How to join arguments as string with spaces inbetween? [duplicate]

Question

How can I take all arguments (args) in an array and combine them into one variable with spaces in-between, but infinitely and less sketchy. I'm somewhat new to JavaScript, so I apologize if I'm missing something apperent.

var keyword = (args[0]);
if (args.length == 2) {
    keyword = (args[0] + " " + args[1])
} else if (args.length == 3) {
    keyword = (args[0] + " " + args[1] + " " + args[2])
};

args is an array. So you can join that array using array.join() method.

const keyword = args.join(' ');

A more safe and straight forward approach would be:

function formatKeywords(...items) {
  return items.join(' ');
}

function formatKeywords(...items) {
  return items.join(' ');
}

console.log('Handle empty args:', formatKeywords());
console.log('With args:', formatKeywords('aa', 'bb'));
