JavaScript Objects: Grouping Data with Structure

🚀 Just published a new blog on Understanding Objects in JavaScript. In this article, I explain what objects are, why they are important in JavaScript, and how they store data using key–value pairs. I also covered creating objects, accessing properties using dot and bracket notation, updating values, adding or deleting properties, and looping through object keys. 📖 Read the full article here: https://lnkd.in/gbxx6N2G Inspired by the amazing teaching of Hitesh Choudhary Sir and Piyush Garg Sir from Chai Aur Code. ☕💻 #javascript #webdevelopment #learninginpublic #chaiAurCode

🚀 Just published a new blog on JavaScript Arrays 101: Storing Multiple Values Easily. In this article, I explain the basics of arrays in JavaScript—what arrays are, why we use them, and how they help store multiple values in a single variable. I also covered creating arrays, accessing elements using index, updating values, using the length property, and looping through arrays with simple examples. 📖 Read the full article here: https://lnkd.in/gEvcCHGv Inspired by the amazing teaching of Hitesh Choudhary Sir and Piyush Garg Sir from Chai Aur Code. ☕💻 #javascript #webdevelopment #learninginpublic #chaiAurCode

Just published a new blog on JavaScript Execution Context, Hoisting, TDZ, and Call Stack. While learning these concepts, I realized how important it is to understand how JavaScript actually executes code behind the scenes. It helps explain a lot of behaviors that otherwise feel confusing. In this blog, I’ve tried to break down these concepts simply and clearly.

🚀 JavaScript Concepts Series – Day 4 / 30 📌 Scope in JavaScript 👀 Let's Revise the Basics 🧐 Understanding Scope in JavaScript is essential because it determines where variables are accessible in your code. Scope controls the visibility and lifetime of variables. 🔹 Global Scope Variables declared outside any function or block. Accessible anywhere in the program. 🔹 Function Scope Variables declared inside a function. Accessible only within that function. Commonly created using var. 🔹 Block Scope Variables declared inside { } like loops or if statements. Accessible only inside that block. Created using let and const. 💡 Key Insight Global Scope → Accessible everywhere Function Scope → Accessible only inside the function Block Scope → Accessible only inside the block {} Understanding scope helps you avoid variable conflicts, write cleaner code, and debug issues faster. More JavaScript concepts coming soon. 🚀

🚀 Just Published: Blog 5 of Javascript blog series Understanding Functions in JavaScript (Beginner Friendly) Functions are one of the most important building blocks in JavaScript—but many beginners struggle with: 👉 Function Declaration vs Function Expression 👉 When to use which 👉 Why some functions work before defining (hoisting) So I wrote a simple, practical guide to understand JS functions.

🚀 Day 32 of My JavaScript Journey Today was all about diving deeper into Advanced JavaScript concepts 💡 Here’s what I explored: 🔹 Functions in ES5 Function Statement Function Expression Anonymous Function 🔹 Functions in ES6 Arrow Functions (Fat Arrow) Arrow Functions with Implicit Return Arrow Functions with Implicit Return with Single Parameter 🔹 Higher Order Functions (HOF) Understanding how functions can accept other functions as arguments or return them — super powerful concept! 🔹 Closures One of the most important JS concepts — functions remembering their lexical scope even when executed outside. 🤯 🔹 Destructuring Object Destructuring Array Destructuring Cleaner and more readable way to extract values. 🔹 Spread Operator (...) Used it to clone arrays and objects (reference data types) easily. 🔹 Deep Cloning Learned different ways to deeply copy objects: JSON.parse(JSON.stringify(obj)) structuredClone(obj) 💻 Code Snippets: // ES5 Function function greet(name) { return "Hello " + name; } // ES6 Arrow Function const greetUser = (name) => { return `Hello ${name}`; // Implicit Return const add = (a, b) => a + b; // Single Parameter const square = num => num * num; // Higher Order Function function operate(a, b, fn) { return fn(a, b); } // Closure Example function outer() { let count = 0; return function inner() { count++; return count; } } // Destructuring const user = { name: "John", age: 25 }; const { name, age } = user; // Spread Operator const arr = [1, 2, 3]; const newArr = [...arr]; // Deep Cloning const obj = { a: 1, b: { c: 2 } }; const deepClone1 = JSON.parse(JSON.stringify(obj)); const deepClone2 = structuredClone(obj); Every day, JavaScript keeps getting more interesting! 🔥 Consistency is the key — see you on Day 33 💪 #JavaScript #WebDevelopment #CodingJourney #LearnToCode #SheryiansCodingSchool #AdvancedJavaScriptConcepts

🚀 Day-22 — Revisiting JavaScript Basics Today I went back to JavaScript fundamentals and revised some important concepts. I focused on: • Throttling — limits how often a function runs Example: window.addEventListener("scroll", throttle(handleScroll, 2000)) • Debouncing — runs a function only after a delay (when user stops action) Example: input.addEventListener("input", debounce(handleSearch, 500)) • Promises — handle async operations with success/failure Example: fetch(url).then(res => res.json()).then(data => console.log(data)) • Asynchronous JavaScript — allows non-blocking execution Example: async function getData(){ const res = await fetch(url) const data = await res.json() } Revisiting these basics helped me understand them more clearly and how they actually work in real projects. Going back to fundamentals always helps. Ankur Prajapati Satwik Raj #JavaScript #WebDevelopment #LearningInPublic #BuildInPublic#21daysofcoding#sheriyans

🚀 Day 8 — Mastering JavaScript Arrays & Higher Order Functions Continuing my journey of strengthening core JavaScript fundamentals, today I focused on one of the most practical and frequently used concepts — Arrays & Higher Order Functions 👇 Arrays may look simple at first, but when combined with higher order functions like "map", "filter", and "reduce", they become extremely powerful for solving real-world problems. 🔹 Covered topics: - What are Arrays & why we use them - Indexing & accessing elements - Adding & removing elements ("push", "unshift", "splice") - Difference between "slice" & "splice" - Common methods ("indexOf", "includes", "sort") - Higher Order Functions (🔥 important) - "forEach()" vs "map()" - "filter()" for conditional data - "reduce()" for complex logic (🔥 most important) - "find()" & "findIndex()" - Method chaining (real-world usage 💡) 💡 Key Learning: Higher Order Functions make code clean, readable, and scalable. Instead of writing long loops, we can write powerful one-line logic. 👉 Always remember: - "map()" → transforms data - "filter()" → selects data - "reduce()" → converts data into a single value Understanding these concepts is crucial for React, real-world projects, and technical interviews. 📌 Day 8 of consistent preparation — getting stronger with JavaScript fundamentals 🔥 #JavaScript #WebDevelopment #FullStackDeveloper #CodingJourney #MERNStack #InterviewPreparation #Frontend #Backend #LearnInPublic #Developers #Consistency #100DaysOfCode #LinkedIn #Connections

🚀 Just published a new blog on JavaScript Operators: The Basics You Need to Know. In this article, I explain the fundamentals of JavaScript operators, including arithmetic operators, comparison operators, logical operators, and assignment operators with simple examples. I also showed the difference between == and === to help beginners understand how comparisons work in JavaScript. 📖 Read the full article here: https://lnkd.in/gT5xbcix Inspired by the amazing teaching of Hitesh Choudhary Sir and Piyush Garg Sir from Chai Aur Code. ☕💻 #javascript #webdevelopment #learninginpublic #chaiAurCode

New post on arrow functions in JavaScript, covering the basics with simple examples. Arrow functions are essentially a shorter way to write function expressions using the => syntax, introduced in ES6.
