Is there a Caesar cipher example on JSFiddle?

Yes, there are numerous examples of Caesar cipher implementations available on JSFiddle. JSFiddle is a popular online code editor that allows users to create, share, and test HTML, CSS, and JavaScript code snippets. You can find various Caesar cipher examples there, ranging from basic implementations to more advanced versions with user interfaces.

To find a Caesar cipher example on JSFiddle, you can follow these steps:

1. Go to JSFiddle: Open your web browser and navigate to the JSFiddle website (jsfiddle.net).

2. Use the Search Function: JSFiddle has a search bar where you can enter keywords to find relevant code snippets. Type "Caesar cipher" or "Caesar cipher JavaScript" into the search bar and press Enter.

3. Browse the Results: You will see a list of JSFiddle examples related to the Caesar cipher. Click on the links to view the code and the output.

4. Analyze the Code: Once you open a JSFiddle, you will see three panels: HTML, CSS, and JavaScript. The JavaScript panel will contain the Caesar cipher implementation. You can examine the code to understand how it works.

5. Test the Code: You can modify the code in the JavaScript panel and see the results in the output panel. This allows you to experiment with different inputs and understand the cipher better.

Here's a basic example of a Caesar cipher implementation in JavaScript that you might find on JSFiddle:

function caesarCipher(str, shift) {
  let result = '';
  for (let i = 0; i < str.length; i++) {
    let char = str[i];
    if (char.match(/[a-z]/i)) {
      let code = str.charCodeAt(i);
      if (code >= 65 && code <= 90) {
        char = String.fromCharCode(((code - 65 + shift) % 26) + 65);
      } else if (code >= 97 && code <= 122) {
        char = String.fromCharCode(((code - 97 + shift) % 26) + 97);
      }
    }
    result += char;
  }
  return result;
}

// Example usage:
let encrypted = caesarCipher("Hello, World!", 3);
console.log("Encrypted:", encrypted); // Output: "Khoor, Zruog!"

let decrypted = caesarCipher(encrypted, -3);
console.log("Decrypted:", decrypted); // Output: "Hello, World!"

This JavaScript code defines a function caesarCipher that takes a string and a shift value as input and returns the encrypted or decrypted string. You can copy this code into the JavaScript panel of JSFiddle and test it.

By exploring JSFiddle, you can find various implementations of the Caesar cipher, each with its own approach and features. This is a great way to learn about cryptography and JavaScript programming.
