If anyone is interested in developing their skills in JavaScript, a quick thought based on my experience that might be helpful. 💬 Here are some tips for developing this skill: If anyone is interested in developing their skills in JavaScript, here are a few simple tips that helped me and might help you too: 💡 1. Understand the basics first Learn variables, loops, functions, arrays, and objects. These are the foundation of everything in JavaScript. 💡 2. Practice small projects Start with easy things like a calculator, to-do list, stopwatch, or a color changer. Small projects build confidence fast. 💡 3. Use the browser console Right-click → Inspect → Console. Practice writing small pieces of code and see results instantly. 💡 4. Learn DOM manipulation This helps you make your webpages interactive. (Example: changing text, colors, showing/hiding elements.) 💡 5. Break problems into steps Instead of thinking “how do I build it,” think ➡ “What should happen first?” ➡ “What do I want the code to do next?” 💡 6. Ask questions and experiment Don’t be afraid of errors. Every error is teaching you something. 💡 7. Use online resources YouTube (CodeWithHarry), MDN Docs, W3Schools — all great for beginners. If you're starting out, keep it simple and focus on consistency. A little practice every day makes a huge difference.

🚀 Understanding map(), filter() & reduce() — finally makes sense 😅 When I first started learning JavaScript, these three functions — map(), filter(), and reduce() — honestly felt like magic spells 🪄 that everyone said were “super important for React.” But for me? Total confusion at first. 😵 Then last night, I found this amazing video that explained everything step-by-step 👇 🎥 https://lnkd.in/gnMXj99Z After watching it, I started writing small code snippets for each function — and that’s when things finally clicked! 💡 Here’s how I understand them now: ✨ map() → transforms each element in an array (like converting all prices into discounts) ✨ filter() → picks only the elements you need (like filtering completed todos) ✨ reduce() → combines everything into one value (like summing up scores) Now I get why everyone calls them must-know functions — once you understand the logic, your JS code becomes cleaner, shorter, and way smarter 💻 If you’re a frontend dev (or learning React), seriously — take an hour, watch a video, and play around with these three. You’ll thank yourself later. 🙌 👉 Also, here’s the official MDN documentation if you want to go deeper: 📘 https://lnkd.in/gPZcKwFX #JavaScript #ReactJS #WebDevelopment #FrontendDev #LearningInPublic #CodingJourney #map #filter #reduce

Day 25 of #100DaysOfCode – JavaScript Basics Today’s session with Harsh Vandana Sharma from Sheryians Coding School and Sheryians Coding School Community focused on understanding the fundamentals of JavaScript, its origin, evolution, and importance in web development. We learned that JavaScript was created by Brendan Eich in 1995 while working at Netscape, and it was developed in just 10 days. Over the years, JavaScript has gone through multiple versions, and among them, ES6 (ECMAScript 2015)is the most well-known. ES6 introduced modern features such as let, const, arrow functions, template literals, and classes. We also learned how to link JavaScript in an HTML file using the <script> tag — either internally within the document or externally through a .js file. JavaScript is an essential part of web development as it makes web pages dynamic, interactive, and functional, complementing HTML and CSS. It was also discussed that JavaScript is standardized by ECMA International, and the TC39 Committee is responsible for defining and maintaining the ECMAScript standards used across browsers. We explored three important variable declaration keywords — var, let, and const — and understood how they behave in JavaScript: var: Function-scoped, can be redeclared and updated. let: Block-scoped, can be updated but not redeclared within the same scope. const: Block-scoped, cannot be updated or redeclared, used for constants. Lastly, we learned how to use the console for debugging and displaying outputs: console.log() – For general output or messages. console.error() – For displaying errors. console.warn() – For showing warnings.

🚀 Day 26 of my Web Dev Journey Today at Cohort 2.0 (Sheryians Coding School), Harsh Vandana Sharma bhaiya introduced us to the history and basics of JavaScript, the language that powers the web 🌐 Here’s what I learned 👇 🧠 A little history • JavaScript was created by Brendan Eich while working at Netscape. • Amazingly, he built it in just 15-16 days 😲 • But because it was made so quickly, it had many issues and bugs, which were later fixed through multiple versions. • The biggest evolution came with ES6 (ECMAScript 6), a version that completely changed JS and made it much more powerful and modern. 💻 Why JavaScript matters • JavaScript (JS) is a scripting language, a way for humans to communicate with computers. • It brings life to websites, adding animations, interactions, and validations. • Practically every type of engagement on a webpage uses JavaScript. How JS runs • JavaScript was originally built to run inside browsers. • We can link JS files to HTML using the <script> tag. • You can also run JS directly in the browser console using Ctrl + Shift + I. Some basics we covered today: • Keywords: var, let, const • Console methods: console.log() → to print, console.error() → to show an error, console.warn() → to show a warning • User interaction:  prompt() → to take user input, alert() → to show an alert message Strings and their methods: • Anything inside quotes is a string. • Common string methods: .slice(), .replace(), .split(), .includes(), and template literals (backticks `, also known as template strings). Every session adds a new layer of understanding, and today was all about building the foundation for JavaScript 💪 Excited to dive deeper into this amazing language in the upcoming days! Stay tuned 🔥 ❤️ #WebDevelopment #Cohort2 #SheriansCodingSchool #LearningInPublic #HTML #CSS #FrontendDevelopment #BackendDevelopment #FullStackDevelopment #LearningJourney
