You fetch remote branches with this command:

git fetch origin

Then the remote branches should show up locally:

git branch -a

You can apply a replace() method on your string with a regular expression:

string.replace(/^[ ]+|[ ]+$/g, "");

It will remove any leading/trailing spaces from your string.

Here's how you'd use it:

let string = "  Your string.  "
string = string.replace(/^[ ]+|[ ]+$/g, "");

// "Your string."

Yes, you can do this via the command line:

npm --version

Which will output the current version number of NPM on your machine:

8.5.1

NPM has a version command that lists out versions of NPM packages on your machine:

npm version

That will output something similar to this:

{
  test: '1.0.0',
  npm: '8.5.1',
  node: '17.6.0',
  v8: '9.6.180.15-node.13',
  uv: '1.43.0',
  zlib: '1.2.11',
  brotli: '1.0.9',
  ares: '1.18.1',
  modules: '102',
  nghttp2: '1.45.1',
  napi: '8',
  llhttp: '6.0.4',
  openssl: '3.0.1+quic',
  cldr: '40.0',
  icu: '70.1',
  tz: '2021a3',
  unicode: '14.0',
  ngtcp2: '0.1.0-DEV',
  nghttp3: '0.1.0-DEV'
}

Another function you could use:

function shuffle(array) {
  for (var i = array.length - 1; i > 0; i--) {
      var j = Math.floor(Math.random() * (i + 1));
      var temp = array[i];
      array[i] = array[j];
      array[j] = temp;
  }

  return array
}

It's an implementation of the Durstenfeld Shuffle.
