How to control time in Cypress tests with cy.clock()

⚡ Post 2: "React Debugging = Detective Work" Debugging React isn't coding. It's being Sherlock Holmes 🕵️♂️. A slow render = a hidden Context issue A broken UI = a missing key An infinite loop = a sneaky useEffect dependency 💡 Pro Tip: Don't just code React… learn to debug React. That's where senior-level skill really shows. 👉 What's the hardest React bug you've ever solved? #AdvancedReact #WebPerformance #Frontend #CleanCode

Null Coalescing (??) ⚔️ Logical OR (||) 1️⃣ Null Coalescing (??) 💡 Use when: You want a default value if a variable is null or undefined, but not if it’s 0, "", or false. Example:  let userPreferredTheme = null; // User has not selected a theme let defaultTheme = "Light Mode"; let finalTheme = userPreferredTheme ?? defaultTheme; // Will fall back to "Light Mode" console.log(finalTheme); // Output: "Light Mode" 2️⃣ Logical OR (||) 💡 Use when: You want a default for any falsey value (null, undefined, 0, "", false). Example:  let customUsername = ""; // User intentionally left it blank username = customUsername || "Guest"; // Will fall back to "Guest" console.log(username); // Output: "Guest" ⚠️ Important Difference: • ?? only skips null or undefined values. • || skips any falsey value: 0, "", false, null, or undefined. 💬 When to Use Each? • Use ?? when you want to avoid null/undefined values but not treat 0, "", or false as invalid. • Use || when you want a fallback for any falsey value like "", 0, or false. #JavaScript #WebDevelopment #Coding #DevTips #Programming #Frontend #Developer

Ever hit ‘it works on my machine’… only to watch it fail in production? 😅💻 That was me recently while deploying a project. After pushing to Vercel, my npm run build kept failing. Frustrating at first but it became a valuable learning moment. 🔍 I dove into the logs, 🔧 fixed mismatched imports and default vs named exports, 🚀 refactored components for cleaner structure. Outcome: The build finally succeeded, and the app ran smoothly in production! 💡 Key takeaway: Production deployment teaches lessons development never will. Think deeply, debug methodically, and pay attention to the small details. #WebDevelopment #FrontendDevelopment #ReactJS #NextJS #Vercel #DeploymentChallenges #CodingLife #DeveloperJourney #ProgrammingTips #TechGrowth

𝗢𝗻𝗲 𝗱𝗼𝘁, 𝗼𝗻𝗲 𝗱𝗶𝗴𝗶𝘁, 𝗼𝗻𝗲 𝘀𝘆𝗺𝗯𝗼𝗹 𝗶𝗻 𝗽𝗮𝗰𝗸𝗮𝗴𝗲.𝗷𝘀𝗼𝗻, 𝘁𝗵𝗮𝘁’𝘀 𝗮𝗹𝗹 𝗶𝘁 𝘁𝗮𝗸𝗲𝘀 𝘁𝗼 𝘁𝘂𝗿𝗻 𝗮 𝘀𝗺𝗼𝗼𝘁𝗵 𝗱𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁 𝗶𝗻𝘁𝗼 𝗮 𝗹𝗮𝘁𝗲-𝗻𝗶𝗴𝗵𝘁 𝗱𝗲𝗯𝘂𝗴𝗴𝗶𝗻𝗴 𝘀𝗲𝘀𝘀𝗶𝗼𝗻. 🚀🔧 So most of the devs would be knowing in this era what is package.json. In that if you observe version numbers look like this: 𝗠𝗔𝗝𝗢𝗥 · 𝗠𝗜𝗡𝗢𝗥 · 𝗣𝗔𝗧𝗖𝗛 For example "express": "4.18.2" Here 4 is Major, 18 is Minor and 2 is Patch MAJOR (first digit) → Breaking changes Example: 3.x.x → 4.0.0 (might break compatibility) MINOR (middle digit) → New features (backward compatible) Example: 4.17.x → 4.18.0 PATCH (last digit) → Bug fixes (backward compatible, no new features) Example: 4.18.1 → 4.18.2 🎭 Special characters before versions When you see symbols like ^ (caret) or ~ (tilde), they tell npm how flexible it should be when installing versions. 1. Caret (^) Example: "lodash": "^4.17.21" Meaning: Accept updates that don’t change the major version. i.e., >=4.17.21 and <5.0.0 👉 Safe for most apps because minor and patch updates usually don’t break things. 2. Tilde (~) Example: "lodash": "~4.17.21" Meaning: Accept updates that don’t change the minor version. i.e., >=4.17.21 and <4.18.0 👉 Locks it tighter than ^, allowing only patch updates. 3. No symbol Example: "lodash": "4.17.21" Meaning: Install exactly version 4.17.21 👉 So in short: 1. ^ = allow new features & fixes (safe within major version). 2. ~ = allow only bug fixes (safe within minor version). 3. Exact number = lock to one version. #JavaScript #NodeJS #WebDevelopment #SoftwareEngineering #packagejson #CodingTips #CleanCode #DevCommunity #SemanticVersioning #SoftwareDevelopment #DeveloperLife

👨💻 From a web developer’s perspective, every bug, crash, or performance bottleneck isn’t just a headache—it’s an opportunity. Each problem pushes us to think deeper, code smarter, and architect better. The real challenge isn’t just writing code, but building solutions that scale, adapt, and last. Great developers don’t just fix issues; they anticipate them. 🚀 #SoftwareDevelopment #CodingLife #ProblemSolving #DevCommunity #Innovation #coder #programmer

🚫 Don’t be the developer who just rethrows errors. When you catch an error only to throw it again… you’re not helping anyone, you’re just adding noise. ✅ A cleaner approach: Let the lower-level function (createUser) fail naturally. Handle the error where it actually matters (handleSubmit). This is the right place to log, show UI feedback, or trigger analytics. This keeps your code simple, maintainable, and developer-friendly. Remember: Good error handling is about context, not clutter. 💬 What’s your strategy for handling errors in your projects? #JavaScript #CleanCode #Programming #React #FrontendDevelopment #BestPractices
