How to simplify OTP interfaces for #WebDev teams

JavaScript — Bringing Life to the Web HTML gives the structure, CSS adds the style, but it’s JavaScript that brings your website to life! 💻✨ JavaScript adds logic, interactivity, and dynamic behavior to web pages — everything from a simple button click to a complex app runs because of it. 💡 Core JavaScript concepts every frontend developer should know: Variables — store data values (let, const, var) Functions — reusable blocks of code Events — respond to user actions like clicks or keypresses DOM Manipulation — change HTML and CSS using JS Fetch API / Async — handle APIs and asynchronous operations ES6 Features — arrow functions, template literals, destructuring, etc. “HTML is the body, CSS is the style, and JavaScript is the heartbeat of the web.” ❤️ #JavaScript #FrontendDeveloper #WebDevelopment #Coding #MERNStack #LearningJourney #JS

🧠 Understanding JavaScript Errors: A Guide for Every Developer Errors — every developer’s uninvited guest. If you’ve ever written JavaScript, you’ve definitely seen one of those intimidating red messages on your console. But don’t worry — they’re not enemies; they’re actually trying to help you write better code. 🔍 What Are JavaScript Errors? JavaScript errors occur when the code you write breaks the rules of the language or encounters an unexpected situation. The browser then stops executing the script and shows you what went wrong. ⚙️ Common Types of JavaScript Errors Here are the main categories of JavaScript errors: 1. Syntax Error This happens when you make a typo or violate JavaScript grammar. console.log("Hello World" // Missing closing parenthesis 🧩 Fix: Always check your brackets, commas, and semicolons. 2. Reference Error When you try to use a variable that hasn’t been declared. console.log(name); // name is not defined 💡 Fix: Make sure all variables are declared before using them. 3. Type Error Happens when you use a value in an inappropriate way. let num = 10; num.toUpperCase(); // ❌ numbers don’t have toUpperCase() ⚙️ Fix: Always check data types before performing operations. 4. Range Error When a value is outside the allowed range. let num = new Array(-5); // Negative array length 🧠 Fix: Validate user inputs and variable values. 5. Eval Error (Rarely used now) Occurs with incorrect usage of eval(). Modern JavaScript discourages its use for security reasons. 🛠️ Handling Errors with Try...Catch Instead of letting errors crash your program, you can handle them gracefully: try { let result = nonExistentFunction(); } catch (error) { console.log("An error occurred:", error.message); } This keeps your app running smoothly and gives you control over what happens when something breaks. 🚀 Final Thoughts Errors are not the end — they’re guides. Each error message teaches you something about your code and helps you grow as a developer. So next time you see one, take a breath, read carefully, and debug with confidence. #codecraftbyaderemi #webdeveloper #javascript #webdevelopment #frontend

We all know that large JavaScript bundles are a major performance killer. That "First Load JS" is what stands between your user and a great, fast experience. I was reading a great post by Kevin Wang that breaks down why this initial bundle is so critical. Every script your user has to download, parse, and execute "Before" the page is interactive is a bottleneck that hurts your Core Web Vitals. So, what's the most powerful tool in our toolbox to fix this? ----------------------- Next.js makes this incredibly easy with `dynamic imports`. The concept is simple: Don't load code until you need it. Instead of a normal, blocking import: `import MyBigModal from "../components/MyBigModal";` You import it dynamically (See the image below 👇🏻) ----------------------- With this change, the code for `MyBigModal` is completely left out of the initial page bundle. It's only fetched from the server "After" the user clicks the button. The key takeaway? - Ship only the code that's absolutely necessary for the initial view, and dynamically load the rest.

When you need to run a function repeatedly in JavaScript, your first thought is almost always setInterval. It's simple, and it's literally what it was made for. But for more complex, real-world scenarios, there's a powerful and often more robust alternative: 𝘂𝘀𝗶𝗻𝗴 𝗮 𝗿𝗲𝗰𝘂𝗿𝘀𝗶𝘃𝗲 𝘀𝗲𝘁𝗧𝗶𝗺𝗲𝗼𝘂𝘁. So, why would you choose this approach over the standard setInterval? There are two crucial reasons: ▪️𝗜𝘁 𝗴𝘂𝗮𝗿𝗮𝗻𝘁𝗲𝗲𝘀 𝗻𝗼 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 𝗼𝘃𝗲𝗿𝗹𝗮𝗽. A recursive setTimeout schedules the next call only after the current function's execution is complete. setInterval, on the other hand, doesn't care if the previous function has finished; it just tries to run every X milliseconds. If your task (like an API call) takes longer than the interval, you can end up with overlapping executions and unpredictable behavior. ▪️𝗜𝘁 𝗴𝗶𝘃𝗲𝘀 𝘆𝗼𝘂 𝗴𝗿𝗮𝗻𝘂𝗹𝗮𝗿 𝗰𝗼𝗻𝘁𝗿𝗼𝗹. Inside your recursive function, you can use conditional logic to decide if you should even schedule the next call. For example, you could stop the loop if an error occurs or a certain condition is met. setInterval is less flexible; it will schedule another call no matter what, until it's explicitly canceled from the outside. This doesn't even get into other nuances, like how most browsers throttle setInterval in inactive tabs, which can affect its precision. The point isn't to explore every edge case, but to highlight that a robust alternative exists. 𝗧𝗵𝗲 𝗼𝗯𝘃𝗶𝗼𝘂𝘀 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 𝗶𝘀𝗻'𝘁 𝗮𝗹𝘄𝗮𝘆𝘀 𝘁𝗵𝗲 𝗯𝗲𝘀𝘁 𝗼𝗻𝗲, and knowing which tool to use for your particular use case is key to building reliable software.

localStorage - One of the simplest yet most powerful browser features every front-end developer should master A Practical Guide to Using localStorage in JavaScript (With Mini Project) Richa Parekh ・ Nov 12 #javascript #web #learning #frontend https://lnkd.in/deeT7hpA

Recently, I built a website using HTML, CSS, and JavaScript just with a cleaner templating layer. Working on this project reminded me how much frameworks like Next.js or React handle behind the scenes, especially in terms of optimization. From image compression, lazy loading, and responsive images, to caching and minification every detail had to be thought through manually. It was a great reminder that sometimes, building from scratch helps you truly understand how the web works. You start seeing how small things image sizes, layout shifts, network requests impact performance and user experience. While frameworks make development faster, getting back to the basics sharpens your technical depth and appreciation for what’s happening under the hood. #WebDevelopment #Frontend #PerformanceOptimization #LearningByDoing #HTML #CSS #JavaScript

CSS-Only Scroll-State Queries for Dynamic Navigation ❌ No JavaScript needed! We can finally build context-aware navigation headers without a single line of JavaScript, thanks to the new CSS scroll-state query and the powerful scrolled state. The scrolled state tracks the last scroll direction, in contrast to the simpler scrollable queries. This makes it perfect for creating those slick, context-aware "sticky headers" that only appear when you're scrolling back up. 🎩 The "Hidey Bar" Effect with Pure CSS When scrolling down, the header hides itself. When scrolling back up, it reveals itself. All you need is the @container scroll-state(scrolled: bottom) query! Here is the essential code to hide a fixed header when you scroll down: html { container-type: scroll-state; } header { transition: translate 0.25s; translate: 0 0; /* Slide header up when last having scrolled towards the bottom */ @container scroll-state(scrolled: bottom) { translate: 0 -100%; } } What are your thoughts on this new CSS feature? Are you planning to use scroll-state queries in your next project? 𝗡𝗼𝘁𝗲 𝗼𝗻 𝗯𝗿𝗼𝘄𝘀𝗲𝗿 𝘀𝘂𝗽𝗽𝗼𝗿𝘁: This is a very new feature and still has limited support. As of now, it's available in Chrome 144+. caniuse: https://lnkd.in/dWFm-ckF Reference: Post by Bramus https://lnkd.in/dR69Z69a Code Demo by Bramus: https://lnkd.in/dYgceun8 #CSS #CSSTricks #Frontend #WebDevelopment #CodingTips #WebDev #CleanCode #itsmacr8
