How do I convert a string to a byte array in JavaScript?
Alex K

In JavaScript, you can convert a string to a byte array using various techniques. Here's a step-by-step guide on how to achieve this: 1. Get the string you want to convert:

1

   const str = 'Hello, World!';

Replace'Hello, World!' with the actual string you want to convert. 2. Create an empty array to store the byte values:

1
2
3

   const byteArray = [];

This empty array will hold the byte values of the string. 3. Iterate over the characters of the string: Use a loop, such as a for loop or a forEach loop, to iterate over each character in the string.

   for (let i = 0; i < str.length; i++) {
     const charCode = str.charCodeAt(i);
     byteArray.push(charCode);
   }

In this example, a for loop is used to iterate over each character of the string. ThecharCodeAt() method retrieves the Unicode value of the character at the current index (i), and it is pushed to thebyteArray. 4. Use the byte array: Once the conversion is complete, you can use thebyteArray for further processing or manipulation as needed.

   console.log(byteArray);

This example logs the byte array to the console. By following these steps, you can convert a string to a byte array in JavaScript. Keep in mind that JavaScript uses Unicode characters, so each character may occupy more than one byte in memory. The resulting byte array contains the Unicode values of the characters. If you need to perform specific encoding or handle multi-byte characters, additional steps may be required.
