I just finished watching Akshay Saini 🚀's latest deep dive into Promises, Async, and Await from the Namaste JavaScript series, and my mind is officially blown. 🤯 For the longest time, I understood how to use async/await, but I never truly grasped what happens behind the scenes. Akshay has a unique way of breaking down complex concepts—like how the JS engine "suspends" function execution without blocking the call stack—making it look so simple. Key takeaways that stuck with me: ✅ The difference between the "old" way (Promise chaining) vs. the "new" syntactic sugar. ✅ How await actually pauses the function execution while keeping the page responsive. ✅ Handling multiple promises and why the order of execution matters. If you are a developer looking to master JavaScript fundamentals, this video is an absolute must-watch. Huge thanks to Akshay Saini for putting in so much effort to create high-quality, free content for the community. You are making us all better engineers! 🙌 Check out the full video here #JavaScript #WebDevelopment #NamasteJavaScript #Frontend #Programming #Learning #AsyncAwait #TechCommunity #AkshaySaini Thanks to Akshay Saini 🚀 https://lnkd.in/gW5nXUaj

🚀 Day 15 of My #React Learning Journey – #Functional vs #Class #Components Today I explored the difference between Functional Components and Class Components in React. 🧠 #FunctionalComponents ✔ Simple JavaScript functions that return JSX ✔ No render() method required ✔ Use React Hooks for state & lifecycle ✔ Less code, easier to read and maintain ✔ Preferred in modern React development 🧠 #ClassComponents ✔ Must extend React.Component ✔ Requires a render() method ✔ Uses this.state for state management ✔ Lifecycle methods like componentDidMount() ✔ More boilerplate and complex structure ⚡ Key Differences 🔹 State Management Functional → useState (Hooks) Class → this.state 🔹 Lifecycle Handling Functional → useEffect Class → lifecycle methods 🔹 Code Complexity Functional → Simple & clean Class → More complex 🔹 Performance & Usage Functional → More efficient & widely used today Class → Older approach (still useful but less common) 💡 My Takeaway: Functional components with Hooks have become the standard way of building React applications due to their simplicity and flexibility. Excited to keep learning and building more with React! 💻✨ #React #JavaScript #FrontendDevelopment #WebDevelopment #ReactJS #LearningJourney #10000 Coders

🚀Day 103 of Cohort2.0 Today's class was about More on Instagram clone project with Ankur Prajapati at Sheryians Coding School In this session, I focused on integrating backend features into the frontend, ensuring a seamless connection between both layers of the application. I designed and implemented the UI for the feed, where posts from different users are displayed in a structured and user-friendly manner. Alongside this, I continued applying the four-layer architecture to maintain clean code practices to improve scalability. Additionally, I implemented the like and unlike functionality for posts, enabling users to interact with content in real time. Proper authentication checks were also incorporated, ensuring that only loggedin users can perform these actions, thereby enhancing both security and user experience, and maintain proper users data. This session further strengthened my understanding of full-stack development by bridging backend logic with frontend execution while maintaining a clean and scalable architecture. #responsiveness #responsivedesig #css #scss #html #Cohort2 #webdevelopment #Javascript #react #DOM #frontend

await Only Works With Promises & Thenable Objects - Here's Why This Matters 🚀 Post Content: One of the most common misconceptions about async/await in JavaScript is that await works with any value. It doesn't. The Truth: await only works with: Promises - the standard async pattern Thenable Objects - objects with a .then() method Why Does This Matter? Understanding this distinction helps you: Debug async code more effectively Know when to wrap values in Promise.resolve() Create custom thenable objects when needed Avoid silent failures in your async workflows Pro Tip: If you're awaiting a regular value, it returns immediately. If you need to ensure consistent async behavior, wrap it: await Promise.resolve(value) The more you understand the fundamentals, the better your async code becomes. 💪 #JavaScript #AsyncAwait #WebDevelopment #Promises #CodingTips #FrontendDevelopment #NodeJS #Programming #DeveloperLife #TechBlog #LearningToCode #CodeQuality

Common React Events Every Developer Should Know If you're learning React, understanding event handling is essential for building interactive user interfaces. Here are some of the most commonly used React events and when to use them. 1. onClick: Triggered when a user clicks an element. Commonly used for buttons, menus, and triggering actions. 2. onChange: Fires when the value of an input field changes. Mostly used in forms to capture user input. 3. onFocus: Occurs when an input field becomes active. Helpful for highlighting fields or showing hints. 4. onBlur: Happens when an input field loses focus. Often used for validation after the user leaves a field. 5. onMouseOver: Executes when the mouse moves over an element. Useful for hover effects, tooltips, or previews. 6. onMouseOut Triggered when the mouse leaves an element. Commonly paired with hover interactions. 7. onSubmit Invoked when a form is submitted. Used to handle form data before sending it to a server. 8. onKeyDown: Triggered when a keyboard key is pressed down. Useful for shortcuts or detecting specific keys. 9. onKeyUp: Fires when a keyboard key is released. Often used for live search or input validation. Why these events matter: React events allow developers to create dynamic and responsive applications by responding to user actions in real time. If you're learning React, mastering these events will make your UI much more interactive and user-friendly. #React #WebDevelopment #FrontendDevelopment #JavaScript #Coding #ReactJS #Programming

JavaScript Notes LinkedIn Chef Robotics The Leet Coder 🚀 Ever wondered what makes websites interactive? It’s not magic… it’s JavaScript 🧠 From login forms to live chats, from shopping carts to notifications — JavaScript is everywhere. If you want to become a developer in 2026, JavaScript is not optional… it’s essential. 💡 Start small: 👉 Validate a form 👉 Create a button click 👉 Build a mini project Consistency > Complexity #JavaScript #WebDevelopment #Coding #100DaysOfCode #Frontend #TechCareers #LearnToCode

Day 18 of my JavaScript learning journey 🚀 Today, I improved my Contact Form Validation project by making it more interactive and user-friendly. Instead of just showing errors on submit, I implemented real-time validation, so users get instant feedback as they type. Here’s what I added: • Live validation using onkeyup • Proper validation for: * Full name (format check with regex) * Phone number (digits + length check) * Email (pattern validation) * Message (minimum character requirement) • Dynamic error messages that update instantly • Visual success indicators (check icons ✔️) • Cleaner and more structured validation functions One thing I really noticed today is how much small UI feedback improves user experience. Now the form actually guides the user instead of just reacting after submission. I also started thinking more about how users interact with forms, not just how the code works.

🚀React Learning Series | Day 7 – Event Handling in React ->Event handling in React allows applications to respond to user actions such as clicks, typing, and form submissions. ->React events work similarly to JavaScript events but follow camelCase naming and use functions as event handlers. Common events include: --onClick --onChange --onSubmit --onMouseOver Example: function ButtonClick() { function handleClick() { alert("Button Clicked!"); } return <button onClick={handleClick}>Click Me</button>; } Explanation: --onClick triggers the function when the button is clicked --React updates the UI or performs actions based on user interaction Why Event Handling is Important: ✔ Builds interactive user interfaces ✔ Connects user actions with application logic ✔ Essential for forms and dynamic UI behavior --->Event handling is a key concept that makes React applications interactive and user-friendly. 📌 Day 7 of my React Learning Series #ReactJS #ReactDeveloper #FrontendDevelopment #WebDevelopment #JavaScript #CodingJourney #DeveloperJourney #LearningInPublic #BuildInPublic #TechLearning #LinkedInSeries 🚀
