"forEach() vs for loop: Memory Usage in JavaScript"

Today is Day 10, and I explored some of the most important function-related concepts in JavaScript: ✅ Pure Functions ✅ First-Class & Higher-Order Functions ✅ map(), filter(), and reduce() ✅ Argument Object & Rest Parameter ✅ Variable Scope (Global, Local, Block) ✅ Scope & Scope Chain ✅ Recursion & Closures #Day10 #JavaScript #FrontendDevelopment #100DaysOfCode #LearningInPublic

Hidden JavaScript Trick You Should Know! Ever struggled with nested arrays? Here’s a simple method to flatten them instantly 👇 Check the image below — one line of code and your messy array becomes clean and readable. 💡 Tip: flat() can take a depth level as an argument. Try array.flat(Infinity) to flatten all levels! What’s your favorite “hidden” JavaScript method?

🧠 Small Practice for Logic Building 💻 Practicing a simple JavaScript function to count words from a sentence using arrow function and split() method. ✨ Every small logic builds a strong foundation for big projects! #JavaScript #LogicBuilding #CodingPractice #WebDevelopment #LearningEveryday

Today I Learned: JavaScript Functions in Depth Functions are the backbone of JavaScript they make our code reusable, organized, and powerful. Here’s what I learned today 👇 ✅ What functions are and why we use them ✅ Parameters & arguments ✅ Default and rest parameters ✅ Destructured parameters ✅ Nested functions & scope chain ✅ Arrow functions ✅ IIFE (Immediately Invoked Function Expressions) Every concept makes me realize how flexible and deep JavaScript really is. #JavaScript #WebDevelopment #100DaysOfCode #FrontendDevelopment #LearningInPublic

Hoisting is JavaScript’s way of moving declarations (not initializations) to the top of their scope before execution. 🧩💡 Tip: Always declare before use — hoisting can surprise you! #JavaScript #WebDev #FrontendTips #StructuredClone #JSDeepCopy #CodingTips #WebDevelopment Examples:

💻 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

JavaScript for 15 Days – Day 5: Functions Today, You will learn about Functions, one of the most important concepts in JavaScript. A function is basically a reusable block of code that performs a specific task. It helps you write cleaner, more organized, and less repetitive code. Example: function greet(name) { return `Hello, ${name}!`; } console.log(greet("Moussa")); // Hello, Moussa! Why functions matter: - They make your code reusable and modular. - They improve readability. - They help you manage logic step by step. JavaScript also supports arrow functions and function expressions, which you’ll explore in slides! #JavaScript #FrontendDevelopment #CodingJourney #LearnToCode #WebDevelopment #15DaysJS #DevPerDay

𝗘𝘃𝗲𝗿 𝗵𝗮𝗱 𝘆𝗼𝘂𝗿 𝗰𝗼𝗱𝗲 𝗮𝗰𝘁 𝘀𝘁𝗿𝗮𝗻𝗴𝗲 𝗮𝗻𝗱 𝘆𝗼𝘂 𝗰𝗼𝘂𝗹𝗱𝗻’𝘁 𝘁𝗲𝗹𝗹 𝘄𝗵𝘆? 😅 It happens a lot in JavaScript, especially when working with something called 𝗍𝗋𝗎𝗍𝗁𝗒 𝖺𝗇𝖽 𝖿𝖺𝗅𝗌𝗒 𝗏𝖺𝗅𝗎𝖾𝗌. In simple terms, JavaScript treats some things as true and others as false even if they don’t literally say “true” or “false.” I made a short snippet to show what I mean 👇 ✅ Lesson: Always check what’s really true or false before assuming. You can test it in the console using 𝗕𝗼𝗼𝗹𝗲𝗮𝗻(𝘃𝗮𝗹𝘂𝗲) to see if something is true or false. It’s a small thing but it can save hours of debugging. 👉 Learning by solving. 💻 #KabikaLearnsJS #JavaScript #WebDevelopment #CodingJourney #FrontendDevelopment 

Another small JavaScript project an Interactive Menu Filter! It includes buttons like All, Breakfast, Lunch, and Steak clicking on each filters the menu cards to show only related items. A great exercise for improving event handling and array filtering with JavaScript. #JavaScript #FrontendDevelopment #WebProjects #CodingPractice #LearnByDoing

Leveling Up in JavaScript Today I explored some powerful JS concepts: Destructuring – unpack values from arrays or objects easily. Spread syntax – clone or merge arrays/objects efficiently. Hoisting – JS moves declarations to the top before execution. IIFE (Immediately Invoked Function Expression) – a function that runs right after it’s defined. These small concepts build the foundation for cleaner, smarter code. What’s your favorite JavaScript concept? #JavaScript #WebDevelopment #LearningInPublic
