldn’t explain it properly at that moment. 😅 Afterwards, I took some time to explore it, write some code, and finally understood that a closure is more than just a function — it’s a function that retains access to variables from its outer scope, even after that outer function has finished executing. This small but powerful concept really helped me think more clearly in JavaScript, especially when dealing with data privacy and functional programming. 💡 Key takeaway: Professional growth isn’t just about knowing the right answers—it’s about learning. A small failure often opens the door to bigger learning opportunities. Have you practiced closures? What’s your favorite example? 📝 #JavaScript #Closure #LearningFromExperience #WebDevelopment #ContinuousLearning

## 🚀 **Top 10 JavaScript Concepts Every Developer Should Know!** 💛 JavaScript is the heart of web development — mastering its core concepts makes you a real problem-solver! Let’s quickly revisit some powerful fundamentals 👇 --- ### 🧩 1️⃣ **Variables (`var`, `let`, `const`)** * `var` → Function-scoped * `let`, `const` → Block-scoped * Use `const` when the value won’t change. ```js let name = "Vijaya"; const age = 25; ``` --- ### ⚡ 2️⃣ **Hoisting** Variables and functions are moved to the top of their scope before execution. ```js console.log(x); // undefined var x = 5; ``` --- ### 🌀 3️⃣ **Closures** A function “remembers” the variables from its parent scope — even after the parent is gone! ```js function outer() { let count = 0; return function inner() { count++; console.log(count); }; } const counter = outer(); counter(); // 1 counter(); // 2 ``` --- ### 🧠 4️⃣ **Promises & Async/Await** Handle asynchronous code neatly. ```js async function getData() { const data = await fetch('https://api.example.com'); console.log('Data loaded!'); } ``` --- ### 🧮 5️⃣ **Array Methods** Powerful one-liners for clean code: * `map()` – transform data * `filter()` – filter elements * `reduce()` – combine values ```js let nums = [1,2,3]; let doubled = nums.map(n => n*2); ``` --- ### 🔁 6️⃣ **Callback Functions** A function passed as an argument to another function. ```js function greet(name, callback) { callback(`Hello ${name}`); } greet("Vijaya", console.log); ``` --- ### 🧱 7️⃣ **Objects & Destructuring** Extract values easily: ```js const user = {name: "Vijaya", age: 22}; const {name, age} = user; ``` --- ### 🔥 8️⃣ **ES6 Features** Modern JavaScript = cleaner syntax! ✅ Template literals ✅ Arrow functions ✅ Spread & Rest operators ✅ Modules ```js const arr = [1, 2]; const newArr = [...arr, 3]; ``` --- ### 🧭 9️⃣ **Event Loop** JS is single-threaded but handles async tasks smartly. 📚 Tasks go to the callback queue and execute when the main thread is free. --- ### 💥 🔟 **DOM Manipulation** Make your webpage dynamic! ```js document.getElementById("demo").innerText = "Hello JS!"; ``` --- ### ✨ **Final Thought** > “Knowing syntax is easy — understanding concepts makes you a real developer.” Keep practicing, keep building 💪 #JavaScript #WebDevelopment #CodingJourney #LearnWithMe #FrontendDeveloper #LinkedInLearning #100DaysOfCode Ajay Babu Sappa 10000 Coders sanjeev ch Manivardhan Jakka

👇 💻✨ JavaScript Practice Update! Today I worked on a task using the prompt() and document.write() methods to take multiple inputs from the user and display employee details dynamically on a web page. 🧠 Task Overview: Take inputs such as Employee ID, Name, Email, Phone Number, Salary, Experience, Joining Date, Location, and Designation using prompt(). Display all details in a formatted way using document.write(). ✅ Output Example: Displays all employee details entered by the user directly on the document. 🧩 This exercise helped me understand how to: Capture user input in JavaScript Display formatted data using DOM methods Work with basic string concatenation #JavaScript #FrontendDevelopment #WebDevelopment #LearningJourney #Coding #HTMLCSSJS #Programming #JS #CodingJourney #10000coders #MeghanaM #SpandanaChowdary

🚀 JavaScript Methods You Must Know as a Developer JavaScript methods are the building blocks that make coding efficient and powerful. From working with strings and arrays to handling objects, these methods simplify our daily development tasks. Some must-know JS methods include: 📌 map(), filter(), reduce() for arrays 📌 toUpperCase(), slice(), replace() for strings 📌 Object.keys(), Object.values() for objects Understanding these methods will help you write cleaner, faster, smarter code. #JavaScript #WebDevelopment #FrontendDevelopment #JavaScriptConcepts #JavaScriptDeveloper #LearnJavaScript #Coding #Programming #FrontendDeveloper

🔥 JavaScript Interview Series(15): Inside the JavaScript Engine: V8 & SpiderMonkey Explained When preparing for advanced JavaScript interviews, understanding how JavaScript engines like V8 (used in Chrome and Node.js) and SpiderMonkey (used in Firefox) work internally can set you apart from average developers. These engines do more than just interpret JavaScript — they compile, optimize, and execute your code using complex architectures and Just-In-Time (JIT) compilation techniques. Let’s dive into 10 real interview questions that test your understanding of JavaScript internals, performance, and optimization strategies. Focus Area: Execution model, JIT compilation Standard Answer: interpreter executes code line-by-line, translating JavaScript directly into bytecode and running it immediately. This is fast for startup but slow for long-running applications. A JIT (Just-In-Time) compiler, on the other hand, compiles frequently executed code (hot paths) into optimized machine code while the program is running, improving performance over time. V8 and SpiderMonkey both use a hybrid https://lnkd.in/gTagtBc4
