JavaScript: Reverse words in a given string

JavaScript String: Exercise-60 with Solution

Write a JavaScript function to reverse words in a given string.
Test Data:
("abc") -> "cba"
("JavaScript Exercises") -> "tpircSavaJ sesicrexE"
(1234) -> "It must be a string."

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript function to reverse words in a given string</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function test(text) {
   if (text.length === 0) 
    {
    return 'String should not be empty!'
     }
   if (typeof text !== 'string')
     {
       return 'It must be a string.'
     }
   var words = [];
  words = text.match(/\S+/g);
  var reverse_word = "";
  for (var i = 0; i < words.length; i++) {
     reverse_word += words[i].split('').reverse().join('') + " ";
  }
  return reverse_word
}
console.log(test("abc"))
console.log(test("JavaScript Exercises"))
console.log(test(1234))
