Here are some beginner project ideas for Python and JavaScript:

Python Projects:

• Build a calculator that can perform basic arithmetic operations such as addition, subtraction, multiplication, and division.
• Create a program that generates a random number and asks the user to guess the number. Give them hints such as "higher" or "lower" depending on the user's guess.
• Build a simple game using the Pygame library, such as a snake game or a Pong game.
• Write a program that scrapes data from a webpage using the Beautiful Soup library.
• Build a program that plays a song or a sound effect when a certain event happens, such as receiving a new email or a text message.

JavaScript Projects:

• Build a simple to-do list app that allows users to add and delete tasks.
• Create a program that changes the background color of the webpage using the DOM.
• Build a rock, paper, scissors game where the user plays against the computer.
• Write a program that displays a random quote or joke on the webpage using the Fetch API.
• Create a weather app that displays the current weather of a certain location using an API, such as OpenWeatherMap.

Here's a sample code in Java that creates a console-based calculator:

java
 
 
Copy code
import java.util.Scanner;

public class Calculator {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("Enter first number: ");
        int num1 = scanner.nextInt();

        System.out.println("Enter second number: ");
        int num2 = scanner.nextInt();

        System.out.println("Enter operator (+, -, *, /): ");
        char operator = scanner.next().charAt(0);

        int result;

        switch (operator) {
            case '+':
                result = num1 + num2;
                break;
            case '-':
                result = num1 - num2;
                break;
            case '*':
                result = num1 * num2;
                break;
            case '/':
                result = num1 / num2;
                break;
            default:
                System.out.println("Invalid operator.");
                return;
        }

        System.out.println(num1 + " " + operator + " " + num2 + " = " + result);
    }
}

The program prompts the user to enter two numbers and an operator (+, -, *, /). It then performs the corresponding arithmetic operation and displays the result on the console.

Note that this implementation assumes integer inputs, and does not handle input validation or error handling. Tracking multiple operations, history, or capability to handle decimals, exponentials and other operations would require more complex code.

Using JavaScript, you can create a calculator with chart as follows:

javascript
 
 
Copy code
function calculateCost(storage, transfer){
  //Add relevant code here
  let backblazeCost = 7 + (storage * 0.005) + (transfer * 0.01);
  let bunnyCost = 10 + (storage * 0.01) + (transfer * 0.01);
  //Depending on the type of storage, the price differs
  let scalewayCost = (storage <= 75 ? 0 : storage - 75) * 0.06 + (transfer <= 75 ? 0 : transfer - 75) * 0.02;
  let vultrCost = 5 + (storage * 0.01) + (transfer * 0.01);

  //Identify and color the cheapest option in the chart
  let priceRange = [backblazeCost, bunnyCost, scalewayCost, vultrCost];
  let minPrice = Math.min(...priceRange);
  let color = priceRange[0] === minPrice ? 'red' : 'default';

  //Return the minimum price colored
  return {price: minPrice, color: color};
}

Explanation: This JavaScript code defines a function called calculateCost which takes two parameters - storage and transfer - for the number of Storage and Transfer requested. It then calculates the cost for each service and identifies the minimum cost out of them. The corresponding color for the minimum cost is then set to red, and returned as an object with the computed cost and its color.

To determine which rule is overriding applied style, you need to find the “specificity” of the rules applied. The more “specific” of a rule is, the more likely to override another rule. CSS works by cascading a set of rules and the last rule that is set is what gets applied. To help determine the specificity of a rule, you can use a calculator such as Specificity Calculator to see which rule is more specific and overrides any style setting.

Yes, it is possible to code a calculator. Depending on the level of complexity, the programming language used can vary. For instance, a basic calculator can be made with HTML and JavaScript. Here's an example of a calculator written in JavaScript:

javascript
 
 
Copy code
// Create variables
let input1 = document.querySelector('#input1'); 
let input2 = document.querySelector('#input2'); 
let addButton = document.querySelector('#addButton');
let result = document.querySelector('#result');

// Button click calculation
addButton.addEventListener('click', () => {
    result.value = parseFloat(input1.value) + parseFloat(input2.value);
});
