Day-74 📘 Python Full Stack Journey – JavaScript Basics Today I took my first step into JavaScript, the language that brings interactivity to websites. 🚀 🎯 What I learned today: ⚙️ Introduction to JavaScript JavaScript is a programming language used to create interactive websites It can hide/show elements, perform form validation, and create animations 🔗 Connecting JavaScript with HTML Internal JavaScript using the <script> tag Can be placed inside the <head> (below the <title> tag) or at the end of the <body> Best practice: place scripts at the end of the body so HTML loads first External JavaScript Create a .js file and link it using the <script> tag at the end of the body 🖨️ Output in JavaScript document.writeln() — used to print output on the webpage 🧠 Variables in JavaScript var — globally scoped, allows re-declaration and re-assignment let — block scoped, re-assignment allowed, re-declaration not allowed const — block scoped, neither re-assignment nor re-declaration allowed 🔢 Primitive Data Types Number String Boolean Undefined Null BigInt Symbol (each symbol is unique, even with the same description) Learning JavaScript fundamentals made it clear how logic, interaction, and UI come together on the web. Excited to go deeper into scripting and dynamic web behavior! 💻✨ #JavaScript #PythonFullStack #WebDevelopment #Frontend #LearningJourney #CodingJourney #Upskilling #TechSkills #ContinuousLearning

Day-85 📘 Python Full Stack Journey – JavaScript DOM Manipulation Today I went deeper into the DOM (Document Object Model) and learned how JavaScript can dynamically access and update HTML elements on a webpage. 🎯 What I learned today: 🌐 getElementsByClassName() Accesses elements by class name Requires index to target a specific element Used = to replace content and += to append content Applied the same data to multiple elements using a for loop 🌐 getElementsByTagName() Accesses elements by tag name Requires index for element selection Used replace (=) and append (+=) operations 🎯 querySelector() Targets the first matching element Accepts: Element selector ('p') Class selector ('.demo') ID selector ('#demo') 🎯 querySelectorAll() Targets all matching elements Accessed elements using index Supports element, class, and ID selectors Learning DOM manipulation really highlighted how JavaScript brings interactivity and dynamic behavior to web pages. Every step makes frontend development more exciting! 🚀 #JavaScript #PythonFullStack #WebDevelopment #Frontend #DOM #CodingJourney #LearningToCode #Upskilling #TechSkills #ContinuousLearning

📘 Day 62: JavaScript Basics & Variables 🔹 JavaScript Introduction • JavaScript is a programming language used to make webpages interactive • Helps in animations, hiding/showing elements, and form validation • Mainly used in front-end development 🔹 Linking JavaScript with HTML 💡 Internal Linking • Can be added inside <head> or at the end of <body> • End of <body> is preferred to avoid loading delays 💡 External Linking • Create a .js file and link it using <script src="file.js"></script> 🔹 Variable Declarations • var, let, and const are used to declare variables ✅ var • Globally scoped • Allows recreation and reassignment ✅ let • Block scoped • No recreation allowed • Reassignment allowed ✅ const • Block scoped • No recreation or reassignment 🔹 Primitive Data Types in JavaScript • Number • String • Boolean • Undefined • Null • BigInt • Symbol 💡 Key Notes • JS treats integers and decimals both as Number • Strings are text inside quotes • Boolean → true/false • Undefined → variable declared but no value • Null → intentionally empty value • BigInt → large numbers ending with n • Symbol → unique and private values 🚀 Building strong JavaScript fundamentals step by step! #Day62 #JavaScript #WebDevelopment #FrontendDevelopment #CodingJourney #LearnJS #ProgrammingBasics #WebDevJourney #TechSkills

Day-80 📘 Python Full Stack Journey – JavaScript Logic & Conditions Today I focused on decision-making and logic in JavaScript — essential concepts for building interactive and dynamic applications. 🎯 What I learned today: 🔍 Comparison Operators ==, === !=, !== >, <, >=, <= Understanding the difference between loose and strict comparison was especially important. 🔗 Logical Operators && (AND) || (OR) ! (NOT) Used for combining and controlling conditions. ❓ Conditional (Ternary) Operator A concise way to write simple if-else conditions. 🧭 Conditional Statements Making decisions in code using if, else if, and else. 🧑💻 User Interaction prompt() — taking input from the user alert() — displaying messages to the user These concepts showed me how JavaScript brings logic and interactivity together on the web. Excited to keep building smarter, user-driven applications! 🚀 #JavaScript #PythonFullStack #WebDevelopment #Frontend #CodingJourney #LearningToCode #Upskilling #TechSkills #ContinuousLearning

𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 𝗜𝗻𝗵𝗲𝗿𝗶𝘁𝗮𝗻𝗰𝗲: 𝗜𝘁’𝘀 𝗢𝗯𝗷𝗲𝗰𝘁𝘀 𝗔𝗹𝗹 𝗧𝗵𝗲 𝗪𝗮𝘆 𝗗𝗼𝘄𝗻 🧬 Hi everyone! I’ve just published Part 6 of my JavaScript deep-dive series: 𝗧𝗵𝗲 𝗣𝗼𝘄𝗲𝗿 𝗼𝗳 𝗣𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗲𝘀. Most developers use class and extends every day, but few realize that JavaScript doesn't actually have "classes" in the traditional sense. It has something more flexible: 𝗣𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗮𝗹 𝗜𝗻𝗵𝗲𝗿𝗶𝘁𝗮𝗻𝗰𝗲. If you've ever been confused by .prototype vs [[Prototype]], or wondered why [].toString() behaves differently than {}.toString(), this article breaks down the "Family Tree" of the JavaScript engine. 𝗜𝗻 𝘁𝗵𝗶𝘀 𝗽𝗮𝗿𝘁, 𝘄𝗲 𝗲𝘅𝗽𝗹𝗼𝗿𝗲: • 𝗧𝗵𝗲 𝗣𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗲 𝗖𝗵𝗮𝗶𝗻: How the engine performs a "search party" across objects to find methods. • 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻.𝗽𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗲: The meta-layer where even the Object constructor is a student of the Function constructor. • 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝘄𝗶𝘁𝗵 𝗡𝘂𝗹𝗹: Why Object.create(null) is the ultimate protection against "Prototype Pollution." • 𝗧𝗵𝗲 𝗖𝗹𝗮𝘀𝘀 𝗜𝗹𝗹𝘂𝘀𝗶𝗼𝗻: Why ES6 classes are actually just "syntactic sugar" over the internal slots we’ve been studying. Master the chain, and you master the very foundation of how JavaScript manages memory and behavior. Read the full deep-dive here: https://lnkd.in/dCzneRAE 🔗 𝗡𝗲𝘅𝘁 𝘂𝗽: We tackle the most misunderstood concept in the language, the this keyword. #𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 #𝗪𝗲𝗯𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 #𝗦𝗼𝗳𝘁𝘄𝗮𝗿𝗲𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 #𝗖𝗼𝗱𝗶𝗻𝗴 #𝗣𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗲𝘀 #𝗢𝗢𝗣 #𝗧𝗲𝗰𝗵𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 #𝗜𝗻𝘁𝗲𝗿𝗺𝗲𝗱𝗶𝗮𝘁𝗲𝗝𝗦 #𝗣𝗿𝗼𝗴𝗿𝗮𝗺𝗺𝗶𝗻𝗴
