💻 Day 41 Exploring Core JavaScript Concepts 🚀 Today’s class was full of core JavaScript learning and some deep insights about what it really means to think like a developer. 💡 We covered topics like: • Functions inside functions, First-class functions, and Higher-order functions • Closures how JS remembers variables even after execution • Arrays and Objects and methods like push(), pop(), splice(), sort(), shift(), unshift(), and more The best part was learning about the developer mindset understanding what today’s generation of developers truly need to focus on: 👉 Not just hard work, but smart work writing cleaner, logical, and efficient code. Each class is helping me connect the dots between concepts, logic, and real world thinking. Loving the process and learning something new every day with Sheryians Coding School. 💪 Harsh Vandana Sharma Sheryians Coding School #JavaScript #WebDevelopment #Frontend #SheryiansCodingSchool #CodingJourney #SmartWork #HardWork #LearningByDoing #Functions #Closures #Arrays #Objects #GrowthMindset

🚀 Day 38 — Cohort 2.0 of Web development with Sheryians Coding School Today I explored some core JavaScript fundamentals that every developer should understand deeply. 🧠 Topics I covered: 🔹 Pure vs Impure Functions — Learned how pure functions always produce the same output for the same input and have no side effects, while impure functions can behave differently depending on external factors. 🔹 Closures — Understood how a function can access variables from its parent scope even after the parent has finished executing. Closures are the backbone of many advanced JS concepts. 🔹 Arrays & Their Methods — Practiced using array methods to add, remove, and manipulate data efficiently. Also explored how the spread operator helps clone and merge arrays easily. 🔹 Objects & Nested Objects — Discovered how objects organize data as key-value pairs and how nesting allows us to represent structured, real-world data more effectively. 💡 Each concept makes me more confident in writing cleaner, smarter, and more logical JavaScript code. Excited to keep building my foundation stronger every day! #Day38 #JavaScript #WebDevelopment #DSA #SheryiansCodingSchool #LearningJourney #FrontendDeveloper #GenAI #100DaysOfCode Harsh Vandana Sharma Sheryians Coding School Community

🚀 Day 35 - Deep Dive into Loops | JavaScript Today’s session took our JavaScript journey to the next level! We explored advanced looping concepts through Level-2 problem-solving exercises, combining for, while, and user interactions with prompt(). 💡 Key Learnings: 🔹 Strengthened logical thinking through real-world problems. 🔹 Broke down complex tasks into smaller, manageable steps. 🔹 Wrote dynamic code that interacts with user input. 🔹 Used loops and conditionals to generate specific outputs and patterns. 🧠 Harsh Bhaiya guided us to approach each challenge strategically first understanding the problem, visualizing loop flow, and then crafting efficient solutions. His advice reminded us that true learning happens when we struggle, reason, and solve independently. Each question solved today added to my confidence and made me appreciate how loops truly power logic in programming. Feeling proud, prepared, and excited to take on even tougher challenges ahead! 💪 📚 Student at: Sheryians Coding School #JavaScript #WebDevelopment #CodingJourney #LearningEveryday #SheryiansCodingSchool #ProblemSolving

Day 32 — Loops & Conditional Logic in JavaScript | 2.0 Job-Ready AI-Powered Cohort Sheryians Coding School 🚀 Today was all about building strong control-flow logic in JavaScript: 🟡 Truthy & Falsy Values Falsy → 0, "", null, NaN, undefined, false, document.all Everything else is Truthy ✅ 🧠 Conditional Statements if, else, if-else, else-if switch Ternary Operator for compact logic 🔁 Loops for loop basics & patterns ⛔ Loop Control Statements break — exit loop continue — skip to next iteration Understanding these deeply helps write cleaner, efficient control flow and decision-making logic in JS 💡 #JavaScript #WebDevelopment #Frontend #ControlFlow #SheryiansCodingSchool #DeveloperJourney

🚀 #Day27 #Cohort2.0| Sheryians Coding School| #Javascript |#part3 Today’s session was about JavaScript concepts that form the real foundation of programming logic. ✅Here’s a quick summary of what I learned today 👇 1️⃣ Variables – var, let, and const 🔸 var is function-scoped (the old way), 🔸 while let and const are block-scoped 🔸 value is fixed in const (no change once declare) 🔸In let value can be re-declare and change 2️⃣ Console Methods Tried out several console functions: 🔸console.log() for normal output 🔸console.info() for informational messages 🔸console.warn() for warnings ⚠️ 🔸console.error() for errors ❌ 🔸console.table() for visualizing data neatly in tables 🔸console.dir() for seeing the structure of objects clearly 3️⃣ Prompt & Alert 🔸alert() ->for showing messages 🔸prompt() -> for taking quick input from the user. 4️⃣ Strings 🔸 Denoted by " ", ' ' 🔸" no. + any character/special symbol " -> " " string ✅slice() ->to extract a part of the string ✅split() ->to break text into arrays ✅replace() & replaceAll-> to change specific parts ✅includes() -> to check if a word exists inside a string 5️⃣ Template Strings (Template Literals) Used backticks ` ` instead of quotes to create cleaner and dynamic strings. The best part? You can directly use variables inside like this: `Hello ${name}, welcome back!` ✨ Every session in Cohort 2.0 is helping me sharpen my basics and think like a real developer - step by step. Learning how these small concepts connect to build bigger projects is truly satisfying. Thank you Harsh Vandana Sharma bhaiya for the wonderful lecture. #JavaScript #WebDevelopment #LearningJourney #Cohort2_0 #FrontendDevelopment

✨ Day 26 – Cohort 2.0 at Sheryians Coding School 🚀 Today, we officially began our JavaScript coding journey with Harsh Vandana Sharma, and it was the perfect start to understanding how the web truly comes alive through logic and interactivity. 💻 Key learnings: ▪️ Understood what JavaScript is and why it’s a core part of modern web development. ▪️ Learned how to connect JS with HTML using the <script> tag. ▪️ Explored how JavaScript runs inside the browser environment. ▪️ Practiced variables (var, let, const) and how they differ in scope and reassignments. ▪️ Worked with console, prompt, and alert to interact with users. ▪️ Discovered strings and tried out methods like slice(), split(), replace(), and includes(). ▪️ Used template literals for cleaner and more readable code. #Day26 #SheryiansCodingSchool #Cohort2 #JavaScript #FrontendDevelopment #WebDevelopment #CodingJourney #HarshVandanaSharma #Programming #LearningJourney #TechEducation #Consistency #DeveloperMindset

I used to think functions were just a simple way to wrap code. I was wrong—they're the key to writing truly clean, reusable code. Following up on my last post about my practice landing page (two weeks ago!), I spent the past few weeks diving deep into JavaScript functions. My biggest moment? Function Scope! It’s basically a protective bubble. Any variables defined inside the function stay locked inside. This focus on isolation is huge for building reliable code and is a core part of the DRY (Don't Repeat Yourself) principle. Learning functions feels like unlocking the real power of JavaScript. Excited to dive into objects next! What was the first JavaScript concept that truly made you go, "Aha!"? Sheryians Coding School #JavaScript #WebDevelopment #CodingJourney #Functions #FrontendDev

DAY 25 — JavaScript Deep Dive Begins Sheryians Coding School | Sheryians AI School Before today’s live class, I completed the task given by Bhaiya, which was to watch a 1-hour video on “JS Learn Everything” on YouTube. From that video, I learned about the history and introduction of JavaScript, keywords, variables (var, let, const), and their scopes (global, block, function). I also understood key concepts like reassignment, re-declaration, temporal dead zone, and hoisting — which form the base of how JavaScript actually works behind the scenes. ⚙️ In today’s live session, we continued our journey with: 📘 Introduction to JS 💡 Why it’s important 🤔 What can it do for you 🖥️ Using script tag & running JS in browser 🧠 Variables and alerts (var, let, const, prompt, console) It was a great start to understanding how JavaScript brings life and interactivity to web pages! 🌐 Mentor: Harsh Vandana Sharma #Day25 #Cohort2_0 #JavaScript #FrontendDevelopment #WebDevelopment #SheryiansCodingSchool #LearningJourney #CodingLife
