Step 3: After creating the ReactJS application, Install the validator module using the following command:

Project Structure: It will look like the following.

Step to Run Application: Run the application using the following command from the root directory of the project:
- The following will be the output if the user enters input without any space. You can see that the text remains as it is because there is no white space present in the input text.
- The following will be the output if the user enters input with white space from both the end. You can see that the final output text is trimmed from both the side by removing white space.
NOTE: In the above example, # is appended from both ends so that the user can see the result that white space is removed.
