Day 36 — Loops & Conditions | 2.0 Job-Ready AI-Powered Cohort Sheryians Coding School🚀 Leveled up with Level 2 practice and deeper control flow concepts: ✅ Q17 & Q18,Q19 solved 🔁 do...while loops — run at least once 🧠 Recursion in JS — thinking in functions (factorial/sum patterns) 🧭 Loop control deep dive — break, continue, and clean exit patterns Tiny drills I wrote today: // do...while let i = 1; do { console.log(i++); } while (i <= 5); // recursion (factorial) const fact = n => (n <= 1 ? 1 : n * fact(n - 1)); // loop control for (let x = 1; x <= 10; x++) { if (x % 2 === 0) continue; // skip evens if (x > 7) break; // stop early console.log(x); } → Overview Function in JS Sharpening reasoning with both iterative and recursive mindsets 🔥 #JavaScript #WebDevelopment #Frontend #ProblemSolving #SheryiansCodingSchool #100DaysOfCode

🚀 Day 30 of My COHORT 2.0 Development Journey Sheryians Coding School Topic: Operators in JS Today’s class focused on one of the most important foundations of JavaScript: Operators. Operators help us perform calculations, assign values, compare data, and write logical conditions - basically the backbone of any program. Here’s what we covered: 🔢 1️⃣ Arithmetic Operators Used for basic mathematical operations: + , - , * , / , % , ** These help us calculate values and perform number-based logic. 📝 2️⃣ Assignment Operators Used to assign or update variable values: = , += , -= , *= , /= , %= They make updating values shorter and cleaner. ⚖️ 3️⃣ Comparison Operators Used to compare two values: == , === , != , !== , > , < , >= , <= These return true/false and are essential for conditions, loops, and decision-making. 🔐 4️⃣ Logical Operators Used to combine multiple conditions: && (AND) || (OR) ! (NOT) These help in creating complex logical checks in real-world applications. 🧠 Key Takeaway: Operators may look simple, but they form the base of every function, condition, calculation, and logic flow in JavaScript. Today’s class helped me understand how they work behind the scenes and how to use them effectively while building real projects. #JavaScript #Cohort2 #WebDevelopment #FrontendDevelopment #CodingJourney #OperatorsInJS #LearnByDoing #SheriyansCodingSchool

🚀 [Day 15/30] Coding Challenge Journey with @Educative.io 💻 💡 Problem: Similar String Groups Today’s problem was all about identifying relationships between strings and grouping them based on their “similarity.” Two strings are considered similar if they differ in exactly two character positions — meaning you can swap those characters to transform one into the other. My intuition started with this core idea: 👉 If two strings differ by exactly two positions, they belong to the same group. To solve this, I approached the problem like a graph traversal challenge: 1️⃣ Consider each string as a node in a graph. 2️⃣ Create an edge between two nodes if the strings differ by exactly two characters. 3️⃣ Use DFS to explore all connected strings that form a similarity group. 4️⃣ Maintain a visited array to ensure each string is processed once. So for each unvisited string, I triggered a DFS call. That DFS marked all strings connected to it (all strings that were similar by 2-character difference). This naturally formed groups of similar strings — each connected component counted as one group. This problem beautifully reinforced how string similarity + graph connectivity can come together to form a clean and efficient solution 🧠✨ 🔍 Key Learnings: Many string problems hide an underlying graph structure — discovering it is half the solution. DFS is extremely powerful for grouping, clustering, and connectivity problems. A simple rule (differ by 2 characters) can create surprisingly complex group relationships. ✨ Small win — once I mapped the problem to graph traversal instead of brute-force comparisons, everything became much more intuitive! #30DaysOfCode #Day15 #CodingChallenge #Educative #DSA #GraphTheory #DFS #JavaScript #ProblemSolving #StringAlgorithms #LearningJourney #KeepCoding

💡 DAY 28 & 29 — Deep Dive into JavaScript Operators Sheryians Coding School | Sheryians AI School These two days were super productive and helped me strengthen my JavaScript fundamentals! 💻 On Day 28, we had a practice session where we solved the assignments given earlier. It was all about applying what we’ve learned so far — writing, testing, and improving our JS code step by step. 🧠 Then on Day 29, we started an in-depth session on JavaScript Operators. Our mentor explained every operator type in detail and how they actually work in real scenarios. ⚙️ Topics Covered: 🔹 Arithmetic Operators — for performing mathematical operations 🔹 Assignment Operators — for assigning and updating values 🔹 Comparison Operators — to compare two values 🔹 Logical Operators — for combining multiple conditions 🔹 Ternary Operator — shorthand for if-else conditions 🔹 Type Checking Operator — to identify data types 🔹 String Operators — for concatenation and manipulation 🔹 Spread & Rest Operators — for copying and grouping data 🔹 Nullish Coalescing Operator (??) — handling null or undefined safely 🔹 Optional Chaining Operator (?.) — to access nested properties without errors We also discussed Variable Hoisting, which helped me understand how JS moves variable declarations to the top during execution. These two sessions made a lot of tricky concepts easy and clear — step by step I’m feeling more confident with JavaScript! 🚀 Instructor: Harsh Vandana Sharma #Day28 #Day29 #Cohort2_0 #JavaScript #FrontendDevelopment #WebDevelopment #LearningJourney #CodingLife #JSOperators #PracticeSession #SheryiansCodingSchool

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
