JavaScript Multiplication Table Generator

This is a simple JavaScript program that generates a multiplication table for a given number up to 20.

How to Use

1. Run the JavaScript code in a web browser.
2. You will be prompted to enter a number.
3. The program will then display a multiplication table for the entered number up to 20.

Example

If you enter the number 5, the program will display:

• 5 * 1 = 5
• 5 * 2 = 10
• 5 * 3 = 15 ...
• 5 * 20 = 100

How it works

1. The prompt function is used to ask the user to enter a number. The message "Hello, I'm The Calculation Robot\nEnter a number you want to calculate:" is displayed to the user. The entered number is stored in the number constant.

const number = prompt(
  "Hello, I'm The Calculation Robot\nEnter a number you want to calculate:"
);

2. An empty string result is initialized to store the multiplication table.

let result = "";

3. A for loop is used to iterate from 1 to 20. In each iteration, the current number (factor) is multiplied with the user-entered number (number), and the result is appended to the result string along with the current multiplication operation.

for (let factor = 1; factor <= 20; factor++) {
  result += " -> " + number + " * " + factor + " = " + number * factor + "\n";
}

4. Finally, an alert is used to display the multiplication table. The message includes the user-entered number and the calculated results.

alert("The result of multiplying the number " + number + "\n\n" + result);

In summary, this code is a simple way to generate a multiplication table for a given number in JavaScript. It uses a for loop to iterate over a range of numbers, performs multiplication in each iteration, and stores the results in a string that is then displayed to the user
