Underrated step for logic building in programming.

Logic building is a crucial and complex skill in programming. In essence, it is ability to come-up with solution of coding problem and write precise instructions ( or code) that a computer can execute autonomously. This skill requires aligning your thought process with computer and its capabilities. And running through code some-what abstractly to know and predict the behavior of code before it is executed. To be able to do this, one essential step that many beginner programmers overlook is performing dry runs. Understanding Dry Runs The concept of a dry run in programming is straightforward: can you mentally execute your code and predict its output without actually running it on a computer? While this seems simple, it is a challenging task. Typically, we are taught to write code, run it, and observe the output. This cycle is essential because code needs to run to be validated. However, if you rely solely on running your code to understand its behavior, you may struggle with building

23.1.1 Energy & Mass Equivalence

Energy & Mass Equivalence

  • Einstein showed in his theory of relativity that matter can be considered a form of energy and hence, he proposed:
    • Mass can be converted into energy
    • Energy can be converted into mass
  • This is known as mass-energy equivalence, and can be summarised by the equation:

E = mc^2

  • Where:
    • E = energy (J)
    • m = mass (kg)
    • c = the speed of light (m s-1)
  • Some examples of mass-energy equivalence are:
    • The fusion of hydrogen into helium in the centre of the sun
    • The fission of uranium in nuclear power plants
    • Nuclear weapons
    • High-energy particle collisions in particle accelerators

  Hi guys, in this blog we will be build JavaScript array methods as a function from JavaScript basics as it is great and simple way to refine your JavaScript programming skill and make your fundamentals strong as beginner and you’ll also know various JavaScript array methods along the way, we will start from easiest to more complex ones, i have try to keep it as beginner friendly as possible.  First, i will be introducing the array method with their example input and output, then we will examine those methods, identifying which programming tools and tricks to used and in which order to arrange them. Along that process we will build pseudocode algorithm for required function and later on, i will show you flowchart version of that algorithm, the important tip that i can give to you all, to get most out of this blog, is to first try to build it by yourself then come to this blog. 1. Array.isArray() :  So lets, start with simple one Array.isArray() method. The Array.isArray() method

Simplified working mechanism of project In this tutorial, we're going to delve into a fascinating React project. Our goal? To construct an Eisenhower matrix, an incredibly effective productivity tool designed to help prioritize tasks based on their urgency and importance. This project facilitate user to enter todo with category based on its importance and urgency. Source code link About the Project Our React project has been designed around two main components, AddTodo and DisplayMatrix . The AddTodo component is designed to capture the user's input. It includes a function that transfers user data to the database, ensuring that all tasks are stored and can be accessed when needed. On the other hand, DisplayMatrix provides a visual representation of the to-do list. To ensure that tasks can be easily managed, each item is accompanied by a delete button for easy removal when tasks are completed or need to be discarded.  Under DisplayMatrix there are two nested components To

Above image shows the working mechanism this project  Source code:  Source code link      Welcome to this comprehensive tutorial where we'll explore the step-by-step process of building a dynamic search bar in React. Throughout this guide, we will delve into implementing conditional show/hide functionalities and enabling filtering capabilities within the search bar. To kick things off, let's initiate your project using 'npm create vite@latest'. Additionally, we'll be leveraging the 'react-icons' package to enhance the search bar's visual elements; installation is as simple as running 'npm i react-icons'. Let's break down the project into two key sections: 1. Show and Hide Functionality of the Search Bar 2. Rendering Match Results Based on the Search Input Section 1: Show and Hide Functionality: - Create SearchBar component with input field and close icon. Import it to App.jsx. -  Initialize useState  to track input in search's input field
