Mastering JavaScript Fundamentals with Var, Let, Const

Just published a new blog on JavaScript Arrays 🚀 Arrays are one of the most commonly used data structures in JavaScript, but understanding how they actually work makes writing cleaner and more efficient code. In this post I covered: • How arrays are created in JavaScript • How they store and manage data • Basic operations developers use every day This article is part of my effort to revisit JavaScript fundamentals and document the learning along the way. If you're learning JavaScript or refreshing your basics, this might be helpful. #javascript #webdevelopment #programming #frontend #developers url - https://lnkd.in/d7kAfXpf Chai Aur Code Akash Kadlag Barun Tiwary @jay Hitesh Choudhary Piyush Garg

Day 9 – JavaScript Data Types & Operators We’re continuing our 30 Days Web Development Learning Series with JavaScript Data Types and Operators. Today, we dive deeper into how JavaScript handles different types of data like strings, numbers, booleans, null, and undefined. You’ll also learn how to use arithmetic, comparison, and logical operators to perform calculations and make decisions in your code. Understanding data types and operators is essential for writing logical and efficient JavaScript programs. #WebDevelopment #JavaScript #JSBasics #FrontendDevelopment #CodingSeries #TryunitySolutions

Day 3 of Learning JavaScript 🚀 Today I learned about JavaScript data types. Common ones include: • String • Number • Boolean • Undefined • Null Example: let name = "Alex" let age = 25 let isStudent = true Understanding data types helps write more reliable code. #javascript #frontenddeveloper

Many developers jump to frameworks… but ignore JavaScript fundamentals. It works — until things break. Then come the real issues: Confusion in logic. Debugging struggles. Weak problem-solving. Framework dependency. JavaScript in 2026 isn’t just syntax. It’s about mastering the core concepts. 💡 Must-Know Basics: • Variables & clean declarations • Data types & operators • Functions & logic building • Loops & arrays • DOM manipulation ⚡ Strong JavaScript basics = Strong developer foundation #JavaScript #WebDevelopment #FrontendDevelopment #CodingTips #LearnJavaScript #DeveloperLife #ProgrammingBasics #SoftwareEngineering

Day 13 of Learning JavaScript 💻 Today I practiced accessing and modifying object properties. Example: user.name = "New Name" This is useful when working with dynamic data. Feels good to understand how real apps update data. #javascript #frontenddeveloper

When working with data in JavaScript, arrays are everywhere. But storing values is only half the job. Most of the time we need to process that data. For example: Transform values Remove unwanted items Calculate totals JavaScript provides powerful built-in methods that make this much easier: map() → transform each value in an array filter() → select values that match a condition reduce() → combine values into a single result In my latest blog, I explain these methods using simple examples and show how they compare with traditional loops. https://lnkd.in/dQsy3i78 If you're learning JavaScript fundamentals, these are methods you’ll use almost every day. #javascript #webdevelopment #coding #learninpublic #chaicode

cohort 2.0 JavaScript an array is more than just a list of values. Itss a way to organize information,process data and solve problems efficiently. ex : - let task = ["javascript", "practice coding"]; Add data → push() Remove data → pop() Transform data → map() Filter data → filter() these simple tools allow developers to manipulate data in powerful ways the more i learn code, the more i realize that mastering basic concepts like arrays makes complex problems much easier to solve #JavaScript #CodingJourney #WebDevelopment #learnToCode #CareerGrowth

💡 JavaScript Array Methods Every Developer Should Know. Arrays are one of the most used data structures in JavaScript. Mastering array methods can make your code cleaner and more powerful. Important methods every developer should know: ✔️ map() – Transform each element ✔️ filter() – Select elements based on conditions ✔️ reduce() – Convert array to single value ✔️ find() – Get first matching element ✔️ some() / every() – Condition checks. Learning these methods improves problem solving and coding efficiency. #JavaScript #WebDevelopment #FrontendDeveloper #Coding

🚀 Day 933 of #1000DaysOfCode ✨ Sorting Arrays in JavaScript — Different Types Explained Sorting isn’t always just about numbers in ascending order. In today’s post, I’ve covered sorting arrays in JavaScript for different data types — whether it’s numbers, strings, objects, or more complex structures. The goal is to help you understand how sorting behaves internally and how to customize it properly. If you’ve ever faced unexpected results while using `.sort()`, this post will help you gain clarity and control. 👇 What type of array do you find most challenging to sort? #Day933 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity
