Learn JavaScript basics with this interactive tutorial

🚀 Day 19 of JS series by Rohit Negi Today, I learned about one of the most important concepts in modern JavaScript — Promises! Here’s what I explored 👇 ✅ What a Promise is and how it’s created ✅ How to handle Promises using .then() and .catch() ✅ What JSON (JavaScript Object Notation) is. It is independent of programming languages ✅ How Promises help solve the callback hell problem #JavaScript #WebDevelopment #LearnInPublic #AsyncJS #Promises #CodingJourney

Day 8 of #30DaysOfJavaScript on LeetCode Today's challenge: 2629 — Function Composition The task was to implement a function that takes an array of functions [f1, f2, f3, ..., fn] and returns a new function that represents their composition. In simple terms, the composed function should apply all the given functions from right to left, just like: f(g(h(x))) Here’s my solution 👇 var compose = function(functions) { return function(x) { let res = x; for (let i = functions.length - 1; i >= 0; i--) { res = functions[i](res); } return res; } }; This challenge gave me a deeper understanding of how function chaining and composition work in JavaScript — building complex logic from smaller, reusable functions. It’s a beautiful example of how functional programming principles simplify problem-solving!

After playing around with map(), filter(), and reduce(), I wanted to go a bit deeper into how JavaScript handles function borrowing and context binding — so I decided to rebuild call(), apply(), and bind() 💪 Here’s how my mini versions turned out 👇 🧠 What I learned: How JavaScript functions can borrow context from other objects Why bind() returns a new function (instead of calling it immediately) How important it is to handle this carefully — one tiny mistake can break everything 😅 Building these gave me a much clearer understanding of how function context and execution work in JS 🔍 #javascript #ReactJs #nodeJs #interview-questions #programming

🚀 Callback Hell in JavaScript: The “Pyramid of Doom”! In JavaScript, Callback Hell happens when multiple asynchronous functions are nested inside each other, creating deeply indented code that’s hard to read, debug, and maintain. 😩 ✅ How to avoid it: Use Promises to flatten nested callbacks Use async/await for clean, readable code Modularize your logic into smaller functions #JavaScript #WebDevelopment #CallbackHell #AsyncAwait #Promises #CodingTips #FrontendDevelopment #WebDevelopers #CleanCode #Programming #LearnToCode #CodeSmarter #DeveloperCommunity

🚀 Learning JavaScript: Practicing “for loops”! Today, I worked on different examples using for loops in JavaScript — a powerful tool for repeating tasks efficiently. Here’s what I explored 👇 💡 Tasks I completed: 1️⃣ Printed even numbers from 2 to 20 2️⃣ Printed odd numbers from 1 to 19 3️⃣ Calculated the square of numbers from 1 to 5 4️⃣ Found the sum of numbers from 1 to 10 5️⃣ Calculated the product of numbers from 1 to 5 6️⃣ Printed the cube of numbers from 1 to 5 7️⃣ Displayed numbers from -5 to 5 🧠 This exercise helped me understand how iteration, increment, and logical conditions work together in JavaScript loops. 🌱 Every small project like this helps strengthen my programming logic and problem-solving skills! #JavaScript #CodingJourney #ForLoop #WebDevelopment #100DaysOfCode #FrontendDevelopment #LearnToCode

👋 Hello everyone! Today I'd practiced and solved ✅ coding questions on Javascript concepts DOM Manipulations, functions and loops. In this practice I design Your Ordered Items Page by using Javascript DOM Manipulations. Using For...of loop iterate over the list get the each item and append it to the page. Using Function Expression removed the each item from the page. Key Takeaways: ✅ Designing Your Ordered Items Page using Javascript ✅ DOM Manipulations using Javascript ✅ Handling User Interactions using functions ✅ Removed the items using removeChild() method #Day4 of #30Daysofcodingchallenge #Javascript #coding #programming #NxtWave #CCBP
