How to convert a JavaScript string to byte array using ASCII encoding?
In C#, it is done as:
var encoding = new System.Text.ASCIIEncoding();
byte[] keyByte = encoding.GetBytes(string);
I want to do the same in JavaScript for my nodejs server

You need to post the code you have already tried and explain where you are getting stuck. Please read [How to Ask a Good Question] and include an minimal reproducible example in your questionTibrogargan– Tibrogargan2016-07-29 06:30:15 +00:00Commented Jul 29, 2016 at 6:30

For Node.js this is fairly easy:
var keyByte = new Buffer(string, "ascii");
Buffer is a container of bytes, and can be treated as an array:
var bytes = new Buffer("Hello, world", "ascii");
console.log(bytes[3]); //writes 108
Most of the network and filesystem APIs take and return buffers

Update for NodeJS
const str = 'Hello world';
const buf = Buffer.from(str, 'ascii');
console.log(buf.toString('hex'));
console.log(buf.toString('base64'));
