Debugging Made Easy: Finding the Culprit in Logs

Here we are again with another principle from The Pragmatic Programmer — EXCEPTIONS 📘 One of the problems with exceptions is knowing when to use them. Are they meant for every error? No, They should be used only for unexpected situations — the things that break your assumptions. If something is part of normal program behavior — like: • A user entering invalid input • Searching for a record that might not exist • Checking if an optional file is present That’s normal flow. Handle it with regular conditions (if/else, return values). That’s just your program doing its job. But if something happens that breaks a core assumption — like: • A configuration file that is guaranteed to exist is suddenly missing • A database connection fails unexpectedly • A critical dependency crashes That’s exceptional. That’s when you use an exception. A simple mindset shift helped me: Exceptions are not traffic lights controlling normal flow. They’re fire alarms 🚨 — you use them when something that should never happen actually happens. #programming #softwaredevelopment #cleancode #coding #bestpractices #pragmaticprogrammer #javascript #php #softwareengineering

The Power of Iteration, the Art of the Loop 🔄 In programming, if you have to do the same thing twice, you’re doing it wrong. Today was all about efficiency and automation as I dove deep into JavaScript Loops. What I covered today: ✔️ The Logic of Iteration ✔️ The "For" Loop ✔️ The "While" & "Do-While" Loops ✔️ Control Flow ✔️ Problem Solving 📢 You can check out my GitHub repo in comment. #JavaScript #CodingJourney #WebDevelopment #Loops #BangladeshDevelopers

Control Flow is not just a programming concept — it’s how our logic actually moves inside the code. In this article, I explained If, Else, Else-If, Nested If-Else, and Switch in a simple and relatable way using real-life examples. Understanding control flow is very important because it builds the foundation of decision-making in JavaScript. 👉 Read here:  https://lnkd.in/dypvmNKP Big thanks to Hitesh Choudhary , Piyush Garg and Akash Kadlag for making complex JavaScript concepts easy to understand through Chai Aur Code Their teaching style really helps in building strong fundamentals. Would love your feedback on the article 🙌 #JavaScript #ControlFlow #WebDevelopment #ChaiAurCode #LearningInPublic #CodingJourney

When Order Breaks: Detecting the Swap in a BST 🌳 Solved LeetCode 99 - Recover Binary Search Tree using inorder traversal. Since inorder traversal of a BST should produce a sorted sequence, the anomaly becomes visible when two nodes are swapped. By tracking the previous node during traversal, it’s possible to spot the violations and recover the tree without rebuilding it. Key takeaway: Many BST “fixing” problems reduce to finding where sorted order breaks. Traversal invariants are powerful debugging tools. Another solid step in sharpening tree intuition. #LeetCode #DSA #BinarySearchTree #TreeTraversal #JavaScript #ProblemSolving #LearnInPublic #DeveloperJourney

Most people use Dynamic Programming too early. Not every problem is DP. Before jumping into memoization, ask: • Can it be solved with greedy? • Is the input sorted → two pointers? • Can prefix sums simplify it? • Is brute force actually enough? DP is powerful. But unnecessary DP is overengineering. Strong problem solvers simplify first. Then optimize. That’s the real DSA maturity. - CodeWithIshwar #DSA #DynamicProgramming #ProblemSolving #SoftwareEngineering #CodingInterview #FrontendDevelopment #ReactJS #CodeWithIshwar

🚀 How JavaScript Executes Your Code — Behind the Scenes  Here’s the real flow. 👉 1. Parsing (Before code runs) Your code is first checked for errors and converted into a Syntax Tree (AST). 👉 2. JIT Compiler JavaScript uses a Just-In-Time compiler. It reads your code and prepares it for execution. 👉 3. Bytecode → Machine Code The engine converts your code into bytecode, then into machine code (CPU language). 👉 4. Execution Finally, the machine code runs and your program starts working. So the pipeline looks like this: Code → Parsing → Syntax Tree → JIT Compiler → Bytecode → Machine Code → Execution Keep learning. Keep building. 💪 #JavaScript #WebDevelopment #FullStackDevelopment #MERN #Programming #Developers #Learning #CodingJourney

📌 #62 DailyLeetCodeDose Today's problem: 190. Reverse Bits – 🟢 Easy Bitwise operations, yeah, i know... But actually there is nothing complicated here, we just don't use such operators very often (or don't use it at all :D) Here all operators used in this problem: & – Bitwise AND Compares each bit of two numbers. Returns 1 only if both bits are 1. ex. 5 & 1 (0101 & 0001) → 1 | – Bitwise OR Compares each bit of two numbers. Returns 1 if at least one bit is 1. ex. 4 | 1 (0100 | 0001) → 5 << – Left Shift Shifts all bits to the left. Adds 0 on the right. 🐗 Equivalent to multiplying by 2. ex. 3 << 1 (0011 → 0110) → 6 >>> – Unsigned Right Shift Shifts bits to the right. Adds 0 on the left (ignores sign). ex. 8 >>> 1 (1000 → 0100) → 4 https://lnkd.in/eRJHfQQw #DailyLeetCodeDose #LeetCode #JavaScript #Algorithms #ProblemSolving #Coding

Most TypeScript bugs aren't type errors. They're copy-paste errors. I see this in almost every codebase: You define a model. Then copy fields into a Create type. Then copy them again into an Update type. Three types. Same fields. Three places to maintain. It works… until someone adds a new field to the base model and forgets to update the others. No compiler error. Just a silent bug slipping into production. The fix? TypeScript's built-in utility types (check the image ↓) Two lines → all related types update automatically. No drift. No missed fields. No duplication. Small pattern. Massive reliability upgrade. Hope this helps someone. Save it for later. ♻️ #TypeScript #CodingTips #SoftwareEngineering #CleanCode #Programming

Stop debugging in silence. 🔇 I created a new extension called "Faah!" to add some necessary flair to your workflow. It triggers the iconic "Faah!" sound effect the moment your code hits a wall. Whether it's a failed mvn test, a crashed build, or those soul-crushing YAML indentation errors. Adding a little personality to the grind, one error at a time. 💻✨ 💻 VS Code Extension Link: https://lnkd.in/gXXpXrdv 🕸️ Github: https://lnkd.in/g5Sghczi Check it out!
