Separate a string with a special character sequence into a pair of substrings in JavaScript?

Let’s say we have the following string with special character sequence −

var fullName=" John  Smith ";

To separate the above string into substring, use regex and then split(). The syntax is as follows −

var anyVariableName=(/\s*\s*/g);
var anyVariableName=yourVariableName.trim().split(yourVariableName);

Following is the complete JavaScript code −

Example

var fullName=" John  Smith ";
console.log("The Value="+fullName);
var regularExpression=(/\s*\s*/g);
var seprateName=fullName.trim().split(regularExpression);
console.log(seprateName);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo39.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo39.js
The Value= John  Smith
[ 'John', 'Smith' ]
