   <p id="xyz"></p>

   <script>
      let myString = "JavaScript is Fun";
      let myArray = myString.split(" ");
      document.getElementById("xyz").innerHTML = myArray;
   </script>
   
</body>
</html>

JavaScript split() Syntax

The syntax of split() method in JavaScript is:

string.split(separator, limit)

Both separator (refers to a string or a regular expression) and limit (refers to a number) arguments are optional.

The separator argument is used to define the way to split the string. And the limit argument is used to limit the number of splits.

Important: Omitting the value of separator argument will return an array containing only one element as the whole string. For example:

HTML with JavaScript Code

<!DOCTYPE html>
<html>
<body>

   <p id="xyz"></p>

   <script>
      let myString = "JavaScript is Fun";
      let myArray = myString.split();
      document.getElementById("xyz").innerHTML = myArray;
   </script>
   
</body>
</html>

Output

Note: Omitting the limit argument split the whole string.
