Learned JavaScript fundamentals at Sheryians Coding School

🚀 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 35 of #100DaysOfCode – Functions, Recursion & Do-While Loop in JavaScript Today’s learning focused on some of the most important programming fundamentals in JavaScript: Key Learnings: Do-While Loop → Understanding how it executes the block at least once before checking the condition Functions in JavaScript → Structure, reusability, and clean code Arguments vs Parameters → How data is passed and handled Rest Parameters → Efficient way to work with variable number of inputs Recursion → Calling functions within themselves to solve repeating subproblems Hoisting → Variable Hoisting — behavior differences between var, let, and const Function Hoisting — how JavaScript moves function declarations to the top during execution Takeaway: Functions and recursion unlock powerful logic possibilities, and understanding hoisting helps avoid unexpected bugs. These concepts form the backbone of writing optimized and predictable JavaScript code. A big thanks to Harsh Vandana Sharma from Sheryians Coding School and Sheryians Coding School Community for making function mechanics and hoisting concepts easy to understand with practical examples. #100DaysOfCode #JavaScript #Functions #Recursion #WebDevelopment #CodingJourney #Frontend

🚀 Day 29 of My COHORT 2.0 Development Journey, Sheryians Coding School Topic: Completing JS Assignment + Primitive vs Reference Types Today’s class was focused on finishing the JavaScript assignment from Day 28, which covered console methods, alerts, prompts, string operations, variables, and more. Working through each task helped strengthen my JS fundamentals with real examples. Then we moved to an essential concept in JavaScript: 🔍 Primitive vs Reference Types: 📚 Primitive Types ➡️ Stored directly in memory as values ➡️ Immutable ➡️ Copied by value Includes: string, number, boolean, undefined, null, bigint, symbol Example: let a = 10; let b = a; // b is a copy 📚 Reference Types ➡️ Stored as memory references ➡️Mutable ➡️Copied by reference Includes: object, array, function Example: let obj1 = { name: "Harsh" }; let obj2 = obj1; // same memory obj2.name = "Sheryians"; 🧠 Key Takeaway: Understanding how JavaScript stores and copies data is mandatory for avoiding bugs, managing memory, and writing predictable logic. Today really clarified value vs reference behavior in depth. #JavaScript #Cohort2 #FrontendDevelopment #WebDevelopment #CodingJourney #DataTypes #SheriyansCodingSchool #SarthakSharma

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 43 | Cohort 2.0 Journey Session was fully packed with pure JavaScript concepts through practical examples by Harsh Vandana Sharma from Sheryians Coding School: ✔️ Higher Order Functions ✔️ Pure vs Impure functions ✔️ Function destructuring ✔️ Normal vs Arrow functions (this difference!) ✔️ map(), filter(), reduce() ✔️ some() & every() ✔️ Object.freeze() & Object.seal() ✔️ Optional chaining ✔️ Nested objects ✔️ Real logic-building questions From HOFs to object behaviour to array transformations got really connected with lot of core concepts together. #Day42 #Day43 #JavaScript #SheryiansCodingSchool #LearningJourney #ProblemSolving #HOF #ArrowFunctions #FrontendDevelopment #Cohort2

🚀 Day 32 of my Web Development Journey, Cohort 2.0 (Sheryians Coding School) Today’s class focused on understanding Conditionals and Loops in JavaScript, two of the most important building blocks for logic and flow control in programming. Conditionals in JavaScript Conditionals help a program make decisions based on certain conditions. We explored how to use if, else if, else, the ternary operator, and switch case statements to control what part of the code runs depending on the situation. We also discussed Truthy and Falsy values: • Falsy values include false, 0, an empty string, null, undefined, NaN, and document.all. • Everything else in JavaScript is considered Truthy. The ternary operator is a shorter way to write simple if-else conditions, while the switch case is used when multiple possible outcomes need to be checked in an organized manner. Loops in JavaScript Loops allow us to repeat a block of code multiple times without writing it again and again. We focused on the for loop, which is commonly used when the number of iterations is known in advance. By using loops, we can perform repetitive tasks efficiently, reducing code redundancy and improving performance. Today’s session really strengthened my understanding of how logic flows inside a program, making it easier to write cleaner, smarter, and more efficient JavaScript code 💪 Stay tuned 🔥 ❤️ #WebDevelopment #Cohort2 #SheriansCodingSchool #LearningInPublic #HTML #CSS #FrontendDevelopment #BackendDevelopment #FullStackDevelopment #LearningJourney

🚀 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
