How to Master JavaScript with Sheryians Coding School

🚀 My Takeaways After Learning Asynchronous JavaScript After spending some time diving deep into asynchronous JavaScript, here’s what I’ve come to realize 👇 💡 In modern JavaScript development, understanding async behavior isn’t optional anymore — it’s essential. 🧠 JavaScript runs on a single thread, and without async operations, our apps would freeze every time we wait for an API call or heavy data processing. ⚙️ That’s where callbacks, promises, and async/await come in — they keep our code responsive, efficient, and user-friendly. #JavaScript #Programming #WebDevelopment #FrontendDevelopment #CodingJourney #LearnToCode #SoftwareEngineering #DeveloperCommunity #100DaysOfCode A quick example 👇

Day 36 of #100DaysOfCode – Understanding Functions Deeply in JavaScript Today’s session was all about exploring how functions truly behave in JavaScript  from their structure and parameters to their scope and execution flow. Key Learnings: Function Parameters: Required, destructured, rest, and default parameters. Function Arguments: Positional, default, and spread arguments, and how they’re passed into functions. Function Types: Classic functions, nested functions, and understanding the scope chain. IIFE (Immediately Invoked Function Expression): How and why it’s used for self-executing logic. Explored advanced function concepts: Arrow functions, anonymous functions, and callback functions. High-order functions for passing logic dynamically. Pure vs Impure functions  understanding side effects and predictable behavior. Scoping: Deep dive into global scope and function scope to understand variable visibility and lifetime. Takeaway: Functions are the heart of JavaScript. Understanding their types, parameters, and scopes is crucial for writing modular, reusable, and efficient code. Grateful to Harsh Vandana Sharma from Sheryians Coding School and Sheryians Coding School Community for explaining complex function behaviors with clear examples and hands on exercises. #100DaysOfCode #JavaScript #Functions #WebDevelopment #Frontend #CodingJourney #LogicBuilding

Just wrapped up a deep dive into JavaScript Objects! 💡 Key takeaways: - They're collections of key-value pairs (properties and methods). - Mastered accessing them with dot and bracket notation. - Crucially, they are mutable (even with const) and passed by reference. A fundamental building block of JS! On to the next concept. #JavaScript #WebDevelopment #Coding #Codecademy

🎯 Day 1 — Deep Dive into JavaScript Fundamentals Today I started my journey to strengthen the core of JavaScript, and it’s amazing how much depth lies behind the basics! 🚀 Here’s what I learned today: 🧩 Primitive vs Reference Types 🧠 typeof Operator Behavior ⚖️ Difference Between null and undefined 🪄 var vs let vs const and Variable Hoisting ⛔ Temporal Dead Zone (TDZ) 📦 Block Scope vs Function Scope 🔄 Implicit vs Explicit Type Conversion ✅ Truthy and Falsy Values 🔍 Comparison Operators & Type Coercion 🔧 Object to Primitive Conversion (valueOf, toString) 👇 Understanding this in Different Contexts: Global Context Object Methods Constructor Functions Arrow Functions Event Handlers Explicit & Implicit Bindings new Keyword Every topic connected like a puzzle — learning how JavaScript really works behind the scenes makes it even more exciting to code. 💻 #JavaScript #WebDevelopment #Day1 #LearningJourney #Frontend #Coding

Day 28 – JavaScript Basics Today’s session was all about getting a clear introduction to JavaScript — understanding what it is, why it’s important, and how it works inside the browser. ✨ What I learned today: What is JavaScript & why it matters How to link JS using the <script> tag Running JS in the browser Difference between var, let, const Using console, prompt, and alert What are strings and how to use methods like slice(), split(), replace(), and includes() This session really helped strengthen my JS foundation.

✨ Mastering JavaScript means understanding not just 𝘸𝘩𝘢𝘵 works - but 𝘸𝘩𝘺 it works. In our new blog post, “𝙁𝙧𝙤𝙢 𝙄𝙣𝙩𝙪𝙞𝙩𝙞𝙤𝙣 𝙩𝙤 𝙋𝙧𝙤𝙛𝙞𝙘𝙞𝙚𝙣𝙘𝙮: 𝙁𝙪𝙣𝙘𝙩𝙞𝙤𝙣 𝙏𝙧𝙖𝙣𝙨𝙛𝙤𝙧𝙢𝙖𝙩𝙞𝙤𝙣𝙨 𝙞𝙣 𝙅𝙖𝙫𝙖𝙎𝙘𝙧𝙞𝙥𝙩”, Anju Karanji unpacks that mindset beautifully. 💜🧠 If 𝗣𝗮𝗿𝘁 𝟮 was about chaining and composing functions, 𝗣𝗮𝗿𝘁 𝟯 dives into how functions themselves can evolve - transforming behavior, optimizing performance, and reshaping how we think about logic. ⚙️💭 Anju takes you on a journey from simple wrappers → to once-only execution patterns → to building your own memoization utility that makes code both elegant and efficient. 🧩✨ 🔍 𝗪𝗵𝗮𝘁 𝘆𝗼𝘂’𝗹𝗹 𝗹𝗲𝗮𝗿𝗻: 🎯 How higher-order functions reshape behavior 🧱 Building a once() wrapper from scratch ⚡ Implementing memoization for smarter performance 💡 When (and why) to use these transformations in real-world frontend code If you’re diving deeper into React, TypeScript, or just love exploring JavaScript patterns that scale, this post is packed with hands-on insights and aha moments. 📰 Read the full article: https://lnkd.in/dqbuHGq3 💌 Subscribe for more updates: https://lnkd.in/gDA5t-yP #FrontendQueens #WomenInTech #JavaScript #FunctionalProgramming #React #WebDevelopment #TechBlog

Day 29 of #100DaysOfCode – Deep Dive into JavaScript Operators & Hoisting Today’s session focused on understanding the wide range of JavaScript operators and how they function in real-world code. Key Learnings: Explored different types of operators: arithmetic, comparison, logical, assignment, ternary, type-checking, and string operators. Understood advanced concepts like spread/rest operators, nullish coalescing, and optional chaining. Learned about variable hoisting  how JavaScript handles variable declarations internally, and the differences in behavior between var, let, and const. Takeaway: A clear understanding of operator precedence and hoisting helps write cleaner, bug-free, and optimized JavaScript code. Grateful to Harsh Vandana Sharma from Sheryians Coding School for making today’s concepts practical and easy to grasp. #100DaysOfCode #JavaScript #WebDevelopment #CodingJourney #Frontend

🎯 Day 33 - Learning Loops in JavaScript Today's session was all about understanding how loops make our code more efficient and powerful by reducing repetition and improving logic flow. 💡 Key Learnings: for loop - runs code for a fixed number of times. while loop - continues as long as the condition is true. do...while loop - executes at least once before checking the condition. for...of loop - iterates over arrays and strings. for...in loop - iterates through object properties. Each loop serves a unique purpose, and together they make JavaScript more dynamic and versatile. Excited to keep exploring and sharpening my logical thinking every single day! 🚀 #Day33 #JavaScript #WebDevelopment #CodingJourney #FrontendDevelopment #SheryiansCodingSchool #LearningNeverStops

As I continue learning JavaScript, I’m diving deeper into its core concepts. Today, I explored Hoisting, and it helped me understand how JavaScript handles code behind the scenes. What I learned about Hoisting: ~JavaScript moves variable and function declarations to the top of their scope before executing the code. This means: ~Functions can be called before they are declared ~Variables are initialized with undefined during the compilation phase ~Understanding execution context is crucial for clean and predictable code Why this concept is important? Hoisting may seem simple, but it forms the foundation of how JavaScript interprets code. It improves my understanding of: ~Execution phases ~Scope behavior ~Memory allocation ~Writing more structured and bug-free code My learning journey I’m currently focusing on strengthening my fundamentals concepts like: ~Hoisting ~Scope ~Closures ~Event loop ~DOM manipulation These basics are helping me build a strong foundation before moving toward frameworks and advanced topics. Every concept I learn brings me closer to writing cleaner, more efficient JavaScript. #JavaScript #LearningJourney #WebDevelopment #ProgrammingBasics #FrontendDeveloper

🚀 Did you know? In JavaScript, setTimeout(..., 0) doesn’t actually run immediately. It runs after all Promises and await calls — even if the delay is 0ms 🧠 Why? Because JS runs all microtasks (like Promises and await) before moving on to macrotasks (like setTimeout, setInterval, etc.). 💡 Takeaway: Understanding the event loop helps you fix async bugs and write smoother, predictable code. #JavaScript #Coding #WebDevelopment #EventLoop #AsyncProgramming #CodeTips #Developers #Learning #letsLearnWithPrateek #Day7 Here’s proof 👇
