📌 #Day 28 / 100 – JavaScript (Part 8) ✅ Today I learned and practiced advanced JavaScript array and ES6 concepts and implemented them by solving assignment questions. Topics & their use (short): • Arrow Functions – Write concise and readable functions • map() – Transform each element of an array • filter() – Get elements that satisfy a condition • every() / some() – Validate conditions on arrays • reduce() – Reduce array into a single value (sum, average) • Spread Operator (...) – Merge or copy arrays and objects • Rest Operator (...) – Handle multiple function arguments • Destructuring – Extract values from arrays & objects easily • Default Parameters – Set fallback values for function inputs ✅ Assignment Questions Practiced: Q1. Square and sum array elements using arrow functions and find the average. Q2. Create a new array using map() by adding 5 to each element. Q3. Convert all words of an array into uppercase. Q4. Create doubleAndReturnArgs() to double extra arguments and merge with array. Q5. Create mergeObjects() to combine two objects into one. Practicing concepts with real questions for stronger fundamentals 🚀 Day 28 complete ✅ 👍🏻 #Day28 #JavaScript #ArrayMethods #ES6 #Practice #100DaysOfCode #WebDevelopment

🔹ES6 Features — Writing Clean & Modern JavaScript ES6 (ECMAScript 2015) changed the way JavaScript is written. If you’re still using old syntax, your code works — but it’s not industry-ready. 1️⃣ let & const (Better Variables) let count = 1; const PI = 3.14; ✔ Block-scoped ✔ Prevents accidental reassignments ✔ Cleaner than var 2️⃣ Arrow Functions const add = (a, b) => a + b; ✔ Shorter syntax ✔ No confusion with this ✔ Widely used in React 3️⃣ Template Literals const name = "JavaScript"; console.log(`Welcome to ${name}`); ✔ Readable ✔ No messy string concatenation 4️⃣ Destructuring const user = { name: "Alex", role: "Dev" }; const { name, role } = user; ✔ Clean data extraction ✔ Common in API responses 5️⃣ Spread & Rest Operators const nums = [1, 2, 3]; const newNums = [...nums, 4]; ✔ Safe copying ✔ Used heavily in React state updates 6️⃣ Why ES6 is Important ✔ Improves readability ✔ Reduces boilerplate code ✔ Makes JavaScript scalable ✔ Mandatory for frameworks #ES6 #ModernJavaScript #FrontendDevelopment #JavaFullStack #WebDevSkills #LearnToCode #PlacementReady

No frameworks. No libraries. Just HTML, CSS, and JavaScript. I built a small Todo List app to revise my fundamentals—and it turned out to be a great learning experience. From login & signup flows to task management using localStorage, this project reminded me why basics matter so much. Every button click, every DOM update, every bug fixed added clarity. Sometimes the best way to grow is to slow down and build simple things well. Back to basics, but moving forward 🚀 #Learning #WebDevelopment #JavaScript #HTML #CSS #DeveloperJourney Git-Link: https://lnkd.in/gNDfHb6h
