Rewrite the strjoin function without using rest parameters, using the arguments object instead.

Here is an example of the strjoin function, which concatenates all passed arguments into a string without using rest parameters, but with the help of the arguments object:

function strjoin(separator) {
  var result = '';
  for (var i = 1; i < arguments.length; i++) {
    result += arguments[i];
    if (i < arguments.length - 1) {
      result += separator;
    }
  }
  return result;
}

// Example usage:
console.log(strjoin(', ', 'apple', 'banana', 'cherry')); // "apple, banana, cherry"
