JavaScript Scope & Object Methods Explained

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.

Day-87 📘 Python Full Stack Journey – JavaScript Practice & Math Functions Today’s learning was very hands-on, focusing on JavaScript interactivity, validation, and built-in utilities. 🎯 What I worked on today: 🎨 Interactive Program Wrote a program to change the color of an SVG on click, toggling between red ↔ black continuously using event handling. 🧪 User Input & Validation Received user input using: Copy code Js document.getElementById('ab').value Applied conditions such as: isNaN() Value checks (< 10, etc.) Displayed validation results dynamically inside an HTML tag. Implemented form validation using alert() for user feedback. 🧮 JavaScript Math Module Explored several useful Math methods: pow() floor() ceil() sign() round() max() / min() sqrt() PI sin() / cos() / tan() trunc() random() These exercises really helped connect logic, user interaction, and calculations in real-world scenarios. JavaScript is getting more powerful and fun every day! 🚀 #JavaScript #PythonFullStack #WebDevelopment #Frontend #CodingJourney #LearningToCode #Upskilling #TechSkills #ContinuousLearning

Today I learned about static files in Django. In a Django project, the static folder is used to store files like CSS, JavaScript, and images that help with the design and functionality of the website. To use static files, we need to configure them in the settings.py file: STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static') ] After setting this up, we can easily load CSS, JS, and images in our templates. Slowly building my understanding of Django step by step. #Django #Python #WebDevelopment #Fullstackdeveloper

Is JavaScript really an interpreted language? JavaScript is often described as an interpreted language but modern JS engines like V8 actually compile before executing it. To answer this question, I created blog that explains the following:  1) What is Compiler, interpreter and JIT Compiler 2) Understanding the behavior of JavaScript 3) Background of JS Engine 4) How JS engine utilize JIT Compilation Read here 👇 https://lnkd.in/dj4ecJA4 #javascript #webdev #softwareengineering #programming

🚀 New Blog Posted... Hello Developers 🖐, We often start learning JavaScript by writing code, but many struggle to truly understand what happens behind the scenes. So I wrote a beginner-friendly article explaining the core building blocks of JavaScript: • Variables • Data Types • Scoping • var, let, and const In this article, I break down these concepts in the simplest way possible with visual explanations and practical examples so beginners can understand how JavaScript actually works under the hood. If you're starting your JavaScript journey or revising fundamentals, this will help. 🗒️Read the full article here 👇 : https://lnkd.in/ge26UnkM Feedback from fellow developers is always welcome.

JavaScript is the standard language for web application frontends, but does that mean your API layer should also use JavaScript? Not necessarily. In this blog, #KeyholeTeam’s Chris B. compares two lightweight API frameworks—Express.js (JavaScript) and FastAPI (Python)—to explore how each handles modern API development using a simple Songs API example. 🎵 By building the same Songs API in both frameworks, Chris examines key differences in routing, request validation, error handling, and project setup. He also looks at broader considerations like ecosystem tooling (NPM vs. PyPI), runtime performance, and developer experience. While Express benefits from the maturity and breadth of the Node.js ecosystem, FastAPI leverages Python’s strong typing and powerful backend tooling. Ultimately, the right framework depends on your team’s skills, the surrounding tech stack, and the types of workloads your application needs to support. Read the full comparison to learn how these frameworks stack up when designing your API layer. → https://lnkd.in/gTeDcW5G #APIDevelopment #JavaScript #Python #Nodejs #Expressjs

It seems there’s value in trying to understand previously written code and make it more efficient. (Especially utilizing #JavaScript in #ReactJS to break up repetitive code and use logic to handle the components. But sometimes it seems easier to start from scratch, and try to understand the code that way, by completely rewriting it, forcing oneself to think through it again, perhaps in a new way (multiple ways to do same thing). I wonder which approach is better for deeply learning/practicing a programming language, and also which is more common in a typical professional industry (probably the former, but new applications have to be built too — unless they’re always built on top of existing codebases). More updates on these processes to come while continuing to document the journey with JavaScript, #Python, and other languages/technologies such as #Jest, different APIs, and performing CRUD operations for #fullStack projects.
