How to execute such a command?

Question

Node.js

let spawn = require('child_process').spawn;

let ls = spawn('wget url');

ls.stdout.on('data', data => {
  console.log(data);
});

ls.on('error', err => console.log(err));

Good day to all. Above you can see that I am trying to download a file using the console wget. So I know that in order to execute a command with arguments, you need to pass the command itself and an array of arguments to spawn. Is there a way to do exactly as shown above? So that only a line is transferred. Maybe there are some special characters?
Thank you all in advance
