Learned loops, recursion, and functions in JavaScript with Sheryians Coding School

Day 6 of Learning JavaScript  from Sheryians Coding School Today, I have learned about Conditionals and Loops.  Conditionals:   if: Inside this block, a condition is tested that returns true or false.   Falsy values: 0, "", NaN, null, false, undefined, document.all   Truthy values: Everything other than falsy values.   else: Executes when the if condition is false.   else if: Executes when the if condition fails, but another specific condition needs to be checked.  Ternary Operator:   condition? true: false  Switch:   Used to check multiple conditions.   You can create multiple cases inside a switch.   Each case runs when the passed condition matches the case value.   Always write a break after each case to stop further execution.  Loops:   There are two main types of use cases:   1. Straightforward loop: The value and printed result do not change.   2. Dynamic loop: Both the value and printed output can change.  For Loop:   for (start; end; change) { }   Used to repeat a block of code multiple times.   You can start the loop from any value, for example, 100, 1999, or 6778 in a straightforward loop.  #JavaScript #WebDevelopment #CodingJourney #LearningWithSheryians #ProgrammingBasics

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 33 — Loops & Conditions Practice | 2.0 Job-Ready AI-Powered Cohor Sheryians Coding School🚀 Today was all about hands-on coding with JavaScript loops & conditionals. Practiced real logic-building exercises like: ✅ Print numbers 1 to 10 ✅ Print even numbers using loops + condition ✅ Print numbers 10 to 1 (reverse loop) ✅ Print "YES" 5 times using a loop ✅ Ask a number → check positive or negative ✅ Ask user's age → check voting eligibility ✅ Multiplication table of 5 using loop ✅ Understand & handle edge cases with if-else The more I practice these logic patterns, the more comfortable I get with problem-solving in JavaScript 💪 #JavaScript #WebDevelopment #Frontend #CodingPractice #SheryiansCodingSchool #100DaysOfCode #DeveloperJourney

🚀 Day 4 | 30-Day Coding Challenge – Educative.io Today’s problem: Find the single non-duplicate element in a sorted array. At first, I explored the simple O(n) approaches — 🔹 Using a Set to track duplicates (O(n) time + O(n) space) 🔹 Summing unique vs. total values and finding the difference (O(n) time) 🔹 Linear scan comparing curr and next (O(n) time, O(1) space) All worked… but the goal was O(log n) time and O(1) space. Then it clicked 💡 — since the array is sorted, every pair of equal numbers appears side-by-side. Before the unique element, pairs start at even indices; after it, they start at odd indices. Using this pattern with binary search, I halved the search space each step: if nums[mid] == nums[mid+1] → move right else move left. Every challenge so far is sharpening how I reason about patterns and constraints rather than just syntax. #Day4 #30DaysOfCode #Educative #JavaScript #BinarySearch #ProblemSolving #DSA #LearningInPublic

🚀 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 37 — Functions in JavaScript (All Topics Covered) Today at Sheryians Coding School Cohort 2.0, we completed one of the most important concepts in JavaScript — Functions. 💻 Here’s what I learned and practiced: ✅ Function declaration and expression ✅ Parameters and return values ✅ Function scope and variable accessibility ✅ Arrow functions and their syntax ✅ Real use cases of functions in programs Understanding how functions work felt like learning how to organize logic smartly. They make code cleaner, reusable, and easier to debug — a true backbone of JavaScript programming. Takeaway: Functions aren’t just blocks of code — they’re the heart of every program. Mastering them makes everything ahead much easier! 🚀 #Day37 #ShreyiansCodingSchool #Cohort2 #JavaScript #Functions #CodingJourney #FrontendDevelopment #LearnByDoing #Consistency

Today, I learned that in JavaScript, NaN is a number that isn't equal to itself, typeof null is an object (don't ask), and can someone please explain to me how 0.1 + 0.2 decided to become 0.30000000000000004? 🤔 Also, addition concatenates strings, while subtraction actually calculates! 🤦♂️ Everything from a prompt() is a string, so be careful with those data types! Successfully conquered yesterday's tasks in Sheryians Coding School Cohort 2.0. The code runs, but the confusion is real. 😂 #JavaScript #JSDev #CodingLife #SheryiansCohort2 #WebDevelopment

🧑💻Day 39 — Practicing Basic Level 1 Questions on Arrays and Objects (JavaScript) Today at Sheryians Coding School Cohort 2.0, we practiced basic level 1 questions based on arrays and objects in JavaScript. 💻 Here’s what we worked on during the live session with sir: ✅ Accessing values from arrays and objects ✅ Updating and modifying elements ✅ Understanding how data is stored and retrieved ✅ Writing simple programs using arrays and objects It was a light but important practice session that helped me understand the core logic behind how data works in JavaScript. Takeaway: Even the simplest questions help build a strong foundation. Mastering the basics is the real key to becoming good at coding. 🚀 #Day39 #ShreyiansCodingSchool #Cohort2 #JavaScript #Arrays #Objects #CodingJourney #FrontendDevelopment #PracticeSession #LearningByDoing

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
