Write a JavaScript program to get the middle character(s) from a given string.

Test Data:

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript program to Middle character(s) of a string</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function test(text) {
  var text_len = text.length;
  if (text_len % 2 != 0) 
  {
    let start = (text_len - 1) / 2;
    return text.slice(start, start + 1)
  } 
  else 
  {
    let start = text_len / 2 - 1;
    return text.slice(start, start + 2);
  }
 }
text = "abcd"
console.log("Original string: "+text);
console.log("Middle character(s) of the said string: "+test(text))
text = "abc"
console.log("Original string: "+text);
console.log("Middle character(s) of the said string: "+test(text))
text = "JavaScript"
