️ Architecture: How to Visualize System Interaction — Use Case Diagram

Use case diagrams are an effective way to visualize system interactions and relationships between actors and use cases.
In a use case diagram, actors participate in specific actions, while relationships between use cases can be shown using 'include,' 'extend,' and inheritance.
For example, in the context of a restaurant system, a customer placing an order would trigger the restaurant to always receive the order, demonstrating the include relationship.
The extend relationship, on the other hand, suggests that delivering an order may be an optional part of the tracking process.
Tools like PlantUML can be used to create visual representations of these interactions for better understanding.

Understanding Recursion: A Programmer’s Superpower

Recursion is an essential concept in computer science, used for solving algorithmic puzzles and implementing complex data structures like trees and graphs.
Recursion involves a function calling itself to solve a problem, with examples like calculating factorials or Fibonacci sequences.
Factorials in recursion involve the function repeatedly calling itself with decreasing values until reaching a base case, with intermediate results stored on a call stack.
To improve recursion efficiency, memoization (storing results) can be used to prevent redundant calculations.
Recursion is compared to iteration in terms of style, performance, and readability, with recursion being more elegant but potentially slower due to stack usage.
Recursion is suitable for divide-and-conquer problems, tree and graph traversals, and mathematical computations like factorials and greatest common divisors.
However, recursion may not be suitable for cases with large recursion depths, performance-critical loops, or simpler iterations.
In C++, recursion is a powerful and elegant tool for solving complex problems by breaking them down into smaller sub-problems.
Recursion can simplify repetitive patterns in code, making it a superpower for programmers.
Recursion in C++ includes real-world examples, visualization of how it works, and tips for mastering it.

Mastering the DOM: My Journey Building an Interactive Dashboard with Vanilla JavaScript

Building an interactive dashboard with vanilla JavaScript offers a refreshing and educational experience in a world dominated by frameworks like React, Vue, and Angular.
The developer created a fully functional dashboard using only HTML, CSS, and JavaScript without relying on any frameworks.
The initial step involved defining a clean HTML layout with a sidebar for navigation and a main content section for dynamic cards and charts.
Each button in the sidebar was designed to control the content rendered without the need for a single-page app framework.
The application state was stored using localStorage and managed in a modular and organized manner.
Data-driven UI elements were implemented using native fetch calls and DOM manipulation, providing users with sortable visual reports through raw JavaScript logic.
The dashboard had minimal styling, giving it a polished look without utilizing frameworks like Bootstrap or Tailwind.
The deployed dashboard remained functional even after page reloads, showcasing the robustness of the vanilla JavaScript approach.
Enabling GitHub Pages on the repository allowed for easy deployment of the dashboard as a live app.
Building a feature-rich dashboard solely with vanilla JavaScript is not only feasible but also brings a sense of satisfaction.
The foundation created in this project makes it straightforward to integrate with real backends like Node.js + Express or Django REST, or extend functionalities using chart libraries such as Chart.js or ApexCharts.
