Mastering JavaScript Fundamentals with Hitesh Choudhary

Day 15 of learning to code. Today I explored arrow functions in JavaScript, and honestly, they make things feel much simpler. Earlier, I used to write functions like this: function add(a, b) { return a + b; } Now with arrow functions, it becomes: const add = (a, b) => a + b; Same output, but the code feels shorter and cleaner. I also noticed that arrow functions are really useful when dealing with small tasks, especially while working with arrays. For example: const numbers = [1, 2, 3]; numbers.forEach(num => console.log(num)); It just feels more natural to read and write. One small but important realization today: Writing better code doesn’t mean writing more code. It means writing it in a simpler, clearer, and more efficient way.

JavaScript's array methods map, filter, and reduce are game changers for developers aiming to write clean, efficient, and maintainable code. These methods allow us to transform, select, and aggregate data in arrays with simple, expressive functions. Whether you're doubling numbers, filtering specific data points, or calculating sums, mastering these built-in functions can dramatically improve your code readability and performance. In my latest article, I share practical examples and best practices to help you unlock the full potential of these methods. How do you use map, filter, or reduce in your projects? Let's discuss strategies to leverage these tools for better coding outcomes. #javascript #webdevelopment #programming #codingtips #softwareengineering Check out the actual blog here : https://lnkd.in/gcGRNu2v

Programming is more than just writing lines of code; it's about making decisions. 🚦 In my latest blog post, I dive deep into Control Flow in JavaScript. I break down how if, else, and switch statements act as the "GPS" for your code, directing logic based on real-world scenarios. What you’ll learn: ✅ The logic behind if-else vs. switch ✅ Why the break keyword is a lifesaver in switch cases ✅ A side-by-side comparison for cleaner code Perfect for beginners or anyone looking to sharpen their JS fundamentals! 🚀 Read more here: https://lnkd.in/dwuvC9jq #JavaScript #WebDevelopment #Programming #BeginnerCode #LearningToCode #Hashnode

Day 64 of My 9-Month Coding Challenge 🎯 💻 Day 64 Complete | Working with Promises in JavaScript ⚡ Consistency is the real key to learning programming. Every day I try to understand not just how code works, but why it works that way. Small progress every day leads to big results over time. 🚀 Today’s Focus: ✔ Understanding Promises in JavaScript ✔ Learning how asynchronous operations work ✔ Handling success and failure using .then() and .catch() ✔ Understanding how Promises help manage asynchronous tasks 📚 What I’m Learning: ✅ What a Promise is and why it is used in JavaScript ✅ The three states of a Promise: pending, fulfilled, and rejected ✅ How .then() handles successful results ✅ How .catch() handles errors in asynchronous operations Promises are a fundamental concept in modern JavaScript. They help manage asynchronous tasks like API calls, file operations, and network requests in a more structured way. Understanding Promises is essential before mastering async/await and building scalable applications. Learning and practicing through resources and guidance from Coding Ninjas. No shortcuts, just consistency. 🎯 Still learning. Still improving. Still consistent. 💯 #Day64 #9MonthChallenge #JavaScript #Promises #AsyncJavaScript #MERNStack #WebDevelopment #LearningInPublic

Life lessons from JavaScript arrays 💻 Too many dreams? Use Array of Objects – organize them with structure. Looking for the exact opportunity? Use find() – focus on what truly matters. Facing too many problems? Use reduce() – break them down and solve step by step. Want to improve daily? Use map() – transform yourself into a better version. Need to remove negativity? Use filter() – keep only what helps you grow. Coding teaches more than programming… It teaches how to think, simplify, and build solutions in life. Happy reading and happy coding. 🚀 #JavaScript #CodingLife #DeveloperMindset #ProblemSolving #LearningJourney

Day 75 of #100DaysOfCode – Working with Local Storage in JavaScript Today I explored Local Storage and how browsers can store data locally to persist information even after refreshing the page. What I Learned & Implemented: Storing data using localStorage.setItem() Retrieving data using localStorage.getItem() Removing specific items with removeItem() Clearing all stored data using clear() Storing objects in Local Storage using JSON.stringify() Retrieving and converting them back using JSON.parse() Key Takeaway: Local Storage is useful for storing small amounts of persistent data like user preferences, tokens, or session-like information on the client side. Understanding how to convert objects into strings and back makes it much more powerful for real applications. Grateful to Sarthak Sharma from Sheryians Coding School and Sheryians Coding School Community for setting the foundation right before jumping into React Every small concept like this adds another tool to the frontend toolbox. #100DaysOfCode #JavaScript #WebDevelopment #FrontendDevelopment #LocalStorage #CodingJourney #BuildInPublic

🚀 Get ready to supercharge your coding game! Functional programming is the secret sauce 💡 that can elevate your JavaScript skills to new heights! Ever heard people rave about it but not sure why? It's not just a fad—it's a powerhouse tool. Imagine writing code that’s clean, bug-resistant, and easy to test. That's the magic of functional programming. Think about functions like you do pizza slices: everyone takes their piece without taking the whole pie. Yum! Functional programming's core concepts—pure functions, immutability, and higher-order functions—can make your code predictable and efficient. It's not just for the algorithm wizards; even practical web apps benefit hugely! Would you give this a spin in your next project? 🤔 Let’s get the conversation started!

Strings look simple… until you actually start solving problems with them Today I spent time doing DSA on Strings, and honestly, it was one of those “simple but tricky” days. While solving problems, I explored a lot of string methods like: • slice() • substring() • split() • indexOf() • concat() And that’s when I realized — knowing methods is one thing, but knowing when to use which one is the real game. Then came my React session at Sheryians Coding School (Kodex Batch) with Devendra Dhote bhaiya And things got even more interesting. We explored form handling in a more optimized way using useRef() — which felt very different from the usual useState approach. Also got introduced to form handling using npm packages, which made me realize how real-world apps handle complex forms much more efficiently. Today’s takeaway: Sometimes the basics (like strings & forms) teach you the deepest lessons. What do you find more tricky — Strings in DSA or Forms in React? #JavaScript #DSA #ReactJS #WebDevelopment #LearningInPublic #SheryiansCodingSchool #FrontendDevelopment

🚀 State vs Props in React — Understanding the Core Difference When learning React, one of the most common questions developers have is the difference between State and Props. Both help manage data in components, but they serve different purposes. 🔹 State State represents data managed inside a component. • Controlled by the component itself • Can change over time • Updated using useState or setState • Triggers UI re-render when updated • Used for dynamic behavior like counters, form inputs, or login status 🔹 Props Props are data passed from a parent component to a child component. • Passed from parent → child • Read-only (cannot be modified by the child) • Used to make components reusable • Helps configure and customize components 🧠 Simple Way to Remember State → Managed inside the component Props → Passed from the parent component Both work together to make React applications dynamic, reusable, and scalable. Still exploring the fundamentals and building in public. 🚀 — Anuj Pathak #reactjs #javascript #webdevelopment #frontenddevelopment #softwareengineering #developersoflinkedin #coding #programming #techlearning #learninginpublic #softwaredeveloper #buildinpublic

One small mistake in my code today cost me almost an hour. The bug? A missing await. Everything looked correct. The API was fine. The logic was fine. But the response kept coming back wrong. After checking the code again and again, I finally spotted it. I forgot to add await to an async request. One word. Four characters. That tiny mistake completely changed how the program behaved. Moments like this remind me of something important about programming: Coding is not just about writing logic. It’s about paying attention to the smallest details. The difference between a working application and a broken one can sometimes be just one word. Still learning. Still debugging. Still improving. 💻 #BackendDevelopment #NodeJS #CodingLife #SoftwareDeveloper #Debugging #BuildInPublic #DevelopersOfLinkedIn
