get system name in javascript

You can use the os module in Node.js to get the system name in JavaScript. Here's an example code:

index.tsx
const os = require('os');
const systemName = os.hostname();
console.log(systemName); // prints the system name
111 chars
4 lines

Note that this method only works on the server-side when using Node.js. If you're running JavaScript in the browser, you won't be able to access the system name directly as JavaScript running in web browsers is sandboxed for security reasons.

Another way of getting the system name on the server-side is to read the environment variable COMPUTERNAME (for Windows systems) or HOSTNAME (for Unix-based systems) using process.env. Here's an example code:

index.tsx
const systemName = process.env.COMPUTERNAME || process.env.HOSTNAME;
console.log(systemName); // prints the system name
120 chars
3 lines

Keep in mind that the environment variables approach may not work on every system or setup, so using the os module is the most reliable way of getting the system name.
