🚀 𝐃𝐚𝐲 𝟐/𝟏𝟓 𝐨𝐟 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠 𝐒𝐞𝐫𝐢𝐞𝐬 Today I learned about Data Types in JavaScript 💡 👉 Data types define what kind of data we are storing in a variable. 📌 In JavaScript, there are mainly 2 types: 1️⃣ Primitive Data Types String → "Hello" Number → 25 Boolean → true / false Null → empty value Undefined → value not assigned 2️⃣ Non-Primitive Data Types Object → { name: "Kanishka", age: 21 } Array → [1, 2, 3] 📌 Example: let name = "Kanishka"; // String let age = 21; // Number let isStudent = true; // Boolean 👉 JavaScript is a dynamically typed language, which means we don’t need to define the data type explicitly. Learning these basics is helping me build a strong foundation 💻✨ 💬 Question: Which data type do you use the most in JavaScript? Let’s learn together 🚀 #JavaScript #WebDevelopment #LearningInPublic #Day2 #FrontendDevelopment

Day 3 of My JavaScript Journey Today, I learned about JavaScript data types and how to define variables. JavaScript has two main types of data: Primitive data types: These include 7 types such as number, string, boolean, null, undefined, symbol, and bigint. Object: used to store more complex data. I also learned three ways to declare variables in JavaScript: • let • const • var One key thing I understood: "const" should be used by default, "let" when the value needs to change, and "var" is mostly outdated. Example: const name = "John"; let age = 20; Key takeaway: Understanding data types and variable declarations is fundamental to writing clean and predictable JavaScript code. #JavaScript #WebDevelopment #LearningInPublic #100DaysOfCode

Sharing a fresh perspective. Maps and Sets in JavaScript: A Deep Dive JavaScript provides several ways to store and manage data, with objects and arrays being the most commonly used structures. However, when dealing with unique values or key-value pairs with better efficiency, Maps and Sets come to the rescue! Read → https://lnkd.in/dvP2-4nH #CodingJourney #DevelopersLife #TechSkills #Blog
