Learned about object literals in JavaScript today. Easy to organize data and access values.

🚀 Starting My JavaScript Revision Journey! Body: Yesterday, I went back to the basics of JavaScript to strengthen my foundation. Here’s what I revised: 🟡 Variables — var, let, and const and when to use them 🟡 Scope — Global variables (accessible everywhere) — Local variables (accessible within a function/block) 🟡 Data Types — Primitive: string, number, boolean, null, undefined, symbol, bigint — Non-Primitive: objects, arrays, functions It’s amazing how revisiting fundamentals clears a lot of confusion!

🚀 JavaScript Practice: Prime Numbers from 1 to 100 Here's a simple yet classic logic-building problem — finding all prime numbers between 1 and 100 using JavaScript. Key learnings from this program: ✅ Nested loops usage ✅ Logical thinking with condition checks ✅ Introduction to algorithmic problem-solving 💡 Tech Used: JavaScript 👨💻 Concept: Prime Number Detection #JavaScript #Coding #100DaysOfCode #SoftwareEngineer #LearningInPublic #LogicBuilding #FrontendDevelopment

🧠 JavaScript Concepts I Explored Today Today was a solid learning session — I spent time understanding how functions actually shape the logic in JavaScript. Here’s what I went through 👇 Functions and how they make code reusable First-class and higher-order functions (functions inside functions 🔁) Closures — the part where JS “remembers” variables even after execution IIFE — functions that run instantly (good for isolated scopes) Arrays — map, filter, reduce, forEach Objects — destructuring, looping, optional chaining These concepts connected so many dots for me. The more I write JavaScript, the more I realize how expressive it can be when you actually understand the “why” behind the syntax. #JavaScript #CodingJourney #WebDevelopment #Frontend #MERNStack

🚀 Exploring JSON methods in JavaScript! I’ve shared a simple demo that shows how to: Convert a JSON string into a JavaScript object using JSON.parse() Convert a JavaScript object back into a JSON string using JSON.stringify() Check out the full implementation on GitHub: 🔗 https://lnkd.in/dK2fajsP #JavaScript #FullStack #100xDevs #WebDevelopment #Coding #100DaysOfCode

💻 Day 3 of #100DaysOfCode > 🚀 Today I learned about JavaScript Loops — one of the most powerful concepts for repeating tasks! 🔁 The 5 main types of loops in JavaScript: 1️⃣ for loop 2️⃣ while loop 3️⃣ do...while loop 4️⃣ for...of loop 5️⃣ for...in loop 💡 Loops make our code efficient and clean by reducing repetition. #100DaysOfCode #JavaScript #WebDevelopment #CodingJourney #FullStackDeveloper

💡 Understanding Object Methods in JavaScript Working with objects is fundamental in JS. Here's a quick overview of some powerful methods: Object.keys(obj) → Returns all keys of the object. Object.values(obj) → Returns all values of the object. Object.entries(obj) → Returns key-value pairs as arrays. obj.hasOwnProperty("property") → Checks if the object has a specific property. Object.assign({}, obj, { newProperty: "newValue" }) → Creates a new object by merging existing ones. 👉 View the full example on GitHub: https://lnkd.in/dDN-vDkD #JavaScript #FullStack #100xDevs #WebDevelopment #Coding #JSConcepts #LearnJavaScript

🎯 Day 1 — Deep Dive into JavaScript Fundamentals Today I started my journey to strengthen the core of JavaScript, and it’s amazing how much depth lies behind the basics! 🚀 Here’s what I learned today: 🧩 Primitive vs Reference Types 🧠 typeof Operator Behavior ⚖️ Difference Between null and undefined 🪄 var vs let vs const and Variable Hoisting ⛔ Temporal Dead Zone (TDZ) 📦 Block Scope vs Function Scope 🔄 Implicit vs Explicit Type Conversion ✅ Truthy and Falsy Values 🔍 Comparison Operators & Type Coercion 🔧 Object to Primitive Conversion (valueOf, toString) 👇 Understanding this in Different Contexts: Global Context Object Methods Constructor Functions Arrow Functions Event Handlers Explicit & Implicit Bindings new Keyword Every topic connected like a puzzle — learning how JavaScript really works behind the scenes makes it even more exciting to code. 💻 #JavaScript #WebDevelopment #Day1 #LearningJourney #Frontend #Coding

JavaScript Unique Magic: Hoisting Definition: Hoisting in JavaScript means moving all variable and function declarations to the top of their scope before the code runs. This allows you to use a function or variable even before it is written in the code. Why It Happens: JavaScript interpreter reads the entire code first and sets up memory for all variables and functions. That why you can access them before their actual line of code appears. Uses: 1) Helps in calling functions before they are defined. 2) Makes code organization flexible. Problems: 1) Can cause confusion for beginners. 2) Variables declared with var become undefined if used before declaration. 3) let and const declarations cause an error if used too early #JavaScriptMagic #CodingTips #LearnJS #FrontendFun #ProgrammingLife #JSBeginners #WebDev #TypeScript #CodeSmart #DeveloperCommunity

💡 JavaScript LeetCode Challenge — Day 19: Longest Common Prefix 🚀 Today’s Challenge: Find the longest common prefix among an array of strings. 🧩 Problem Example: Input: ["flower", "flow", "flight"] Output: "fl" If no common prefix exists, return "". 💭 Key Takeaways: Improved understanding of string manipulation in JavaScript Practiced prefix trimming logic using indexOf() and slice() Every solved problem = better problem-solving muscle 💪 📈 #Day19 #JavaScript #LeetCode #CodingChallenge #100DaysOfCode #WebDevelopment #ProblemSolving #LearningInPublic #CodeNewbie

🚀 Day 1 of My 30 Days of JavaScript Challenge 🧩 Problem: Create Hello World Function (LeetCode #2667) Write a function createHelloWorld that returns a new function which always returns "Hello World", no matter what arguments are passed. 💻 Language: JavaScript ❓ Question: https://lnkd.in/eVgQ9W87 💡Solution:https://lnkd.in/ed7AXEYr 🧠 Concept Used: JavaScript closures and higher-order functions Demonstrates how a function can return another function 📚 Takeaway: A simple yet powerful reminder that understanding function behavior and scope is key in JavaScript. Every small step builds stronger fundamentals! #JavaScript #LeetCode #30DaysOfCode #CodingChallenge #WebDevelopment #FrontendDevelopment #100DaysOfCode
