## DAY 2 — Captcha Generator Day 2/30: Built a Captcha Generator from scratch. It creates randomized text and validates user input against it. No libraries, no APIs — just canvas rendering and string manipulation. The tricky part: making the captcha distorted enough to be hard to OCR but readable enough for humans. Turns out that balance is harder than it sounds. 🔗 Live: https://lnkd.in/gPzprnKc   🔗 Code: https://lnkd.in/gbqKTYrp #30DaysOfCode #JavaScript #WebDevelopment #BuildInPublic #WomenInTech

LeetCode Problem: Longest Common Prefix What I Learned: • How nested loops simulate 2D comparison (character index vs string index) • Comparing each string character with the first string as a reference • Using the OR operator (||) to handle multiple stopping conditions • Understanding short-circuit evaluation to prevent unnecessary checks • How .slice(0, i) extracts the valid prefix before mismatch • Why return immediately stops the entire function execution • Handling edge cases like complete match or no common prefix • Writing an efficient O(n × m) solution using simple iteration logic Problem Summary: You’re given an array of strings and need to find the longest common prefix among them. The core idea is: Compare each character of the first string With the same position in all other strings. If: • A string becomes shorter • OR characters don’t match → Stop immediately and return the prefix until that index. If no mismatch is found after full iteration → return the entire first string. This problem strengthened my understanding of control flow, string indexing, and early returns in JavaScript. A great example of breaking execution at the right time instead of overcomplicating logic. #100DaysOfLeetCode #leetcode #javascript #problemsolving #codingjourney #DSA #StringManipulation #AlgorithmicThinking Link: https://lnkd.in/gnvmJK-r

I was today years old when I found this out 😂 You can actually use Live Expressions inside Chrome DevTools. Click the "👁" icon in the Console to create a Live Expression. It evaluates your JavaScript expression automatically every ~250ms. Super useful for watching: - Variable changes - DOM state - Timers - Scroll position - FPS metrics #html #ai #coding #javascript #webdevelopment

I thought I understood map(), filter() and reduce()… until I wrote their polyfills. We use these methods daily in JavaScript. But I wanted to understand what actually happens behind the scenes. Building polyfills is one of the best ways to master: 1️⃣ Prototypes: How inheritance actually works in JS. 2️⃣ Execution Context: Mastering the behavior of this. 3️⃣ Edge Cases: Handling reduce() accumulators without an initial value. I’ve put together a deep dive into these internals. What’s inside: The logic behind Array.prototype. Step-by-step custom implementations. The "hidden" index logic in .reduce(). Which polyfill was the hardest for you to learn? Let’s discuss below! #Javascript #Chai aur Code #Polyfills

🚀 Day 1 of JavaScript Pattern Practice! Today I practiced building a simple star pattern using JavaScript functions. Patterns are a great way to improve your logic and get comfortable with loops. Here's the code I wrote: // Function to print star pattern function printStars(rows) { for (let i = 1; i <= rows; i++) { console.log('*'.repeat(i)); } } // Call the function printStars(4); Output: * ** *** **** ⭐ Key Learnings: Using for loops to control rows Using string.repeat() to create repeated characters Functions help in reusing code easily Looking forward to learning more patterns in the coming days! 💻 #100DaysOfCode #JavaScript #Coding #FrontendDevelopment #Patterns #LearnToCode

The hell of parsers. One day, you think you’ve written a simple unit test. The next day, you realize you’ve opened a crack in the geometry of JavaScript. I was testing what felt like a safe invariant: source code → structure → source code. No transformation. No creativity. Just fidelity. And yet, something vanished. No error. No crash. No warning. Just a quiet absence. That’s when you learn the hard lesson: in JavaScript, structure is not always where you expect it to be. Some constructs don’t live inside what they initialize. They orbit it. Parsers rarely fail loudly. They fail silently and structurally. And once you see it, you can’t unsee it. Welcome to the hell of parsers. #Programming #JavaScript #Parsing #AST #Compilers #SoftwareEngineering #SystemsThinking #DeveloperLife #DeepTech #UnderTheHood

I built this animation using pure JavaScript and mathematical logic — no libraries, no frameworks. Everything you see — the motion, transitions, and color shifts — is driven by mathematical formulas and core JavaScript fundamentals. This project reminded me of something important: When you truly understand the fundamentals, you don’t need heavy tools to create something powerful. Math + Logic + Creativity = Limitless possibilities. #JavaScript #WebDevelopment #Frontend #CreativeCoding #Programming here is the code let t = 0;    function setup() {  createCanvas(400, 400);  colorMode(HSB, 360, 100, 100, 100);  strokeWeight(1); }    function organism(x, y) {  let k = 5 * cos(x / 14) * cos(y / 30);  let e = y / 8 - 13;     let d = pow(mag(k, e), 2) / 59 + 4;     let angleTerm = atan2(k, e);  let q = 60 - 3 * sin(angleTerm * e);     let wave = k * (3 + 4 / d * sin(d * d - t * 2));     let c = d / 2 + e / 99 - t / 18;     let xCoord = (q + wave) * sin(c) + 200;  let yCoord = (q + d * 9) * cos(c) + 200;  // 🎨 Only color added — no motion changes  let hue = (200 + d * 15 + t * 40) % 360;  let sat = 90;  let bri = 80;     stroke(hue, sat, bri, 80);  point(xCoord, yCoord); }    function draw() {  background(9);  // ← same as your original  t += PI / 20;  // ← same speed     for (let i = 0; i < 10000; i++) {   let x = i % 80;   let y = i / 43;   organism(x, y);  } }
