Debug Node.js with Lens: A Powerful UI Tool

That tiny newline between tags sneaks a space into your markup. Two sibling <span> elements sit on separate lines inside a <div>. No explicit space character is added. A stray gap appears in tightly packed UI components. Automated snapshot tests fail with mismatched markup. Customers report misaligned buttons in live deployments.

A React component logs a surprise string even though a default prop is defined. The component uses destructuring with a fallback value and also sets defaultProps. It gets invoked directly as a regular function, not via JSX. In production this can mask missing props, leading to silent bugs. Logs may mislead you during debugging sessions. Automated tests that call the component as a function could pass falsely. Comment A, B, C, or D with the string you think will be logged and defend your choice. #tsx #React #Programming #Backend #CodingInterview

Stop using console.log like this 👇 If you’re logging arrays or objects like this: console.log(users); It often looks messy and hard to read 😵💫 Try this instead: console.table(users); You’ll get a clean table view in the console ✨ I started using this recently, and it makes debugging much faster. Small trick… big difference 🚀 Have you tried this before? #JavaScript #FrontendDeveloper #WebDevelopment #Debugging #Programming

💡 C++ Insight — Day 4/100 Most developers get this wrong 👇 int a = 10; int b = a++; std::cout << a << " " << b; What’s the output? 👉 a = 11, b = 10 Why? a++ is post-increment → use first, then increment. int c = ++a; // pre-increment → increment first, then use a++ → use → then increase ++a → increase → then use #CPP #CPlusPlus #Programming #CodingInterview #100DaysOfCode #Developers #CodingTips #TechCommunity #LearnCPP #SoftwareEngineering #EmbeddedSystems #CodeNewbie

DAILY REMEMBRANCE Opaque Return Types (some) Opaque return types, denoted by the some keyword, allow a function to return a specific, concrete type while hiding that type's identity from the caller. The compiler retains knowledge of the underlying type, but the caller only knows the value conforms to a specific protocol. Fixed Identity Unlike a generic return or a protocol type (any), an opaque type must resolve to exactly one concrete type for all possible return paths within a specific function. Reverse Generics In a standard generic function, the caller decides the type. With opaque types, the function implementation decides the type. Performance Because the compiler knows the underlying type at compile time, it can perform optimizations (like inlining) that are not possible with existential types (any). Usage in SwiftUI Opaque types are fundamental to SwiftUI. The body property of a View uses some View. This allows the view hierarchy to be complex and nested while providing the compiler with the specific type information needed to efficiently calculate UI diffs. #Swift #SwiftLang #SwiftUI #iOSDevelopment #iOSDev #Programming #SoftwareDevelopment

#C++ #MovieTheaterTicketSystem 🎬 I built a menu-driven Ticket System in C++ to practice OOP, linked lists, and input validation. Features implemented: -Add Tickets : store genre, sold status, and price. -Show Tickets : display all tickets with unique IDs and sold status. -Refund Tickets : search by ID and update status. -Memory Management : dynamic linked list nodes deleted safely. -Input Validation : prevents invalid sold status entries. #Key learnings: Using classes, static members, and constructors for unique IDs. Traversing and manipulating linked lists. Structuring code with functions (addTicket(), showTicket(), refundTicket()). Implementing a menu system with switch statements. #Next #improvements planned: -Prevent negative prices and invalid inputs. -Map ticket codes to full genre names. -Save/load tickets to a file for persistence. -Add filtering/sorting tickets by genre or price. #cplusplus #programming #beginnerprojects #oop #linkedlists #coding #learningtocode #cplusplusprogramming #menuprogram #codepractice #dynamicmemory

A zero value can leak into your UI. You write `{count && <span>Visible</span>}` assuming falsy values hide the element. But count equals 0. Stray zeros appear in production screens. Logs get polluted with unexpected digits. Debugging time spikes chasing phantom output. Comment A, B, C, or D and defend your choice. #JSX #React #Programming #CodingInterview

NullReferenceException is one of the most common and most avoidable runtime crashes in .NET. C# 8 introduced Nullable Reference Types (NRT) to fix this at the compiler level, not at 3 am in production. Here's everything you need to know to enable them, use them correctly, and avoid the common pitfalls. What's been your experience migrating a legacy codebase to NRT?  Drop it in the comments.  #dotnet #csharp #softwaredevelopment #dotnetdeveloper #csharpdev  #cleancode #programming #backend #webdevelopment #devtips
