Sending object as fetch POST body without JSON.stringify() and Content-Type

A Promise in JavaScript is an object that represents the future result of an asynchronous operation. It is used to handle tasks that take time, such as: 1. Fetching data from an API 2. Reading a file 3. Database operations 4.

An arrow function is a shorter and modern way to write functions in JavaScript, introduced in ES6.

The modern Java switch is underrated. I always use it in this new way because: The new switch is no longer just an alternative to if-else, but an expression that is cleaner, safer and more convenient for mapping values in modern code. Modern switch is: 1. Fewer errors No more forgotten breaks → no accidental fall-through. 2. Can be written as an expression Assign the result directly: 3. Support for multiple values case ‘OK’, “SUCCESS” -> ‘Success’; 4. Can use blocks with 'yield' Use `yield` when you need to add any logic to a `case` statement other than returning a result, such as logging, additional calculations or conditions switch is not just a statement, but an expression — and this significantly changes its capabilities. #Java #Backend #Developer #JavaDevelompent #Software #Programming

There are 10 things you MUST know as a programmer: 1) How to handle exceptions and error cases 10) How to understand binary For 10, this isn't the post for you. But for 1), I got you covered. I've put together a series of videos that should help you when working with errors in C#. While many of these examples are C# specific, you may find the explanations valuable if you work in other languages and tech stacks. Check them out here: - Understanding Try/Catch/Finally: https://lnkd.in/gr3Ad9zD - Exploring Result Types: https://lnkd.in/ghbkrYhc - How to NOT Throw Exceptions: https://lnkd.in/gr8xMuGz - Fail Fast or Be Defensive: https://lnkd.in/gh_xMbRW - Global Exception Handlers: https://lnkd.in/gmvnzRyr - Error Middleware in ASP NET Core: https://lnkd.in/g5Hm_6_4 If you want to stay up to date, you can make sure you bookmark this playlist: https://lnkd.in/gvKWe9Ds After this, the only error you should have to worry about is how to stop using JavaScript.

Most Java developers use only 30% of their debugger. Here are 5 debugging hacks that can instantly make you faster: Using tools like: 1️⃣ Conditional Breakpoints Instead of stopping 1000 times in a loop, add a condition: i == 499 This stops only when it matters. 2️⃣ Evaluate Expression (Alt + F8) Paused at a breakpoint? Try: user.getEmail() This allows you to test logic without restarting. 3️⃣ Exception Breakpoint Add a breakpoint for NullPointerException. The debugger stops exactly where it’s thrown. 4️⃣ Drop Frame If you’ve stepped too far, you can restart the current method without restarting the app. 5️⃣ Watch Variables Track orders.size() or object state live during execution. Debug smarter, not longer. Which one are you already using? #Java #Debugging #BackendDevelopment #SpringBoot #SoftwareEngineering #Developers #CodingTips #TechCareer

In Java, List is an interface from the Collection Framework  that represents an ordered collection (sequence). #white-It allows: 1.Duplicate elements 2.Insertion order maintained 3.Index-based access List belongs to: java.util package. . . . . . . . . . #java #python #programming #javascript #coding #programmer #html #developer #css #coder #php #computerscience #software #code #indonesia #webdevelopment #webdeveloper #softwaredeveloper #technology #codinglife #linux #webdesign #development #tech #programmingmemes #softwareengineer #pythonprogramming #programmers #javaprogramming #hackforge

Solved the “Mini-Max Sum” problem on HackerRank using JavaScript. The challenge was to calculate the minimum and maximum sums by summing exactly four out of five integers. Key takeaways: • Use reduce for total sum and Math.min/Math.max for efficiency • Avoid redundant computations by skipping largest/smallest number • Attention to output formatting (space-separated, single line) Small problems, strong fundamentals. Consistency > Intensity. #HackerRank #JavaScript #ProblemSolving #Algorithms

✨DAY-15: 🔌 Interfaces in Java – Real-World Example Made Simple! Ever wondered how interfaces actually work in real life? Think about a power socket. ⚡ Different devices like: 🍞 Toaster 💻 Laptop 📱 Charger All plug into the same socket — but each device works differently. That’s exactly how Interfaces in Java work. 👇 interface Socket { void plugInDevice(); } Any class that implements this interface must define how plugInDevice() works. ✔️ Toaster → heats bread ✔️ Laptop → powers system ✔️ Charger → charges phone Same interface. Different implementations. Consistent structure. 💡 Why Interfaces Matter: Achieve 100% abstraction Enable multiple inheritance Promote loose coupling Improve scalability and flexibility The beauty of interfaces is simple: Different systems can connect through the same contract. Write once. Implement differently. Scale confidently. 🚀 #Java #OOP #Interfaces #Programming #SoftwareEngineering #CodingLife #TechConcepts #Developers

🚀 C# Feature Every Developer Should Know — Nullable Types One common cause of bugs in many languages is the Null Pointer Exception. C# provides powerful features to handle this safely and cleanly. 🔹 Nullable Value Types Normally, value types cannot be null. But by adding ?, they can hold null. int? age = null; // Nullable<int> bool? done = null; 🔹 Null-Coalescing Operator ?? Provide a default value if null. int result = age ?? 0; // if age is null, result = 0 🔹 Null-Conditional Operator ?. Safely access members without throwing exceptions. string? str = null; int len = str?.Length ?? 0; // no NullReferenceException 🔹 Null-Forgiving Operator ! Tells the compiler “I know this isn't null.” string definite = str!; // use carefully 🔥 Quick Tip The ?? and ?. operators are powerful C# features. Other languages like Java use Optional, but C# provides a much cleaner and concise syntax. #CSharp #DotNet #DotNetDeveloper #Programming #SoftwareDevelopment #BackendDevelopment #FullStackDeveloper #Coding #DeveloperLife #SoftwareEngineer #TechCommunity #CleanCode #CodingTips #LearnToCode
