Unlock Console Power: Beyond console.log

A lot of people are shipping faster than ever, but when something breaks, most reach for AI instead of looking at what the browser is actually telling them. I wrote 5 DevTools features that most developers miss and never really used: → $0 and $_ console shortcuts → Network request blocking → Local Overrides → Rendering panel → Memory profiling Full breakdown is on my blog 👇 https://lnkd.in/g3w2GnDv #frontend #webdevelopment #devtools #javascript #programming

Hoisting and Closures are the exact points where JavaScript stops being a simple scripting language and demands that you understand its compiler architecture. If you don't understand how the V8 engine allocates memory, these behaviors look like bugs. Day 09/10 of JavaScript Series. . . . #javascript #tech #programming

I used to use var for everything. I thought let is just the "new version" of var. Same thing, right? Wrong. var is hoisted to the top of the function.   let stays inside the { } block. That's why everyone says: stop using var. let is not just "new var". It's safer var. Did you also use var for everything before? #javascript #coding #learnToCode

LeetCode Day 2 : Problem 80 (Remove Duplicates from Sorted Array II) Just solved another LeetCode problem. It was "Remove Duplicates from Sorted Array II", sounds similar to yesterday, right? But here's what I actually learned: My condition was more complex than it needed to be. I was checking against two positions when checking just one was enough. Always ask yourself, am I doing more work than the problem requires? I got confused seeing the full array in console.log and thought my answer was wrong. But LeetCode only checks the first k elements. Everything beyond that is ignored. Read the problem statement carefully. I worried about the runtime being 53ms. Turns out it didn't matter, the solution was already O(n), one pass, no extra space. LeetCode's runtime fluctuates every run due to server load. What matters is time and space complexity, not the ms number. Four problems in. The Two Pointer pattern keeps showing up. Same idea, slightly different condition each time. The real lesson? Don't overcomplicate the condition. And never judge your solution by ms, judge it by complexity. #DSA #LeetCode #JavaScript #CodingJourney #Programming

Just published a deep dive into how V8 handles arrays under the hood 🚀 Key takeaway: not all arrays are equal. Packed arrays (SMI/Double) and TypedArrays are highly optimized, while holey and mixed arrays introduce hidden performance costs due to extra checks and de-optimizations. If you're writing performance-critical JavaScript, these low-level details *matter more than you think*. I’ve also included a benchmark to see the differences yourself 👇 https://lnkd.in/gsxGFNZv #JavaScript #V8 #Performance #NodeJS #Programming

🚀 Day 22 of 180 — Longest Substring Without Repeating Characters ✅ LeetCode 3 — Longest Substring Without Repeating Characters Classic sliding window problem. Find the longest substring with all unique characters. Used a HashMap to store each character with its last seen index instead of frequency. This is the key difference from previous sliding window problems. Slide r through the string. If current character already exists in map AND its last seen index is within current window (>= l) — move l to one position ahead of that last seen index. This way the duplicate is removed from the window. Then update the character's index in map and calculate max window size. The tricky part — even if character exists in map, only move l if that character is actually inside the current window. If it's behind l already, no need to shrink. Day 22 done. 158 to go. 🔥 #180DaysDSA #Day22 #LeetCode #Java #DSA #SlidingWindow #HashMap #Strings #DSAJourney #CodingJourney #Programming #DataStructures #Algorithms #ProblemSolving #BuildInPublic #CodeNewbie #LearnToCode #100DaysOfCode #SoftwareDevelopment #Developer #StudentDeveloper #TechCommunity #LinkedInTech #CompetitiveProgramming
